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.

Staff Software Engineer - Open Source

Signoz · India

About SigNoz

SigNoz is an open-source observability platform that helps modern engineering teams monitor, debug, and optimize their applications with deep visibility into metrics, traces, and logs — all in one place. We’re built natively on OpenTelemetry and offer both self-hosted and cloud options, so teams can run observability the way they want, without vendor lock-in.

We are growing fast and building core developer infra products.
And we are not fooling around:

  • 24,000+ GitHub stars

  • 500+ customers

  • 7,000+ members in our Slack community

Open source is not an afterthought at SigNoz — it’s what we set out to build. We believe the future of observability is open source, and that every team (not just the biggest companies) should have access to great tooling.

Role: Staff Software Engineer – Open Source

We’re looking for a Staff Software Engineer – Open Source who will own and elevate the SigNoz open-source experience end-to-end.

This role is for someone who loves building for developers, cares deeply about open source, and wants their work to directly impact how thousands of engineering teams observe and operate their systems.

Your north star: grow SigNoz OSS adoption

What you’ll work on

You will be responsible for making the SigNoz open-source experience smoother, more powerful, and easier to adopt:

  • Build an integration framework so developers can easily build, extend, and publish integrations with SigNoz

  • Improve the self-hosted setup & upgrade experience – from “read-the-docs-5-times” to “up in minutes”

  • Design and implement APIs, services, and core backend components in Go

  • Own a product roadmap focused on OSS: identify friction points, prioritize features, and ship improvements for open-source users

  • Create a marketplace of integrations: patterns, templates, examples, and tooling to help the community plug SigNoz into their stack

  • Instrument, measure, and iterate on OSS adoption metrics (deploys, upgrades, integrations used, etc.)

What will make you successful

  • 4–8 years of experience in backend engineering (Go preferred)

  • Strong understanding of concurrency, locks, channels, and performance in Go

  • Experience building backend systems, distributed systems, or developer tools

  • Loves open source – ideally with prior contributions to OSS projects (any size)

  • Ability to drive initiatives end-to-end: from problem discovery → design → implementation → rollout

  • Comfortable working in a high-ownership, fast-moving, remote-first environment

  • Strong communication skills – can write clear design docs and explain trade-offs

Nice-to-haves

  • Experience in observability (monitoring / logging / tracing)

  • Familiarity with OpenTelemetry and/or ClickHouse, Kafka, Kubernetes, etc.

  • Has been, or wants to be, a founder in B2B/devtools

Why you’ll love working at SigNoz

  • Work on a globally used open-source project that engineers actually love

  • Huge scope and ownership – your work directly shapes how teams adopt SigNoz

  • Collaborate with a small, senior, product-obsessed team

  • Remote-first, async-friendly culture

  • Opportunity to help define the future of open-source observability
