Software Engineer Resume Keywords (2026)

Top 30 software engineer resume keywords explained

Each keyword below includes what it means for ATS and how to use it on a resume. Copy only terms you can defend in an interview.

1. Software engineer

   Mirror the exact title from the posting in your headline and recent roles when true. ATS and recruiters literal-match job titles before stack depth.

2. Software developer

   Many JDs use developer interchangeably with engineer. If the posting says software developer, use that phrasing once in summary or skills so parsers do not miss you.

3. TypeScript

   Put TypeScript in Skills and at least one shipped bullet (typed APIs, React modules, fewer runtime errors). Listing it alone without proof looks shallow.

4. JavaScript

   Still a baseline filter for web and full-stack roles. Pair JS with frameworks you used in production, not every library you tried once.

5. Java

   Enterprise and backend postings still filter heavily on Java. Mention versioning context (services, Spring, JVM tuning) when the JD expects it.

6. Python

   Use Python when the role includes scripting, services, or data-adjacent work. Tie it to automation, APIs, or tools you actually maintained.

7. C++

   High-signal for systems, performance, and embedded-leaning SWE roles. Only claim C++ if you can discuss memory, concurrency, or production systems.

8. SQL

   Almost every product SWE posting expects SQL. Show joins, indexes, or query tuning in Experience — not only “databases” in Skills.

9. HTML/CSS

   Still scanned for frontend-adjacent SWE roles. Use when you shipped UI; skip for pure backend/infrastructure JDs to avoid scatter.

10. React

    Name React next to features you owned (performance, a11y, state). ATS matches the word; hiring managers expect a metric or release outcome.

11. Node.js

    Common Node/Express/Fastify filter for API work. Pair with latency, throughput, or reliability results in bullets.

12. REST APIs

    Core SWE vocabulary. Prefer “designed/versioned REST APIs” with consumers, contracts, or SLA impact over a bare skills chip.

13. PostgreSQL

    Literal ATS match for relational work. Cite schema, indexes, migrations, or p95 query improvements when accurate.

14. Oracle

    Still appears in enterprise postings. Include Oracle only with module or workload context (queries, PL/SQL, migrations)—not as filler.

15. AWS

    Cloud is a top filter. Name the services you operated (ECS, Lambda, RDS) and what improved—cost, uptime, or deploy speed.

16. Docker

    Signals packaging and deploy fluency. Use with CI, local/prod parity, or image size/security hardening—not “familiar with containers.”

17. CI/CD

    Delivery keyword for modern SWE screens. Show pipeline ownership: tests, staged rollouts, or shorter deploy times.

18. System design

    Seniority signal. Put design tradeoffs in bullets (boundaries, scaling, failure modes)—not only in a summary buzzword.

19. Microservices

    Use when you owned service boundaries, contracts, or migrations. Vague “worked on microservices” without scope fails screens.

20. Distributed systems

    Enterprise and platform JDs often use this phrase. Prove it with messaging, consistency, retries, or multi-service ownership.

21. Unit testing

    Quality keyword ATS and eng managers expect. Cite coverage gains, fewer regressions, or frameworks you used in CI.

22. Code optimization

    Indeed and many JDs still use this wording. Prefer specific wins: CPU/memory, latency, payload size, or algorithm changes with numbers.

23. JIRA

    Common collaboration/tool filter. Mention JIRA when you ran backlogs, bugs, or releases—not as empty Agile theater.

24. Git

    Baseline VCS signal. Reinforce with code review, branching, or release flow language if the posting emphasizes process.

25. Agile

    Process keyword on most SWE boards. Back it with sprint delivery, refinement, or ship cadence—not “Agile methodology” alone.

26. Technical documentation

    Shows you can leave systems runnable for the next engineer. Cite ADRs, runbooks, API docs, or onboarding guides you authored.

27. Project management

    Appears on generalist SWE and tech-lead hybrid roles. Frame as scoping, sequencing, and shipping—not PMP jargon unless required.

28. Cloud computing

    Broad ATS phrase some enterprise parsers still use. Pair the generic term with a concrete provider/service you ran.

29. Observability

    Modern reliability keyword (metrics, logs, traces). Tie to incidents shortened, SLOs, or tooling like Datadog/OpenTelemetry.

30. Code review

    Team quality signal. Mention review ownership, standards you enforced, or defect escape rate drops when true.
