How to Apply to Chan Zuckerberg Initiative

Key Takeaways

CZI is an LLC, not a traditional nonprofit — donations are not tax-deductible, but the structure lets CZI fund science, build software, and invest strategically from one entity. Understand this before you apply.
Every open role flows through Greenhouse at job-boards.greenhouse.io/chanzuckerberginitiative — submit a clean, text-based PDF and fill in every field.
Write a real, role-specific answer to the 'Why CZI?' question; it is the single most-read part of your application.
CZI's 2024-2025 hiring posture leans heavily toward AI-for-biology (Virtual Cells, the Biohub Network) and AI-for-education (Learning Commons); tune your resume accordingly.
Expect 4-5 interview rounds with an explicit values panel; prepare STAR-format stories about ambiguity, cross-disciplinary collaboration, and a project that did not work.
The 2024 wind-down of much of CZI's advocacy work is real; acknowledge it honestly if it comes up rather than pretending nothing changed.
Redwood City HQ is hybrid (approximately 3 days in office) for most roles; Biohub roles sit in SF, Chicago, or New York; assume you need a relocation or commute story.
Compensation is competitive with large Bay Area tech; salary ranges are published on every Greenhouse posting per California pay transparency law.
Values interviews are decisive — technical excellence without mission fit will not get you to offer, and mission fit without technical excellence will not either.
Referrals materially help; if you know a current CZI employee, name them in the Greenhouse referral field.

About Chan Zuckerberg Initiative

The Chan Zuckerberg Initiative (CZI) was founded in December 2015 by Priscilla Chan and Mark Zuckerberg with a founding letter pledging 99% of their Facebook (now Meta) shares, over time, toward 'advancing human potential and promoting equality.' It is headquartered at 1 Main Street in Redwood City, California, and employs roughly 800 people across its Redwood City headquarters and its Biohub research hubs in San Francisco, Chicago, and New York. CZI is organized as a limited liability company (LLC) rather than a traditional 501(c)(3) private foundation — a structure that means donations to CZI are not tax-deductible in the way gifts to a classical nonprofit are, but that also lets CZI legally fund scientific research through grants, build software as an operating company, participate in policy advocacy, and make mission-aligned for-profit investments, all from one entity. That hybrid structure is the single most important thing a candidate needs to internalize before writing their cover letter. CZI is not a charity in the traditional sense. It is a mission-driven operating company whose shareholders happen to be Priscilla Chan and Mark Zuckerberg, and whose output is concentrated in two flagship program families. The Science program, anchored by the CZ Biohub Network (UCSF/Stanford/Berkeley, the Chicago Biohub, and the New York Biohub) and by an in-house Science Technology group, pursues a long-horizon goal the founders articulated as 'curing, preventing, or managing all disease by the end of this century.' In 2024 and 2025, CZI publicly sharpened that goal into what it now calls 'AI-for-biology,' centered on building Virtual Cells — foundation models that predict cellular behavior — and on open scientific tooling, single-cell atlases, and imaging infrastructure that any researcher in the world can use. The Learning Commons program (formerly branded as the education portfolio that included tools like Summit Learning) builds AI-powered infrastructure that supports teachers, students, and the platforms they rely on day-to-day. A third, quieter line of work supports Bay Area community organizations and Justice and Opportunity programs, largely through a co-founded vehicle called the Chan Zuckerberg Community Fund and partner nonprofits. A candidate preparing to apply in 2026 should also be honest about context. In late 2024, CZI announced a significant restructuring that wound down or spun out large portions of its social advocacy and Justice and Opportunity work, pivoting head-count and budget toward AI-for-science. That pivot drew genuine criticism from civil-society partners and some former staff. Additionally, anything attached to Mark Zuckerberg's name inherits public scrutiny of Meta — content moderation, privacy, AI safety, political exposure — and interviewers will expect candidates to have a thoughtful, adult view of that reality rather than either fandom or reflexive dismissal. The compensation is competitive with large Bay Area tech employers (base salary ranges are published on every job posting in accordance with California pay transparency law), benefits are strong, and the tooling is well-funded. The trade is that you are joining a values-driven organization where mission fit is genuinely weighted in hiring, where priorities can shift when the founders shift, and where the work — curing disease, helping teachers, supporting communities — is meant to be both technically rigorous and personally meaningful. If that trade appeals to you, CZI is one of the most interesting places in the Bay Area to work.

Application Process

1
Start at chanzuckerberg
Start at chanzuckerberg.com/careers, which redirects into the Greenhouse-hosted job board at job-boards.greenhouse.io/chanzuckerberginitiative. Every public CZI opening — whether it is a Biohub research scientist role, a Science Technology ML engineer, a Learning Commons software engineer, or an Operations/Legal/Communications role — flows through the same Greenhouse instance, so there is no separate 'science' or 'engineering' portal to hunt down.
2
Filter by team and location
Filter by team and location. CZI hires heavily against its Redwood City headquarters (hybrid, 3 days in office is the current norm), with a meaningful Chicago presence for Biohub Chicago infrastructure and expanding New York roles for Biohub NY. A small number of roles are fully remote, but assume hybrid-by-default and plan your relocation story before you apply.
3
Create a Greenhouse candidate profile and upload your resume as a PDF generated
Create a Greenhouse candidate profile and upload your resume as a PDF generated from a text-based document (not a scanned image). Greenhouse's parser will auto-populate the application form; proofread every field because parsing errors become recruiter first impressions.
4
Write a cover letter or 'Why CZI' response for every application
Write a cover letter or 'Why CZI' response for every application. CZI's application flow almost always includes a free-text 'Why are you interested in this role at CZI?' or 'What draws you to our mission?' question. Skipping it or writing two generic sentences is the single most common self-inflicted rejection. Answer it specifically — name the program (Biohub, Learning Commons, Community), name the initiative (Virtual Cells, CELLxGENE, a specific Learning Commons product), and connect it to something concrete you have done.
5
Expect voluntary self-identification questions (race, gender, veteran status, di
Expect voluntary self-identification questions (race, gender, veteran status, disability) at the end of the application. These are used only for aggregate EEO reporting and are not visible to the hiring team; declining to answer does not affect your candidacy.
6
After submission, most candidates hear back within 2-3 weeks for active roles an
After submission, most candidates hear back within 2-3 weeks for active roles and within 4-6 weeks for roles with large applicant pools. CZI recruiters are generally responsive; if you have not heard anything after 3 weeks it is appropriate to follow up once, politely, through Greenhouse's messaging or through a recruiter you have met.
7
Recruiter screen (30 minutes, phone or Google Meet): a CZI recruiter will confir
Recruiter screen (30 minutes, phone or Google Meet): a CZI recruiter will confirm role fit, salary expectations against the posted range, work authorization, location and hybrid flexibility, and — critically — why you specifically want to work at CZI rather than at a pure-play tech company or a traditional nonprofit. Prepare a clean 90-second answer to that question.
8
Hiring manager interview (45-60 minutes): focused on your relevant experience an
Hiring manager interview (45-60 minutes): focused on your relevant experience and your understanding of the team's actual work. For technical roles, expect to be asked to walk through a past project end-to-end, including the trade-offs you considered and what you would do differently.
9
Technical or craft loop (varies by role): engineers receive a take-home or live
Technical or craft loop (varies by role): engineers receive a take-home or live coding exercise plus a systems/architecture discussion; research scientists present their past work and discuss a proposed line of inquiry; product managers run through a product-critique or prioritization exercise; operations and legal candidates work through scenario-based case questions grounded in CZI's actual operating reality.
10
Values and cross-functional interviews (2-3 conversations): CZI weights 'values
Values and cross-functional interviews (2-3 conversations): CZI weights 'values alignment' heavily and will explicitly interview for it. You will talk with peers and partners from outside your immediate team — sometimes a scientist if you are applying to an engineering role, sometimes an engineer if you are applying to a program role — to assess collaboration style, intellectual humility, and comfort working across disciplines.
11
Final onsite or virtual loop (3-5 hours): a consolidated panel that usually incl
Final onsite or virtual loop (3-5 hours): a consolidated panel that usually includes a skip-level leader and one 'bar raiser' style interviewer from another org. Expect at least one conversation explicitly about how you handle ambiguity, shifting priorities, and mission trade-offs.
12
Offer and reference stage: CZI typically asks for 2-3 professional references an
Offer and reference stage: CZI typically asks for 2-3 professional references and will conduct a standard background check. Offers include base salary within the posted range, an annual performance bonus, equity-equivalent long-term incentive (CZI is not publicly traded; instead of stock it offers a cash-based long-term incentive tied to tenure), and a competitive benefits package.

Resume Tips for Chan Zuckerberg Initiative

recommended

Lead with mission-relevant impact, not headcount

Lead with mission-relevant impact, not headcount. CZI hires people who can point to outcomes (patients helped, students reached, scientific tools adopted, dollars deployed responsibly) rather than people whose resumes read as a tour of logos. Rewrite your top three bullets to start with a measurable outcome, not a team size.

recommended

Use the exact program vocabulary CZI uses

Use the exact program vocabulary CZI uses. Greenhouse's parser plus human screeners react well to terms pulled directly from the job description and from CZI's public materials: 'Biohub Network,' 'Learning Commons,' 'AI-for-biology,' 'Virtual Cells,' 'single-cell,' 'open science,' 'Central Tech,' 'Science Technology.' Do not stuff keywords — integrate them into real accomplishments.

recommended

If you are applying to a Science or Science Technology role, surface publication

If you are applying to a Science or Science Technology role, surface publications, preprints, open-source contributions, and dataset or tool releases near the top. CZI genuinely reads these. A link to a cited bioRxiv preprint or a maintained GitHub repo is worth more than an extra job bullet.

recommended

If you are applying to Learning Commons or any education-adjacent role, concrete

If you are applying to Learning Commons or any education-adjacent role, concretely demonstrate that you have shipped product for teachers, students, or district administrators. Abstract ed-tech experience is less valuable than a specific example of reducing a teacher's workload or improving a measurable student outcome.

recommended

For engineering roles, call out AI and machine learning work specifically when i

For engineering roles, call out AI and machine learning work specifically when it is real. CZI's 2024-2025 hiring is weighted heavily toward engineers who can work at the intersection of ML infrastructure and biology or education — foundation models, RAG systems, data pipelines for multi-modal scientific data, evaluation harnesses, and responsible AI practices.

recommended

Quantify without inflating

Quantify without inflating. A good CZI resume bullet looks like: 'Shipped v1 of the single-cell variant-calling pipeline that processes 12M cells/day across 3 Biohub sites, cutting analyst turnaround from 4 days to 6 hours.' A weak one reads: 'Led impactful initiatives to improve scientific workflows.'

recommended

Keep it to 1-2 pages

Keep it to 1-2 pages. Even for senior scientists, the resume is a pointer to your portfolio, not the portfolio itself. Link out (ORCID, Google Scholar, GitHub, personal site) rather than padding the document.

recommended

Spell out degrees, institutions, and graduation dates for technical and scientif

Spell out degrees, institutions, and graduation dates for technical and scientific roles — CZI hiring managers in the Biohub Network expect to see them. For business, operations, and legal roles a standard professional resume format is fine.

recommended

Show evidence of cross-disciplinary collaboration

Show evidence of cross-disciplinary collaboration. CZI explicitly prizes people who can translate between scientists, engineers, and program staff. A bullet that reads 'Served as the technical liaison between the wet-lab imaging team and the cloud infrastructure team' lands harder at CZI than at most other employers.

recommended

Acknowledge your mission arc

Acknowledge your mission arc. Somewhere in your summary or cover letter, make your choice of CZI intentional. 'After six years shipping consumer ML at Meta, I want to apply the same craft to disease research' reads well. 'I like the benefits' does not.

recommended

Export from a modern word processor (Google Docs, Word, Pages) straight to PDF

Export from a modern word processor (Google Docs, Word, Pages) straight to PDF. Avoid image-based PDFs, scanned documents, and templates with multi-column layouts or embedded text boxes — all three break Greenhouse's resume parser and create a messy first impression.

recommended

Proofread mercilessly for the founders' names and program names

Proofread mercilessly for the founders' names and program names. Spelling it 'Chan-Zuckerberg Initiative' with a hyphen, or calling the program 'CZ Initiative,' signals inattention. The correct forms are 'Chan Zuckerberg Initiative' and 'CZI.'

ATS System: Greenhouse

CZI uses Greenhouse as its applicant tracking system. All public CZI roles are hosted at job-boards.greenhouse.io/chanzuckerberginitiative (the careers page at chanzuckerberg.com/careers links through to this board). Greenhouse is the standard ATS across mission-driven tech companies and the Bay Area; it parses resume text cleanly as long as you give it a text-based PDF, and it stores your full application — resume, uploaded documents, answers to custom questions, and your self-identification responses — in a single candidate record that every CZI interviewer for a given role can see. Greenhouse does not rank applicants algorithmically at CZI; recruiters and hiring managers review applications manually. The ATS does, however, make it easy for CZI to track which sourcing channels produce which hires, so your cover letter and 'Why CZI' answer are disproportionately visible to the team.

Submit a text-based PDF exported from a word processor. Scanned or image-only PDFs will parse as garbage and look careless to the reviewer.
Fill in every optional field in the Greenhouse application — LinkedIn URL, portfolio URL, pronouns, work authorization — rather than letting the parser approximate them.
Write a substantive, role-specific answer to CZI's 'Why are you interested in this role?' free-text question. This is the field most recruiters read first.
Use direct, scannable resume formatting: a single column, standard section headings (Experience, Education, Skills, Publications/Projects), and no headers, footers, text boxes, or graphics that parsers often drop.
Keep filenames professional and searchable: 'FirstName_LastName_Resume_CZI.pdf' rather than 'resume_final_v4(1).pdf'. Recruiters download many files a day.
If you are a returning applicant or have been referred, mention it explicitly in the application form's referral field. CZI runs an active referral program and referred candidates do get expedited first-screen review.
Only apply to 2-3 open roles at a time. Submitting to every open Greenhouse requisition at CZI is visible across the recruiting team and signals a lack of focus.

Interview Culture

CZI's interview culture is best described as 'warm but rigorous, with real weight on values.' The warmth is not performative: interviewers will tell you about the mission, walk you through how their team fits into Biohub or Learning Commons, and treat the conversation as a two-way evaluation rather than a puzzle. The rigor is real: for engineering and science roles you should expect a technical bar comparable to any serious Bay Area tech company, and for legal, program, finance, and operations roles you should expect scenario-based questions grounded in CZI's actual operating complexity (an LLC funding a nonprofit Biohub, multi-site research, AI safety and data governance for biomedical data, California pay transparency, procurement across research institutes). The distinctive feature of CZI interviewing is the explicit values panel. Every candidate, across every role, talks with at least one interviewer whose job is to probe 'values alignment.' In practice this means two things. First, how do you handle ambiguity, shifting priorities, and the fact that CZI's roadmap depends on funder direction — can you stay productive and motivated when the mission tightens, as it did in the 2024 pivot to AI-for-science? Second, can you work across disciplines without ego? CZI deliberately staffs teams that mix scientists, engineers, program staff, and policy experts, and the cultural ask is that you can speak a little of everyone's language and respect that the biologist on the call knows things you do not. Expect behavioral questions framed around CZI's operating values, which center on curiosity, humility, rigor, collaboration, and long-term mission commitment. Use the STAR format (Situation, Task, Action, Result), pick examples that show genuine interdisciplinary collaboration, and be willing to talk about a project that did not work. Finally, be prepared — especially if the role is AI-adjacent — for thoughtful conversations about responsible AI, data privacy in biomedical contexts, and the relationship between CZI and Meta. Interviewers will not grill you with gotchas, but they will notice if you have not thought about it. The decision timeline from first screen to offer is typically 3-5 weeks, occasionally longer for senior scientific roles that require convening multiple Biohub stakeholders.

What Chan Zuckerberg Initiative Looks For

Genuine mission fit, not performative mission fit. CZI interviewers can tell the difference between a candidate who has read the 2015 founding letter, the 2024-2025 AI-for-science announcements, and at least one Biohub or Learning Commons piece of public work, versus a candidate repeating talking points.
Demonstrated ability to work across disciplines. The most successful CZI employees can sit at a table with a research scientist, a software engineer, a program manager, and a policy lead and contribute usefully in every direction.
Technical excellence calibrated to CZI's current bar. For Science Technology and Central Tech roles that bar is at or above FAANG engineering loops, with additional weight on responsible AI, data privacy, and research software engineering fundamentals.
Scientific credibility for research and research-adjacent roles. Publications, preprints, open-source scientific tooling, dataset releases, and a track record of working with or inside academic/research communities all count.
Adult comfort with the LLC context and with the Zuckerberg association. Candidates who cannot engage with the criticism of CZI's structure or with Meta-adjacent scrutiny — either by defending it thoughtfully or by articulating honest tensions — tend not to advance.
Resilience under priority shifts. CZI has reorganized meaningfully in each of the last three years; the team looks for people who can ship under changing direction rather than people who need a static mandate.
Craft and communication. Because CZI's work is public-facing (open-source tools, open-access papers, publicly-funded partners), interviewers weight written and spoken communication heavily, even for deep-technical roles.
Bias toward open science, open tools, and open data. If your past work has contributed to open-source projects, open datasets, public benchmarks, or free tools for teachers, surface it.
Evidence of long-term thinking. 'Curing or preventing all disease by the end of the century' is a literal planning horizon inside CZI; candidates who can articulate how a 3-year project lives inside a 30-year arc fare well.
Humility and a growth mindset. CZI, in interview debriefs, heavily weights 'does this person make their colleagues better' over 'is this person individually impressive.'

Frequently Asked Questions

Is the Chan Zuckerberg Initiative a nonprofit?

No, not in the traditional sense. CZI is organized as a limited liability company (LLC) rather than as a 501(c)(3) private foundation. Donations to CZI are not tax-deductible the way gifts to a classical charity are, but the LLC structure lets CZI do several things a foundation legally cannot: fund scientific research via grants, operate as a software company, lobby and engage in policy advocacy, and make mission-aligned for-profit investments, all under one entity. Some CZI-adjacent programs — notably the Biohub Network institutes — are themselves nonprofits funded largely by CZI. This hybrid structure is by design and is the first thing any serious candidate should understand.

What ATS does CZI use and where do I actually apply?

CZI uses Greenhouse. Every public CZI role is hosted at job-boards.greenhouse.io/chanzuckerberginitiative. The main careers page at chanzuckerberg.com/careers links out to the same Greenhouse board. There is no separate portal for Biohub, Learning Commons, Science Technology, or Operations roles — they all live on the same board.

Does CZI hire remote, or do I need to move to Redwood City?

Most non-Biohub roles are based at CZI's Redwood City headquarters and are hybrid, with an expectation of roughly 3 days in office per week. Biohub roles are site-specific (San Francisco, Chicago, or New York). A small number of roles are fully remote, but assume hybrid-by-default, and work out your relocation or commute story before you interview.

What kinds of roles is CZI hiring for right now?

The current mix (2025-2026) is weighted toward AI-for-biology and scientific infrastructure (Biohub Network scientists, ML/infra engineers on Science Technology, data engineering, responsible AI, security and networking for research sites), toward Learning Commons engineering and program staff, and toward a steady base of Operations, Finance, Legal, Communications, and Security roles that support the whole initiative. On any given week the public Greenhouse board lists on the order of 10-7+ open roles.

What is the interview process like?

Most candidates experience a 4-5 round process: a recruiter screen, a hiring-manager interview, one or more technical or craft interviews (coding exercise, systems design, research talk, or scenario-based case depending on the role), a dedicated values-alignment interview, and a final panel that typically includes a skip-level leader. Total wall-clock time from first screen to offer is 3-5 weeks for most roles and can be longer for senior scientific positions.

How much does CZI weight 'values fit' versus technical skill?

Both are required and neither is sufficient on its own. Strong technical candidates without a credible, specific mission fit routinely fail the values interview. Strong mission-driven candidates without the skill level to do the actual job do not receive offers either. Prepare to demonstrate both.

How should I think about the 2024 restructuring and mission pivot?

Be honest. In late 2024, CZI announced a significant wind-down and spin-out of portions of its social advocacy and Justice and Opportunity work, pivoting resources toward AI-for-science. Some former staff and civil-society partners have been critical. You do not need to take a side, but you do need to have thought about it. Interviewers will respect a candid answer — 'I understand CZI is concentrating on AI-for-biology and open science, and that's the work I want to do' — far more than either denial or a hostile posture.

Is CZI the same thing as Meta? Does working there involve working on Facebook or Instagram?

No. CZI is legally, financially, and operationally separate from Meta Platforms. Mark Zuckerberg is a co-founder of both, and CZI is funded by his and Priscilla Chan's pledged personal wealth (denominated largely in Meta shares), but CZI has its own headquarters, its own leadership team (Priscilla Chan is co-founder and co-CEO and plays a deeply active operating role, with a medical background that increasingly sets the scientific direction), its own hiring pipeline, and its own product portfolio. You will not be building Facebook features at CZI.

Does CZI sponsor work visas?

CZI sponsors work visas for many roles, particularly research-scientist, senior engineering, and specialized technical positions. Sponsorship is not guaranteed for every role — junior and highly generalist positions are less likely to be sponsored. The Greenhouse application and the recruiter screen both ask about work authorization early; answer honestly, and if you require sponsorship say so up front rather than at offer stage.

What does CZI pay, and is there equity?

Base salary ranges are published on every CZI Greenhouse posting as required by California pay transparency law and tend to be competitive with large Bay Area tech employers for comparable roles. CZI also pays an annual performance bonus and a long-term incentive. Because CZI is a privately held LLC and not a publicly traded company, the long-term incentive is a cash-based program tied to tenure rather than publicly-tradable stock. Benefits (health, retirement, parental leave) are strong and explicitly among the reasons employees cite for staying.

I have no biology or education background — can I still get hired?

Yes, for many roles. CZI hires software engineers, security engineers, program managers, designers, communications staff, lawyers, finance professionals, and operations leaders who did not come from biology or education backgrounds. What is non-negotiable is curiosity and willingness to learn the domain. If you are applying to a role on a Biohub-adjacent team, read a few recent Biohub papers or blog posts before your recruiter screen so that you can speak to the work in plain terms.

How should I actually get noticed at CZI?

Four things, in priority order: (1) apply to a small number of roles you are genuinely qualified for rather than many roles you might be; (2) write a substantive, specific answer to the 'Why CZI?' free-text question that names a real program and connects it to real past work; (3) use your network — CZI runs an active referral program, and a referral meaningfully expedites first-screen review; (4) keep your resume to one or two clean pages, exported as a text-based PDF, and use the vocabulary of CZI's current programs (Biohub Network, Learning Commons, AI-for-biology, Virtual Cells, open science).
