Backend Engineer resume example
Backend engineering resumes reward specificity about the systems you've owned — the API surface, the data-store choice, the consistency model, and the scale numbers (requests/sec, row count, concurrency). 'Wrote backend services in Python' is invisible; 'Owned billing API at 8k req/sec, P99 85ms across a 6-shard Postgres-Citus cluster' is a bullet a staff BE recognizes in one line. Distinguish platform/infra work (shared services, observability, deploy infrastructure) from product-surface work (feature APIs that ship with the UI) — they're different specialties inside the same title.
How to write a strong backend engineer resume
- 1Name the stack with versions: 'Go 1.22, Postgres 16, Kafka 3.6, gRPC with protobuf-3'. Versions signal recency and distinguish maintenance from greenfield work.
- 2Report scale honestly: request/sec, database row count, concurrent connections, Kafka topic throughput. '1M rows' beats 'large dataset'.
- 3For distributed systems work: name the consistency model. Strongly consistent, eventually consistent, CRDT-based — hiring managers screen on this.
- 4Call out reliability: SLO/SLA numbers, incident response, runbook ownership. On-call frequency and MTTA/MTTR are fair game.
- 5Platform vs surface: 'built the internal auth library adopted by 28 services' is different from 'built the accounts API for the web app'. Both are valid; don't conflate them.
Sample experience bullets for backend engineers
Copy these as a starting point and adapt with your own numbers. Every bullet is written to read well in an ATS and on a recruiter skim.
- ▸Owned billing API serving 8k req/sec at P99 85ms across a 6-shard Postgres-Citus cluster (Go 1.22, gRPC); cut tail latency 340ms → 85ms via read-replica routing + query-plan tuning.
- ▸Rebuilt authentication as a gRPC-only module adopted by 28 downstream services (Go + Redis + Postgres); reduced inter-service auth overhead from 12ms to 3ms average at 99th percentile.
- ▸Designed and shipped an event-sourced audit log (Kafka 3.6 + ScyllaDB) processing 220k events/sec with at-least-once semantics and idempotent downstream consumers.
- ▸On-call rotation for 4 critical services; personal MTTA under 4 minutes, MTTR under 30 minutes across 2024. Authored 6 runbooks adopted team-wide.
