If you are applying for a Software Engineer role at any mid-size or large employer, your resume is almost certainly being parsed into a database before a human reads it — and then searched by a recruiter using specific terms. A recruiter filling a backend role searches for the language and the infrastructure. A hiring manager reading the shortlist looks for whether you have shipped something at the scale they operate at.
The rule that matters: use the words the employer used, wherever they are genuinely true of your experience. Not more of them, not louder — just the right ones, placed where a reader would expect them.
The Software Engineer keywords recruiters actually search
These are grouped the way a resume is structured, so you can see where each type belongs. Pick the terms that describe work you have really done.
| Category | Terms to use where true |
|---|---|
| Languages | Python, JavaScript, TypeScript, Java, Go, C#, Ruby, Rust, Kotlin, Swift, SQL, Scala, PHP |
| Frameworks & runtimes | React, Node.js, Django, Spring Boot, FastAPI, .NET, Rails, Next.js, Express, GraphQL, gRPC, REST API |
| Infrastructure & cloud | AWS, Azure, Google Cloud Platform (GCP), Docker, Kubernetes, Terraform, CI/CD, Jenkins, GitHub Actions, Kafka, Redis, PostgreSQL, MongoDB, Elasticsearch |
| Practices | Test-driven development (TDD), Code review, Microservices, Distributed systems, System design, Observability, Unit testing, Integration testing, Agile, Pair programming, On-call, Incident response |
| Action verbs | Built, Shipped, Migrated, Refactored, Optimized, Scaled, Automated, Instrumented, Debugged, Designed |
Do not paste this table into your resume. A block of comma-separated terms with no evidence behind it reads as padding to the recruiter who opens your file, and it does not reliably help you rank. Choose the fifteen or twenty terms you can defend in an interview.
Where to put them
- Your title line. If your official title differs from the posting's, put the recognisable version alongside it — for example Member of Technical Staff (Software Engineer).
- A two-line summary. Name your function, your level, and the two or three capabilities the posting leads with.
- Inside your experience bullets. This is where the important terms belong, attached to a result. A skill evidenced by an outcome beats the same skill in a list.
- A compact skills section. Group by category, keep it to one or two lines per group, and only include what you would be comfortable being asked about.
- A certifications section. Cloud certifications carry real weight in infrastructure-adjacent roles; elsewhere, shipped work matters more than credentials.
Three bullets, before and after
The most common problem on a resume is not missing keywords — it is keywords buried inside a description of duties. These rewrites keep the same facts and change what the reader takes away.
What Software Engineer resumes get wrong
Works
- Put the stack in the bullet, not only in a skills list
- Give scale — requests, users, data volume, latency
- Name the cloud provider and the orchestration layer
- Say what you owned versus contributed to
- Link a GitHub or portfolio in the contact block
Costs you
- A 40-item skills wall with no evidence
- Rating your own skills out of five with progress bars
- Listing a language you used once in a bootcamp module
- "Worked on" as the verb for everything you did
- Two-column layouts that break the parser
Certifications and credentials
Certifications matter less here than in most fields, with one exception: infrastructure and platform roles. AWS Certified Solutions Architect, AWS Certified Developer, Azure Administrator / Developer Associate, Google Professional Cloud Architect, and Certified Kubernetes Administrator (CKA) do get searched. For product engineering roles, shipped systems and a public repository generally carry more weight than any certificate.
Check yours against the actual posting
A generic keyword list gets you most of the way. The last stretch is specific to the job you are applying for — every Software Engineer posting emphasises a different subset, and the requirements that matter most are often buried in the middle paragraphs where people skim. Paste the job description and your resume into our free ATS scanner and it will pull the meaningful requirements out of the posting and show you which ones your resume evidences and which it does not. No sign-up, no credit card.
Frequently asked questions
Should I list every language I have touched?
No. List what you would be comfortable being interviewed in. A recruiter search matches the term either way, but an engineer asking you about a language on your resume that you barely know is a fast way to lose the interview.
How long should an engineering resume be?
One page under roughly eight years of experience, two beyond. Depth on your last two roles matters far more than completeness on the first two.
Do I need a separate skills section?
Yes, but keep it compact and grouped — languages, infrastructure, tools. It exists so a keyword search hits, and so a reader can scan your stack in two seconds. The evidence lives in your bullets.
Does GitHub help with the ATS?
The system does not crawl it, but the link is in your parsed profile and humans do click it. A pinned repo with a readable README is worth more than three extra resume bullets.
