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.

AI Staff Software Engineer

Enhesa · Lisbon

Who We Are:

Enhesa is the leading provider of regulatory and sustainability intelligence worldwide. As a trusted partner, we empower the global business community with the insight to act today and prepare for tomorrow to create a more sustainable future - positively impacting our environment, our health, our safety, and our future. Navigating the fast-changing compliance and sustainability landscapes, we help them understand not just what they should do (first) but also how to do it. Both in their unique business and anywhere in the world. Now and in the future.

Our Mission:

  • Identify EHS requirements for the industry
  • Provide EHS compliance tools to companies
  • Advise companies in developing and implementing corporate EHS strategies

Enhesa’s core clients include Fortune 500 multinational companies. For more information, visit www.enhesa.com

As part of our highly dynamic team, we offer:

  • A competitive salary package & benefits with a flexible home-working policy
  • Work/life balance and a fast-paced and driven environment
  • Accountability and pride for your projects

We’re looking for a Staff Software Engineer who is equal parts builder and architect—someone who can take a feature from napkin sketch to production deployment and has strong opinions (loosely held) about how modern software should be built. You’ll work across the full stack: designing APIs, standing up infrastructure, wiring data pipelines, and shipping microservices that power AI-driven products.

This isn’t a role where you’ll be handed a spec and asked to implement it. You’ll be expected to challenge assumptions, propose better approaches, and move fast with the help of AI coding tools that are core to how we work.

What you'll do:

  • Design, build, and own microservices and APIs end-to-end—from data model to deployment pipeline to monitoring.
  • Architect and maintain CI/CD pipelines, container orchestration, and infrastructure-as-code across cloud environments (Azure preferred, AWS/GCP a plus).
  • Work hands-on with databases (relational and vector), message queues, and search infrastructure—configuring, tuning, and scaling them in production.
  • Collaborate with the AI team to integrate ML models and LLM-powered features into production services.
  • Champion engineering standards: code review culture, repository structure, testing strategies, and deployment practices.
  • Leverage AI-assisted development tools (Copilot, Claude Code, Cursor, etc.) to accelerate delivery—and help the team do the same.
  • Operate in Linux environments daily: scripting, debugging, managing services, and keeping systems healthy.

What We’re Looking For

The short version: a creative, resourceful engineer who builds real things, has seen what scales and what doesn’t, and gets genuinely excited about the new capabilities AI tooling unlocks.

  • Languages: Strong Python skills plus meaningful experience in at least one compiled/systems-level language (C#/.NET, C++, Go, Rust, or similar). You know when a scripting language isn’t enough.
  • Cloud & Infrastructure: Production experience with cloud platforms (Azure, AWS, or GCP). Comfortable with Terraform or Bicep, Kubernetes/AKS, and the general lifecycle of infrastructure-as-code.
  • Data & Storage: Hands-on work with SQL databases, Elasticsearch, vector databases (Qdrant, Pinecone, etc.), Kafka or equivalent message brokers. You’ve set them up, not just queried them.
  • Microservices & APIs: Deep experience designing, deploying, and maintaining distributed services. RESTful APIs, gRPC, event-driven patterns—you have opinions about when to use each.
  • CI/CD & DevOps: You’ve built pipelines (Bitbucket Pipelines, GitHub Actions, Azure DevOps, etc.) and care about how repos are structured, how tests run, and how code gets to production safely.
  • Linux: Daily-driver comfort. Shell scripting, process management, troubleshooting, system configuration.
  • AI Development Tools: Active user of AI coding assistants. You’re not just curious—you’ve integrated them into your workflow and can articulate what they’re good (and bad) at.

Bonus Points

  • Experience with MLflow, experiment tracking, or ML pipeline tooling.
  • Familiarity with Azure Kubernetes Service (AKS) and the Azure ecosystem specifically.
  • Background in NLP, RAG architectures, or LLM integration patterns.
  • Contributions to open-source projects or a visible portfolio of shipped work.
  • Experience in regulated industries (EHS, legal, financial, healthcare).

What You’ll Get

  • A seat on a small, high-impact AI team building products that matter at global scale.
  • Direct access to leadership—short feedback loops, real influence on architecture and direction.
  • A culture that treats AI tools as force multipliers, not novelties.
  • Competitive compensation, benefits, and flexibility.
  • The chance to help shape the engineering culture of a company in a transformative growth phase.

How We Work

Our tech stack includes Azure/AKS, Terraform, Bitbucket Pipelines, Kafka, Elasticsearch, Qdrant, SQL, and a multi-provider LLM strategy spanning OpenAI, Anthropic, and Google. We build AI microservices in Python and deploy them as containerized services. We use MLflow for experiment tracking and Splunk for observability.

We believe the best engineers are opinionated about their tools and pragmatic about their deadlines. If you have a strong point of view about how a codebase should be organized, how a deployment should work, or why a particular pattern is the right (or wrong) one—we want to hear it.
