Software Engineer Resume Keywords (Technical Skills Keywords + ATS Examples)
Use this page to align your skills section with how engineering managers write reqs: explicit languages, runtime, data, and quality practices. Pair each skill with proof in your experience bullets.
Languages & runtime
Primary stack signals.
- TypeScript
- JavaScript
- Python
- Go
- Java
- Kotlin
- C#
- Rust
- memory management
- concurrency
Weak: Programming languages
Strong: TypeScript for services and shared types across API clients; reduced integration bugs.
Weak: Go
Strong: Go services for high-concurrency workers with structured concurrency patterns.
Frameworks & API styles
Match front/back focus.
- React
- Next.js
- Node.js
- Express
- Spring Boot
- Django
- FastAPI
- GraphQL
- OpenAPI
- protobuf
Weak: Framework experience
Strong: Next.js App Router with server components for SEO-critical pages.
Weak: APIs
Strong: GraphQL federation for domain boundaries with resolver-level caching.
Datastores & caching
Expected for most SWE roles.
- PostgreSQL
- MySQL
- Redis
- DynamoDB
- Elasticsearch
- index design
- transactions
- migrations
- ORM
- query optimization
Weak: Databases
Strong: PostgreSQL with partial indexes and covering indexes for hot reporting queries.
Weak: Caching
Strong: Redis for idempotency keys and session offload reducing DB load.
Testing & quality practices
Depth marker for seniority.
- unit tests
- integration tests
- contract tests
- TDD
- test coverage
- mocking
- testcontainers
- load testing
- chaos engineering
- static analysis
Weak: Testing
Strong: Integration tests around payment edge cases preventing recurring production bugs.
Weak: Quality
Strong: Static analysis in CI blocking merges on new critical issues.
Cloud, CI/CD & observability
Operational skills.
- AWS
- GCP
- Azure
- Docker
- Kubernetes
- Terraform
- GitHub Actions
- CI/CD
- Prometheus
- OpenTelemetry
Weak: AWS
Strong: ECS services with autoscaling tied to custom metrics.
Weak: Observability
Strong: OpenTelemetry traces linking API to downstream DB calls for latency debugging.
Where to use these keywords (ATS + readability)
Skills
Order by relevance to target role; repeat top skills in experience for ATS reinforcement.
Experience bullets
Attach metrics to skill usage: latency, uptime, cost, defect rate.
Skills
Separate ‘proficient’ vs ‘exposure’ if needed—but be honest.
Summary
One line on specialty: backend APIs, frontend perf, infra, etc.
Experience bullets
Mention scale: RPS, QPS, GB/day, team size—skills without scope look generic.
Common mistakes
- Listing 40 skills—signals breadth without depth.
- Framework names without production experience.
- Omitting testing/CI when job stresses quality.
- Ignoring cloud when posting is cloud-native.
