Key Takeaways

  • 75% of U.S. employers use automated applicant tracking systems to screen resumes before a human reviews them (Harvard Business School & Accenture, 2021)
  • The most common ATS failures are missing keywords, incompatible formatting, and incorrect file types
  • ResumeGeni scores your resume across 8 parsing layers — modeled on the same steps enterprise ATS platforms like Workday, Greenhouse, and Taleo use to evaluate candidates

How ATS Resume Scoring Works

Applicant tracking systems parse your resume into structured data — extracting your name, contact info, work history, skills, and education — then score how well that data matches the job requirements. Many ATS rejections happen because the parser couldn't extract critical fields, not because the candidate wasn't qualified.

LayerWhat It ChecksWhy It Matters
Document extractionFile format, encoding, readabilityCorrupted or image-only PDFs fail immediately
Layout analysisTables, columns, headers, footersMulti-column layouts break field extraction
Section detectionExperience, education, skills headingsNon-standard headings cause sections to be missed
Field mappingName, email, phone, dates, titlesMissing contact info is a common cause of immediate rejection
Keyword matchingJob-specific terms, skills, certificationsKeyword overlap affects recruiter search visibility and ATS scoring
Chronology checkDate ordering, gap detectionReverse-chronological order is expected by most ATS
QuantificationMetrics, numbers, measurable outcomesQuantified achievements help human reviewers and some scoring models
Confidence scoringOverall parse quality and completenessLow-confidence parses get deprioritized in results

Frequently Asked Questions

Is ResumeGeni free?
Yes. ResumeGeni is currently in beta — ATS analysis, scoring, and initial improvement suggestions are free with no signup required. Full guidance and saved reports may require a free account.
What file formats are supported?
PDF, DOCX, DOC, TXT, RTF, ODT, and Apple Pages. PDF and DOCX are recommended for best ATS compatibility.
How is the ATS score calculated?
Your resume is processed through an 8-layer parsing pipeline that extracts structured data the same way enterprise ATS platforms do. The score reflects how completely and accurately your resume can be parsed, plus how well your content matches common ATS ranking criteria.
Can ATS read PDF resumes?
Yes, but not all PDFs are equal. Text-based PDFs parse well. Image-only PDFs (scanned documents) and PDFs with complex tables or multi-column layouts often fail ATS parsing. Our analyzer will flag these issues.
How do I improve my ATS score?
Focus on three areas: use a clean single-column format, include keywords from the job description naturally in your experience bullets, and ensure all sections (contact, experience, education, skills) use standard headings.

Engineering Manager, SDKs

Stainlessapi · New York Office

About Stainless

Stainless is a fast-growing tech startup building the future of APIs. Our customers include industry leaders like OpenAI, Anthropic, and Cloudflare.

We have raised over $35 million from a16z, Sequoia, and founders/C-levels from Stripe, Datadog, Segment, Linear, and more.

We are headquartered in NYC, just west of SoHo, and are a team of ~60 strong expecting to double in the next ~9 to 12 months.

About the Role

You’ll lead product development for our SDK generator, a “compiler” from OpenAPI specs to idiomatic wrapper libraries in various languages for customers including OpenAI, Anthropic, and Cloudflare.

You’ll be one of 2 engineering leaders overseeing Stainless Engineering and will manage 6-12 engineers. This role reports to the CEO and is onsite at our office in Manhattan.

What you'll do

  • Support engineers in shipping new SDK generator features quickly and achieving high level of technical quality.

  • Hold our bar of “what library would an expert in the language create if they had infinite time”.

  • Oversee development of new SDK generators for e.g., C#, PHP, Rust, Swift, Elixir, etc.

  • Drive our core “compiler” design to support many programming languages, library features, and edge cases.

  • Scale our SDK build platform to manage hundreds of concurrent customer builds.

  • Partner with OpenAI, Anthropic, et al on the design of future APIs and their optimal support in SDKs.

  • Act as editor-in-chief of our technical documentation.

  • Mentor high-slope engineers toward rapid career growth.

  • Source, interview, and close some of the best engineers you’ve ever worked with.

Who you are

  • You’ve managed a high-performing engineering team in an early- or growth-stage startup.

  • You’re hands-on: deeply technical, understand in detail what your team is working on, and like to give architecture and product guidance.

  • You’ve personally recruited engineers to join a team you manage.

  • You have 2+ years of engineering management experience and have managed more than one team.

  • You’ve worked on libraries, for example building a popular open source project or designing internal abstractions used across a company.

  • You’re interested in growing your management skills as the team scales over the next 2 years.

  • You’ve started something before: a business, a club, a nonprofit, a student org; anything that shows you’re a builder at heart.

Benefits

  • We offer competitive salary and generous equity grants.

  • Great healthcare coverage options (e.g., fully covered platinum plans).

  • Paid commuter benefits & similar.

  • Paid team lunch/meals during workdays.

  • Flexible PTO plus 3 weeks of company-wide vacation a year (2 weeks in December, 1 week at the end of the summer).

  • Flexible WFH and 1 month fully remote per year ("remote February").
