Software Engineer resume keywords and example

Software engineering postings are unusually specific: they name languages, frameworks, cloud services and practices like testing and CI/CD, and recruiters search for those exact terms. Below are the keywords that repeat, a sample summary, skills grouped by type, and example bullets that show scope and impact at each level.

Updated 4 October 2026. Keyword research current as of July 2026, sourced from public ATS keyword guides, not Weydr's own usage data.

Software Engineer keywords that repeat in job postings

  • TypeScript / JavaScript
  • System Design
  • REST APIs
  • PostgreSQL
  • AWS
  • CI/CD
  • Testing
  • React

Only include the ones that are true for you. A keyword you can't back up in an interview costs more than it gains.

Sample professional summary

Backend-leaning software engineer with 4 years building TypeScript and Node.js services on AWS. Designs REST APIs and PostgreSQL data models, owns CI/CD pipelines and automated testing, and has scaled services to tens of thousands of requests per minute. Comfortable across the stack with React.

Illustrative example. Swap in your own years, domain, tools and results.

A tailored bullet, before and after

Worked on backend services and APIs.

Built and scaled REST APIs in TypeScript on AWS, adding CI/CD and automated test coverage that cut deploy incidents by 40%.

Example resume bullets by seniority

Illustrative examples: the companies, numbers and outcomes are made up to show the structure (action, scope, tool, result). Use your own real figures.

Entry level

  • Built 6 REST endpoints in TypeScript and Node.js for an internal billing service, with unit and integration tests that raised module coverage from 45% to 85%.
  • Fixed an N+1 query on a PostgreSQL-backed reports page, cutting p95 load time from 3.2s to 600ms.

Mid level

  • Moved a monolith's background jobs to a queue-based worker service on AWS ECS, removing the timeouts behind roughly 2 incidents a month.
  • Set up GitHub Actions CI/CD with preview environments for a 10-engineer team, reducing merge-to-production time from 2 days to under 1 hour.

Senior

  • Led system design for a multi-tenant event pipeline handling 50,000 events per minute, choosing Kafka and PostgreSQL partitioning and writing the design doc reviewed across 3 teams.
  • Mentored 4 engineers and introduced a code review checklist and on-call runbooks, after which production incidents fell by a third over two quarters.

Gaps candidates miss most

  • Specific language/framework versions and the actual cloud platform, not "cloud experience"
  • Testing and CI/CD practices, frequently assumed, rarely stated explicitly
  • System design experience without a scale metric attached (traffic, data volume, latency)

Common software engineer resume mistakes

  • A skills section listing 30 technologies with no sign of which ones you used in production.
  • Writing "cloud experience" instead of the provider and services (AWS ECS, GCP Cloud Run).
  • Describing what the system does instead of what you built or changed.
  • No scale or impact numbers: requests, data volume, latency, incident counts or deploy frequency.
  • Leaving out testing and CI/CD even when the posting asks for them.
