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.

Senior/Staff Platform Engineer (Compute Migration)

Heartflowinc · San Francisco, California

Heartflow is a medical technology company advancing the diagnosis and management of coronary artery disease, the #1 cause of death worldwide, using cutting-edge technology. The flagship product—an AI-driven, non-invasive cardiac test supported by the ACC/AHA Chest Pain Guidelines called the Heartflow FFRCT Analysis—provides a color-coded, 3D model of a patient’s coronary arteries indicating the impact blockages have on blood flow to the heart. Heartflow is the first AI-driven non-invasive integrated heart care solution across the CCTA pathway that helps clinicians identify stenoses in the coronary arteries (RoadMap™Analysis), assess coronary blood flow (FFRCT Analysis), and characterize and quantify coronary atherosclerosis (Plaque Analysis). Our pipeline of products is growing and so is our team; join us in helping to revolutionize precision heartcare.

Heartflow is a publicly traded company (HTFL) that has received international recognition for exceptional strides in healthcare innovation, is supported by medical societies around the world, cleared for use in the US, UK, Europe, Japan and Canada, and has been used for more than 500,000 patients worldwide.  

Heartflow is transforming cardiovascular care with cutting-edge, non-invasive technology. We are launching a massive Platform Modernization initiative to power the next generation of our life-saving medical products.

Are you a platform engineer passionate about cloud-native technologies and large-scale migrations? Do you thrive on solving complex compute challenges by leveraging the power of Kubernetes? Join our dynamic Infrastructure Platform team and help us drive a critical initiative to modernize our event-driven serverless and containerized workflows!

Job Responsibilities

We're looking for a Senior/Staff Platform Engineer, specializing in Compute Migration, to help with the strategic effort to migrate all of our existing AWS Lambda and ECS-based workloads to our next-generation Kubernetes platform. This is a high-impact role where you will design, implement, and govern the transition of business-critical, event-based workflows, ensuring they are optimized for performance, cost, reliability, and security within our K8s environment.

This role requires expertise in both current (Lambda, ECS) and target (Kubernetes) compute architectures, as well as a strong focus on automation and developer experience.

  • Develop robust, scalable, and automated solutions for running event-driven, serverless-like workflows on Kubernetes, potentially utilizing technologies like KEDA or similar cloud-native tools.
  • Use Terraform/Terragrunt and Helm to build and manage the necessary underlying Kubernetes infrastructure, networking, and deployment tooling. 
  • Partner closely with engineering teams to understand their unique workload requirements, provide consultation on re-platforming best practices, and develop standardized tools (e.g., CI/CD pipelines) for easy migration and deployment.
  • Benchmark migrated services, optimize resource requests/limits, and implement advanced observability (monitoring, logging, tracing) solutions to ensure parity or improvement in service SLOs.
  • Establish best practices, guardrails, and documentation for running event-based compute on Kubernetes to ensure a smooth transition and sustainable operation post-migration.

Required Qualifications

  • 3+ years of experience in Platform, Infrastructure, or DevOps Engineering roles, with significant time spent on large-scale compute migrations.
  • Proficiency in Kubernetes (design, deployment, operations, networking, security, and scaling).
  • Hands-on experience with AWS compute services, particularly AWS Lambda and ECS/Fargate, and a clear understanding of their operational models and scaling behaviors.
  • Proven experience migrating production workloads from traditional cloud compute (VMs, Lambdas, ECS) to Kubernetes.
  • Strong background in Infrastructure as Code (IaC), specifically Terraform.
  • Proficiency with containerization technologies (Docker) and modern CI/CD practices.
  • Excellent communication, documentation, and technical leadership skills, with the ability to influence technical decisions across multiple teams.

Nice-to-Have

  • Experience working in and/or migrating to workflow orchestartion tools.
  • Experience with Python or Go for tooling development and automation.
