About Sierra

Sierra is a conversational AI company building autonomous AI agents that transform how businesses interact with their customers. Co-founded in 2023 by Bret Taylor (former Salesforce co-CEO and Twitter board chair) and Clay Bavor (former Google VP who led AR/VR and Labs initiatives), Sierra has quickly become one of the most closely watched AI startups in Silicon Valley. The company partners with major brands — including WeightWatchers, SiriusXM, Sonos, and OluKai — to deploy AI agents capable of handling complex customer interactions with empathy, nuance, and real-time problem-solving. Sierra's culture reflects its founders' pedigree: deeply technical, intensely customer-focused, and driven by the belief that AI agents should feel less like chatbots and more like trusted advisors. The company has raised substantial venture capital and operates from San Francisco, attracting top-tier talent from companies like Google, Meta, Salesforce, and OpenAI. With 7+ open openings spanning engineering, strategy, sales, legal, and operations, Sierra is in a rapid growth phase — a signal that new hires will have outsized impact and the opportunity to shape foundational processes. People want to work at Sierra because it sits at the intersection of cutting-edge AI research and real-world enterprise deployment. Unlike pure research labs, Sierra employees see their work in production with Fortune 500 companies. Unlike massive tech incumbents, the team is small enough that individual contributors directly influence product direction. The combination of world-class leadership, elite funding, and a genuinely novel product category makes Sierra one of the most compelling places to build a career in AI today.

Resume Tips for Sierra

critical

Lead with AI, ML, or Conversational Technology Experience

Sierra builds AI agents — your resume should immediately signal relevant domain experience. If you've worked on NLP, LLMs, chatbots, conversational interfaces, customer experience automation, or enterprise AI deployments, make these the first bullet points under each role. Even adjacent experience (working with APIs that integrate AI services, deploying models to production, or managing AI vendor relationships) should be surfaced prominently.

critical

Use Sierra's Own Language and Terminology

Sierra describes its products as 'AI agents' — not chatbots, not virtual assistants. Mirror this language throughout your resume. Reference concepts like 'agent development,' 'conversational AI,' 'autonomous agents,' and 'customer experience transformation.' Ashby's search and filter functionality means recruiters will literally search for these terms when reviewing candidate pools, so alignment with Sierra's vocabulary directly affects your visibility.

critical

Quantify Impact in Enterprise or Customer-Facing Contexts

Sierra deploys AI for major brands, so they value candidates who understand enterprise scale. Instead of writing 'improved customer satisfaction,' write 'redesigned support workflow for 2M+ annual customer interactions, reducing resolution time by 34%.' Numbers that demonstrate your ability to operate at scale — revenue influenced, users served, systems maintained, customers onboarded — resonate strongly with Sierra's hiring teams.

Format for Ashby's Parser: Clean Structure Over Fancy Design

Ashby's resume parser handles standard formats well but can struggle with multi-column layouts, text boxes, headers/footers containing critical info, and heavily designed templates. Use a single-column layout with clear section headers (Experience, Education, Skills). Save as PDF with selectable text — never submit an image-based PDF. Keep your name, email, and phone at the top of the document body, not in the header field.

recommended

Highlight Startup or High-Growth Company Experience

With 7+ open roles and a founding date of 2023, Sierra is scaling at breakneck speed. Experience at other high-growth startups — especially in the Series A through Series D stage — signals that you can thrive in Sierra's environment. Mention specific examples of building processes from scratch, wearing multiple hats, or shipping products under tight timelines. If you've only worked at large companies, emphasize instances where you operated with startup-like autonomy.

recommended

Showcase Cross-Functional Collaboration Skills

Sierra's 'Strategist, Agent Development' roles bridge technical and client-facing work, and even their engineering roles require deep collaboration with customer teams. Your resume should demonstrate that you've worked across disciplines — partnering with sales, product, engineering, or customer success teams to deliver outcomes. Use phrases like 'partnered with,' 'co-developed with,' and 'cross-functional initiative' to signal this competency.

recommended

Include Relevant Technical Skills in a Dedicated Section

For engineering roles, list specific technologies in a skills section that Ashby can parse: Python, TypeScript, React, distributed systems, Kubernetes, PostgreSQL, LLM fine-tuning, prompt engineering, RAG architectures, and cloud platforms (AWS, GCP). For non-technical roles, include tools relevant to your function (Salesforce, HubSpot, Notion, Figma, SQL) to ensure you appear in filtered searches.

Keep It to One Page (Two Maximum for Senior Roles)

Sierra's recruiters are reviewing a high volume of applications across 144+ roles. A concise, impactful resume respects their time and demonstrates your ability to prioritize — a core skill at any startup. Senior engineers or directors with 15+ years of experience can justify two pages, but every line should earn its place. Remove outdated skills, irrelevant early-career roles, and generic objective statements.

ATS System: Ashby

Ashby is a modern, all-in-one recruiting platform favored by high-growth startups for its powerful analytics, structured hiring workflows, and candidate-friendly application experience. Sierra uses Ashby to manage its entire hiring pipeline — from application intake and resume parsing to interview scheduling and offer management. Ashby's structured data approach means your application information is parsed, categorized, and searchable by Sierra's recruiting team.

  • Use a single-column PDF resume with selectable text — Ashby parses these most reliably and avoids the extraction errors common with complex layouts
  • Place your name, email, phone number, and LinkedIn URL in the main document body rather than in headers or footers, which Ashby's parser may skip
  • Mirror exact job title keywords from Sierra's listing in your resume — Ashby enables recruiters to search and filter candidate pools by specific terms
  • Complete every field in the application form thoroughly, as Ashby stores structured data that recruiters use for filtering; blank optional fields are missed opportunities
  • Avoid tables, text boxes, icons, and graphics in your resume — Ashby's parser converts your document to structured text, and visual elements often break during conversion
  • If applying to multiple Sierra roles, tailor each submission — Ashby tracks all your applications under a single candidate profile, and recruiters can see every version you've submitted
  • Use standard section headers like 'Experience,' 'Education,' and 'Skills' so Ashby correctly categorizes your resume content into the right fields

Interview Culture

Sierra's interview process reflects the intensity and intellectual curiosity of a company founded by two of tech's most accomplished leaders.

Expect a process that is rigorous but respectful — Sierra is competing for top talent and knows that the interview experience matters. The typical process spans 3-5 rounds over two to four weeks, though Sierra's recruiting team often moves quickly for strong candidates given the pace of their growth. After the recruiter screen, you'll engage directly with the hiring manager for a role-specific deep dive. Engineering candidates should prepare for live coding or system design sessions that emphasize practical problem-solving — think building scalable data pipelines for AI agents, designing reliability into LLM-powered systems, or architecting platform services that handle millions of customer conversations. Sierra's engineering bar is high, drawing comparisons to top-tier companies like Google and Stripe. For Strategist and Agent Development roles — Sierra's signature hybrid position — interviews commonly include case studies that simulate real client engagements. You might be asked to diagnose why an AI agent is underperforming for a retail brand, design an agent deployment strategy for a new vertical, or present a plan to expand an existing client relationship. These exercises test both analytical rigor and client communication skills. Sales and business roles typically include a presentation or mock pitch component, with interviewers evaluating your ability to articulate Sierra's value proposition to enterprise decision-makers. Culture fit is assessed throughout, not in a single dedicated session. Sierra values intellectual humility, urgency without recklessness, and genuine curiosity about AI's potential to transform customer experiences. Interviewers often probe for how you handle ambiguity, learn from failure, and collaborate across disciplines. Demonstrating that you've used or studied Sierra's product, read interviews with their founders, or have a thoughtful perspective on the future of AI agents will distinguish you from candidates who treat the interview as transactional.

What Sierra Looks For

  • Deep intellectual curiosity about AI agents and conversational technology — Sierra wants people who are genuinely fascinated by the problem space, not just seeking a prestigious brand name
  • Comfort with ambiguity and rapid iteration — as a 2023-founded company scaling to 144+ roles, Sierra operates at a pace where perfect information is rare and speed of learning matters
  • Enterprise customer empathy — whether you're an engineer, strategist, or salesperson, Sierra expects you to understand and care about the end-customer experience their AI agents deliver
  • Technical depth paired with communication clarity — Sierra's Strategist roles explicitly bridge engineering and client work, and even pure engineering roles require explaining complex systems to non-technical stakeholders
  • Ownership mentality and bias toward action — at Sierra's stage, waiting for permission or detailed specifications is incompatible with the company's velocity
  • Track record of excellence at high-caliber organizations — Sierra's team includes alumni from Google, Salesforce, Meta, and top AI labs, and they hire people who have demonstrated top-percentile performance in demanding environments
  • Collaborative instincts across functions — Sierra's product requires engineering, strategy, sales, and customer success to work in tight coordination, so lone-wolf tendencies are a red flag

Frequently Asked Questions

How long does Sierra's hiring process typically take from application to offer?
Based on patterns common at high-growth AI startups of Sierra's size and stage, the process typically takes two to four weeks from first recruiter contact to offer. However, the total timeline from application submission to first contact can vary depending on role demand and candidate volume — some applicants report hearing back within a few days, while others wait one to two weeks. Sierra is growing rapidly with 7+ open roles, which suggests their recruiting team is actively working to fill positions efficiently. Preparing your materials in advance and responding promptly to scheduling requests can help keep your process moving at the faster end of the range.
Does Sierra require a cover letter with applications?
Sierra's Ashby-powered application forms vary by role — some include an optional cover letter field, while others do not. When the option is available, submitting a tailored cover letter is strongly recommended, particularly for Strategist, Sales, and Legal roles where written communication is core to the job. Your cover letter should address why you're specifically drawn to Sierra's mission of building AI agents (not AI broadly), reference a specific Sierra customer deployment or founder interview that resonated with you, and concisely explain what you'd bring to the role. Keep it under 300 words — Sierra's team values precision over volume.
What experience level does Sierra typically hire for?
Sierra hires across a range of experience levels, though the distribution skews toward mid-career and senior professionals given the company's technically demanding product and enterprise customer base. Job titles like 'Senior Corporate Counsel,' 'Sales Director,' and 'Software Engineer, Platform' suggest they're seeking candidates with meaningful domain expertise. That said, Sierra also posts contract roles (Office Manager, Office Coordinator) and business function positions (Business Recruiter) that may be accessible to candidates earlier in their careers. For engineering specifically, Sierra's bar is high — expect requirements comparable to top-tier tech companies, with a premium on AI/ML experience or systems engineering at scale.
How should I prepare for a Sierra engineering interview?
Sierra's engineering interviews typically assess both fundamental computer science skills and domain-specific knowledge relevant to building AI agent platforms. Prepare for system design questions that involve real-time conversational systems, scalable data pipelines, and LLM integration challenges. Practice coding in your strongest language (Python and TypeScript are commonly used at Sierra), and be ready to discuss trade-offs in areas like latency, reliability, and cost optimization for AI workloads. Review Sierra's public engineering blog posts or technical talks if available. Most importantly, be prepared to explain how your past work connects to Sierra's mission — interviewers want to see that you understand the unique engineering challenges of deploying AI agents for enterprise customers at scale.
What is the 'Strategist, Agent Development' role at Sierra?
The Strategist, Agent Development role is one of Sierra's most distinctive positions — a hybrid function that combines technical consulting, AI agent design, and client partnership. Strategists work directly with Sierra's enterprise customers to design, build, and optimize AI agents tailored to each company's specific needs and brand voice. This requires a blend of technical fluency (understanding how LLMs work, prompt engineering, agent behavior design), business acumen (mapping AI capabilities to client KPIs), and client management skills. The fact that Sierra is hiring for this role in both English and French-speaking markets indicates international expansion. Candidates with backgrounds in management consulting, solutions engineering, technical program management, or customer-facing AI/ML roles are typically strong fits.
Can I apply to multiple roles at Sierra simultaneously?
Yes, you can apply to multiple Sierra positions, but do so strategically. Ashby consolidates all your applications under a single candidate profile, meaning Sierra's recruiters can see every role you've applied to and every version of your resume you've submitted. Applying to two or three closely related roles (for example, two engineering positions on different teams) is reasonable and shows focused interest. However, applying to ten disparate roles — say, Software Engineer, Office Coordinator, and Sales Director — signals a lack of clarity about your career goals and can work against you. Tailor your resume for each submission, emphasizing the specific skills and experience most relevant to each position.
Does Sierra offer remote work options?
Sierra is headquartered in San Francisco, and based on their job listings and the presence of contract Office Manager and Office Coordinator roles, the company maintains a meaningful in-office presence. Many high-growth AI startups at Sierra's stage prioritize in-person collaboration, particularly for engineering and strategy teams where rapid iteration and whiteboarding are central to the work. That said, specific roles — especially those involving international markets like the French-speaking Strategist position — may offer location flexibility. Review each job listing carefully for location requirements, and ask your recruiter directly during the initial screen about the team's specific work arrangement rather than assuming a blanket remote policy.
How can I make my application stand out among Sierra's high volume of applicants?
With 7+ open openings and significant industry buzz, Sierra receives substantial application volume. Three strategies can differentiate your candidacy. First, demonstrate genuine product knowledge — mention specific Sierra customer deployments, quote insights from Bret Taylor's or Clay Bavor's public talks, or describe how you've interacted with an AI agent built on Sierra's platform. Second, seek a referral from a current Sierra employee, as Ashby's referral tracking ensures these applications receive prioritized review. Third, make your application materials frictionless to evaluate — a clean, Ashby-optimized resume with clear metrics, relevant terminology, and a logical narrative reduces the cognitive load on recruiters reviewing hundreds of candidates. The goal is to make it immediately obvious why you belong at Sierra, not to force the recruiter to piece together your relevance from scattered clues.
What is Sierra's interview format for non-technical roles like Sales Director or Corporate Counsel?
Non-technical roles at Sierra typically follow a structured multi-round process tailored to the function. Sales Director candidates can expect a recruiter screen, a hiring manager deep-dive on pipeline management and enterprise sales methodology, a mock pitch or deal review exercise where you present Sierra's value proposition to simulated enterprise buyers, and a final panel with cross-functional leaders. Corporate Counsel candidates will likely face scenario-based discussions on topics relevant to AI companies — data privacy, IP protection, commercial contract negotiation, and regulatory considerations. Both tracks will include culture fit assessment woven throughout, with interviewers evaluating your alignment with Sierra's pace, intellectual curiosity, and customer-centric values. Prepare concrete examples of complex deals closed, contracts negotiated, or legal strategies developed, with a focus on technology or AI industry contexts where possible.
