Software Engineer Resume Keywords: 150+ Terms Recruiters (2026)
Aman Gupta
Key takeaways
- ATS keywords come from the job description — this 150+ list is your starting palette; always match the exact terms in the specific JD.
- Keywords in your experience and project bullets outweigh the same words in a standalone skills list — place them in context.
- Use exact terms and spell out abbreviations once ("Amazon Web Services (AWS)"), because older parsers don't equate "AWS" and "Amazon Web Services" or "React" and "React.js."
- Match your keywords to your level — a fresher's set differs from a senior or staff engineer's.
You're mid-edit on your resume, the job description is open in another tab, and you want to know exactly which words to include so the ATS ranks you. This page is that list — 150+ software engineer resume keywords organised by category, plus how to place them so they actually count.
The right keywords for your resume always come from the specific job description — but this list is the palette to pull from, covering the languages, frameworks, databases, cloud, DevOps, and concepts recruiters and ATS systems search for. Below the lists, you'll find how to weave keywords in without stuffing, the terms candidates most often miss, and the keyword sets that change by experience level.

How to use this list
Don't paste the whole list into your resume — match it to the job description and place the terms in context. Three rules:
The JD wins. Use this list to recognise relevant terms, but the exact words to include are the ones in the posting you're applying to. Mirror its phrasing.
Context beats a list. A keyword inside an experience or project bullet ("Built REST APIs in Node.js…") scores higher than the same word in a standalone skills section, because it signals demonstrated, not just claimed, skill.
Only what you can defend. The ATS gets you the interview; the interview tests whether the skill is real. Don't list anything you can't speak to.

The keywords software engineers most often miss
Frequently missing keyword | Why it matters |
|---|---|
CI/CD | Named in most backend/full-stack JDs; candidates describe the work without the term |
System Design | Expected from mid+ engineers; often implied but not stated |
REST APIs / GraphQL | Candidates write "APIs" without the specific term the JD uses |
Unit Testing / TDD | Frequently done, rarely written down |
Microservices | Common in JDs; missing from resumes that describe the architecture generically |
How to weave keywords into bullet points (without stuffing)
The highest-scoring place for a keyword is inside a result-driven bullet. Use the Action + Metric + Impact pattern and let the keyword sit in context:
"Built and optimised REST APIs in Node.js, cutting p95 latency from 1.2s to 180ms."
"Containerised services with Docker and deployed to Kubernetes on AWS EKS, enabling zero-downtime releases."
"Designed a microservices architecture with Kafka message queues, scaling throughput 4×."
"Implemented CI/CD pipelines in GitHub Actions, reducing deployment time from 40 to 8 minutes."
"Wrote unit and integration tests (TDD), cutting production defects 30%."

Keywords by experience level
The terms that signal seniority change with your level — match the set to where you are.
Level | Emphasise |
|---|---|
Fresher / Junior | Languages, Data Structures, Algorithms, OOP, Git, REST APIs, a primary framework, basic SQL, one cloud, Agile |
Mid (3–5 yrs) | System Design, Microservices, CI/CD, Docker, Kubernetes, testing, message queues, performance optimisation, a deep framework + cloud |
Senior (5+ yrs) | Distributed Systems, Architecture, Scalability, Mentorship, Code Review, cross-team leadership, observability (Prometheus/Grafana/Datadog) |
Staff / Principal | Technical Strategy, Platform/Architecture ownership, System Design at scale, reliability (SLO/SLA), org-wide influence, technical mentorship |

Frequently asked questions
What are the best keywords for a software engineer resume?
The best keywords are the ones in the specific job description that genuinely match your experience — typically your programming languages, frameworks, databases, cloud platforms, and concepts like REST APIs, microservices, CI/CD, and system design. Use the JD as your source of truth and this list to recognise relevant terms.
Where should I put keywords on my resume?
Put your most important keywords inside your experience and project bullets, where the ATS weights them highest, and also in a clean skills section. Keywords in context (a real action and result) score higher than the same word sitting alone in a list.
How many keywords should a software engineer resume have?
There's no fixed number — include every relevant term from the job description that you can genuinely back up, placed naturally. Quality and exact-match matter far more than volume, and stuffing in keywords you can't defend backfires in both the ATS check and the interview.
Should I write "AWS" or "Amazon Web Services"?
Use both at least once — write "Amazon Web Services (AWS)" the first time, then "AWS" after. Some ATS systems search for the full term, others for the abbreviation, and older parsers don't equate the two. The same applies to "React" vs "React.js" and "ML" vs "machine learning."
Do soft-skill keywords help on a software engineer resume?
Only a little, and only in context. ATS scoring favours hard, technical skills; soft skills like "collaboration" or "mentorship" carry weight when demonstrated inside a bullet ("Mentored 3 junior engineers…"), not when listed as standalone claims.
How do I find the right keywords for a specific job?
Read the job description and list every skill, tool, and qualification it names; on Naukri, also check the "Key Skills" tags at the bottom. Then match those terms to your resume. An ATS checker automates this — paste the JD and it shows the matched and missing keywords instantly.
