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.

Head of Engineering, iOS

Sully Ai · US - Remote

About Us
At Sully.ai, We’re Building the Most Impactful Healthcare Company on Earth

We believe that access to a great doctor is a basic human right. Today, that’s not a reality. Delays, misdiagnoses, administrative chaos, and burnout plague the system.

Our Mission: One Human, One Doctor. We build AI teammates that augment clinicians — scribes, nurses, receptionists, translators — all powered by our own world-class models and deployed in real-world care.

About the Role

  • We are seeking a Head of Engineering, iOS to own and scale our iOS mobile platform. You will lead end-to-end engineering execution for our iOS app, driving step-function improvements in performance, reliability, and user experience while establishing technical excellence across the mobile stack.

Key Responsibilities

  • Own end-to-end engineering execution for iOS, from architecture and roadmap through delivery and reliability.

  • Drive step-function performance improvements, targeting at least 50% reductions in app launch time, memory usage, and crash rates.

  • Design and operate robust observability, metrics, and automated testing systems to ensure consistent performance at scale.

  • Lead iOS execution rituals including daily and weekly standups, backlog ownership in Linear, and tight cross-functional coordination with Product, Design, and Backend teams.

  • Translate product goals into clear dependencies, timelines, and deliverables to keep teams unblocked and shipping.

  • Drive mobile EHR integration excellence, ensuring seamless integration with Epic Haiku, Epic HyperSpace, and other mobile EHR platforms.

Hard Requirements

  • Founder-level ownership mindset. You operate like the business depends on your decisions and execution.

  • Senior, hands-on iOS engineering ability. You actively design systems, write and review production Swift code, and set the technical bar by example.

  • Deep iOS platform expertise. 7+ years of iOS development with Swift/SwiftUI, UIKit, and modern iOS architectures. Experience shipping consumer-grade iOS apps to the App Store at scale.

  • Experience in high-intensity environments such as YC-backed startups, early-stage companies, or zero-to-one teams where speed and judgment matter.

  • Mobile leadership experience. You've led iOS teams (3+ engineers) and own mobile engineering processes, release management, and cross-platform coordination.

  • Comfort with ambiguity. You turn incomplete product direction into clear technical plans and ship without heavy process.

  • Bias toward leverage and simplicity. You choose durable solutions and know when to optimize versus when to ship.

Key Results (First 90 Days)

  • Take full ownership of iOS engineering. Establish yourself as the DRI for all iOS architecture, quality, and delivery decisions.

  • Ensure end-to-end observability and alerting for core iOS workflows including note generation, medical assistant features, and EHR sync.

  • Define key performance, reliability, and quality metrics for the iOS app (crash-free rate, memory usage, app launch time, user satisfaction scores).

  • Identify and ship at least one high-impact improvement — whether performance optimization, memory leak fix, or critical user experience enhancement.

  • Establish execution cadence, priorities, and quality standards including iOS release process, QA workflows, and automated testing infrastructure.

  • Audit and improve iOS technical debt including architecture issues, memory leaks, and automation testing setup.
