Strong Action Verbs for a Software Engineer Resume
Recruiters skim each bullet for two seconds, and the first word decides whether they keep reading. 'Responsible for' and 'worked on' say nothing; engineering hiring managers respond to verbs that show you built, improved or rescued something. Below is a verb bank organized by the kind of impact you drove — then a before/after rewrite you can copy.
The template opens straight in your workspace — even if you have never saved it before.

Before / after: see the difference
Weak: "Responsible for working on the payments microservice and fixing bugs." Strong: "Rebuilt payments microservice retry logic, cutting failed transactions 42% and eliminating a weekly on-call page." Why it works: 'Rebuilt' and 'cut' carry the sentence; the numbers prove scale. The 'responsible for' version hides both.
Frequently asked questions
- How many times can I repeat an action verb?
- Never twice in the same role. Twelve bullets starting with 'Developed' reads like one bullet. Keep the bank above open while you edit — KlarCV's bullet assistant flags repeated openers automatically and suggests alternatives that fit the sentence.
- Can I check my resume against these rules for free?
- Yes. Paste your resume text (or import the file) into KlarCV and the built-in ATS check scores parseability, keyword match and bullet strength — with concrete fix suggestions for each issue it finds. No account required during the test phase.
