Senior Software Engineer CV Example
Architecture decisions, mentoring and cross-team delivery — the shift from writing code to multiplying it.
A senior engineer CV must show a different unit of work: not features shipped, but systems shaped and engineers multiplied. This example spends its strongest bullets on architecture calls, migrations led and people grown — with the measured outcomes that make each claim solid.
Why this CV works
- The migration story — pattern named, scale stated, downtime zero — is a complete senior-engineering narrative in one bullet.
- People outcomes (three promotions) are claimed with the same precision as technical ones.
- Cost, latency and reliability wins cover the three axes senior engineers are hired to move.
- The older role still earns its place with systems that lasted (a 4-year stable API).
The professional summary
Senior Software Engineer with 9 years, currently technical lead for a 6-engineer team building a multi-tenant SaaS billing platform (Java/Spring, AWS). Led the strangler-pattern migration of a 400K-LOC monolith into 12 services with zero customer-facing downtime, and mentors engineers of whom three have been promoted in two years.
State the team you lead, the system you own and the hardest technical transition you have driven. Titles vary between companies — scope is the universal signal.
Writing the work experience
Promote decisions over tasks: why event-driven, why strangler, what the trade-off was. Interviewers hire seniors for judgement, and judgement shows in choices.

Skills on this CV
ATS tips for Senior Software Engineers
- Include both "microservices" and "distributed systems" — senior ads split between them.
- Name AWS services individually (ECS, RDS, SQS); "AWS" alone under-matches infrastructure-heavy ads.
- "Technical leadership" and "mentoring" are filtered phrases for senior roles — use both verbatim.
ATS checks help identify potential compatibility issues, but employers and ATS platforms use different criteria — no template or score can guarantee an outcome.
Writing tips
- Zero-downtime, zero-breaking-change claims are memorable precisely because they are absolute — use them only when true.
- Attach a dollar figure to at least one decision; cost fluency is a senior differentiator.
- Show the "before" state honestly (18% change failure) — credible baselines make improvements believable.
Frequently asked questions
My title never said "senior" — can the CV still read senior?
Yes. Scope does the work: systems owned, reviews run, people grown. State those and let the reader draw the level.
How much architecture detail is too much?
One pattern name and one trade-off per story. Deep dives belong in the interview, not the CV.
Should I keep hands-on coding bullets?
Keep one or two — teams fear seniors who have stopped coding. The reconciliation engine bullet exists for exactly that reason.
