Markdown, code blocks, and tables break ATS parsers.
A skills dump without proof of use looks like keyword stuffing.
"Kubernetes (K8s)" — capture both search variants.
Single column, standard fonts, no graphics. ATS-parseable.
"Built CI/CD pipeline using GitHub Actions, reducing deploy time by 60%."

Why a general AI assistant can't score your resume against one software engineer posting
Illustrative before and after pairs showing how keyword gaps cost candidates interviews
Built web applications and worked with APIs
Architected React + FastAPI platform serving 400k MAU; introduced GraphQL federation layer reducing mobile API payload 60% and cutting Time to Interactive from 4.1s to 1.8s
Worked on backend systems and improved performance
Redesigned PostgreSQL query pipeline with covering indexes and materialised views; eliminated N+1 queries and cut P95 latency from 820ms to 95ms for 2M daily active sessions
Set up cloud infrastructure and deployment processes
Migrated monolith to 8 Docker microservices on AWS (ECS + RDS + ElastiCache); GitHub Actions CI/CD pipeline ships to production 12× daily with automated rollback on error rate >0.5%

If the job says "RESTful APIs," don't write "REST services." ATS matches exact phrases.
Don't bury them in job descriptions only. A top-level Skills section helps ATS parse them faster.
"Improved API performance by 40%" scores higher than "improved API performance." Numbers signal real impact.
Stick to "Experience," "Education," "Skills," and "Projects." Custom headers confuse ATS parsers.
ATS systems often fail to parse multi-column layouts. Use a simple single-column format.
Don't just list "React" — say "Built customer-facing dashboard using React and Redux." Context boosts score.
AI resume tools can scan your resume against a specific job description in seconds — identifying missing keywords, weak bullet points, and ATS formatting issues that manual review often misses. Check your software engineer resume with the free ATS resume checker to see the gap against one specific posting.
AI tools compare your resume to the job description and give you a percentage match — so you know exactly where you stand before applying.
See which technical skills, frameworks, and tools appear in the job posting but are missing from your resume — the exact gaps costing you interviews.
Get a rewritten version of your resume with the missing keywords naturally integrated into your bullet points — ready to submit in one click.
The best AI tools for software engineer resumes go beyond keyword matching — they understand technical context, so "built a REST API" and "designed RESTful microservices" are treated differently.

Based on our analysis of 1,360 software engineer job postings from 72 companies, the most frequently requested terms are: Python (44.8% of postings), JavaScript (13.2%), React (21.1%), AWS (41.3%), and Docker (12.6%). Critical categories include programming languages, frontend frameworks, backend/API technologies, cloud and DevOps tools, databases, and methodologies (Agile, Scrum, TDD, System Design). Our full dataset shows which terms appear most in real postings rather than generic lists.
Do not build the resume as a language list. Name the systems work: scalability, distributed systems, system design and mentoring are the requirements these postings repeat most, and they need to read as things you did, in bullets, rather than sit in a skills row. Keep one column, and drop skill-rating graphics - they carry no text for a parser to read.
No applicant tracking system publishes a required score. In our count of 1,360 software engineer postings from 72 companies, the four most frequent requirements were not technologies: scalability 52.9%, mentoring 47.4%, distributed systems 47%, and system design 46.7%. Python, the most common language, appeared in 44.8%, and Agile or Scrum in 9.3%. A resume tuned to frameworks can miss most of what these postings actually ask for.
Yes. Paste your resume and a software engineering job description into the free ATS resume checker for a match score and the exact missing terms. The usual gap is architecture and mentoring vocabulary rather than another framework. No signup required.
