What Recruiters Look For in a Software Engineer Resume
- Specific, current tech stack (languages, frameworks, cloud provider) that matches the job description's stack
- Quantified impact — latency, cost, uptime, throughput — not just "worked on" or "contributed to"
- Evidence of ownership: did you design it, ship it, and monitor it, or just write code someone else specified?
- A link to GitHub, a portfolio, or notable open-source contributions if you have them

Common Mistakes to Avoid
- Listing every framework you've ever touched instead of the ones you're actually proficient in
- Describing tasks instead of outcomes ("built an API" vs. "built an API that cut latency 80%")
- Skipping system design or scale details that senior recruiters specifically screen for
- Using a two-column or graphics-heavy template that ATS software can't parse the code/stack keywords from
Frequently Asked Questions
Should I include a GitHub link on my resume?
Yes, if it has real, maintained projects. A stale account with only forked repos and no commits in a year can actually hurt more than help — keep it current or leave it off.
How technical should the bullet points be?
Technical enough that another engineer could understand exactly what you built, but framed around impact. "Implemented a Redis-backed cache" is fine; "Implemented a Redis-backed cache that cut latency 80%" is better.
Do I need a different resume for each company?
You don't need a full rewrite, but reordering your top 2-3 bullets to match the specific role's stack and priorities (e.g. leading with scale for a high-traffic company, leading with 0-to-1 shipping for a startup) meaningfully improves response rates.
