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.

Software Engineer: Full Stack

Thatch · Remote (US); San Francisco, California, United States

About the role

Thatch is rewiring how health benefits work. We build software that powers employer-funded coverage and gives employees real control over how they use their benefits.

We’re looking for a Full Stack Software Engineer to own broad product surfaces, from concept to production. You’ll build across the frontend and backend systems that power onboarding, benefits management, and payments. This work touches real money and real healthcare decisions. Correctness and reliability matter, but so does making the experience feel simple for the people using it.

We organize engineering around the people we serve: members, employers, and partners, so teams own end-to-end experiences and ship with speed and accountability.

What you'll do

  • Take ownership of meaningful product areas from idea through production.
  • Ship quickly, but never at the expense of correctness or long-term maintainability.
  • Contribute across the stack, from user-facing interfaces to backend services.
  • Translate real user and business needs into clear, pragmatic technical solutions.
  • Set and uphold a high bar for code quality, system design, and product polish.
  • Take responsibility for production systems, including reliability, debugging, and continuous improvement. 

What we are looking for

  • Experience building and shipping production web applications across the stack.
  • Strong product judgment and comfort working through ambiguity.
  • Ability to reason about complex systems and business logic.
  • Familiarity with modern engineering tools and frameworks.
  • A track record of ownership, cross-functional collaboration, and good technical decision-making.

We hire engineers across multiple levels and care most about the scope you’ve owned, the impact you’ve had, and how you make decisions.

Tools and tech stack

  • Ruby on Rails for backend systems.
  • React and TailwindCSS for the frontend.
  • Small amounts of Python and backend JavaScript where appropriate. 

Prior Ruby experience is helpful but not required. We care far more about how you think than which language you know.

Experience that stands out

  • Work in healthcare, finance, or other complex or regulated domains.
  • Experience with HR, payroll, payments, or partner-facing systems.
  • Ownership of systems with real operational or financial impact.

How we work

  • We move quickly and bias toward action.
  • We ship early, learn from real usage, and iterate.
  • We operate with trust, ownership, and high empathy.
  • We value clarity over ceremony and quality over shortcuts.

What to expect

We aim to keep the process thoughtful, rigorous, and efficient. Most candidates complete it within three weeks. You can expect:

  • An initial conversation with a recruiter.
  • A collaborative pair programming session.
  • A systems design interview and a separate conversation with one of our engineers about how we work together.
  • A final conversation with engineering and company leadership.
