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.

As enterprise adoption of AI accelerates, OpenRouter sits at the center of how organizations operationalize LLMs across research, product, and production workloads.

About the Role

We're hiring our first Security Engineer to own the process of safeguarding our systems, infrastructure, applications, and data. As the first security hire, you will build out our security operations and vulnerability management process for our AI gateway platform. You'll implement programs, run tooling, ship security fixes, and drive remediation across our stack. You’ll be responsible for all aspects of ensuring the security of our platform and users. This isn't a compliance paperwork role; it's a hands-on security position with direct impact on how we protect millions of API requests daily. You'll work closely with engineering and senior leadership to ship security improvements that actually matter.

What You'll Do

  • Deploy and operate vulnerability scanning across our cloud infrastructure. Triage findings and drive remediation with engineering teams.

  • Lead security assessments for internal and customer security needs (e.g. SOC 2 Type II, ISO 27001, HIPAA audits).

  • Maintain vulnerability and remediation documentation for auditors.

  • Act as a liaison between product, engineering, compliance, and GTM to guide and prioritize the right security investments.

  • Perform penetration tests, tabletop exercises, DR testing, and incident response.

  • Manage endpoint security tooling as we scale; conduct audit log reviews and maintain visibility across our stack.

About You

  • 3-5+ years in security engineering or operations.

  • Deep knowledge of cloud security and expertise in operating in a cloud-hosted environment.

  • Comfortable in compliance-heavy environments (SOC 2, ISO 27001, HIPAA).

  • Strong experience with SIEM platforms (Splunk, Elastic, Panther) and vulnerability scanners (e.g. Qualys, Tenable, Rapid7).

  • AI-forward with hands-on experience adopting, leveraging, and integrating AI tools.

  • Startup mindset; you thrive building programs from the ground up and not just inheriting existing playbooks.

  • Pragmatic and business-oriented, able to balance security rigor and business speed.

  • Ability to communicate risk and technical ideas clearly to both technical and non-technical audiences.

Bonus Points

  • Experience with AI/ML infrastructure or inference platforms.

  • Automation and scripting with Python.

  • Healthcare data handling or BAA compliance experience.
