Resume Guide · Engineering
The Software Engineer resume, decoded.
Software engineering resumes need the right mix of technical skills, project impact, and ATS-friendly formatting. Generic resumes miss role-specific keywords like CI/CD, microservices, or system design that recruiters filter for.

- Plain single-column header — Workday parses name, title, and contact cleanly.
- Metric + technology + scale in one line. This is what rankers reward.
- Exact keyword matches: "CI/CD" and "React", not "modern tooling".
The problem
Where software engineer resumes die.
Before a recruiter ever sees your resume, parsing and ranking software decides whether they will. For software engineers, these are the failure points.
On the page
- 01Technical skills buried in paragraphs
- 02Missing framework/language keywords
- 03No quantified project impact
- 04Over-designed layouts that break ATS parsing
Inside the ATS
- 05Tables and columns break Workday parsing
- 06Skills listed without context get lower ranking
- 07Missing "years of experience" pattern matching
The fix
Same experience. Different resume.
Ranking algorithms reward specificity: metrics, named tools, scale. Here is the same line from a software engineer resume, before and after.
Before
Worked on backend APIs and improved performance.
After
Reduced API p95 latency by 40% by rewriting the caching layer with Redis, serving 2M requests/day.
Before
Responsible for frontend development using modern frameworks.
After
Built a React analytics dashboard used by 10K daily users, cutting support tickets 25%.
- Lead with impact: "Reduced API latency by 40%" not "Worked on APIs"
- List technologies in context: "Built React dashboard serving 10K daily users"
- Use standard sections: Experience, Skills, Education — not creative alternatives
The vocabulary
The words the machine listens for.
These are the exact terms ATS filters scan software engineer applications for. If a keyword genuinely describes your experience, it belongs on the page — verbatim.

Filters match exact strings. Write “JavaScript”, not a synonym — and keep abbreviations next to their expansions.
The product
Rejectly reads your resume the way the machine does. Then fixes it.

Still sending the same resume to every job?
Every job has different keywords, different ATS filters, different expectations. A tailored resume for each application is the difference between getting rejected and getting hired.
