Must-have skills for a Senior Backend / Microservices Engineer (owner-level)

Production microservices ownership (not just “worked on”)

• Has owned at least 1–2 services end-to-end (design → build → deploy → on-call → incident fixes → scaling)

• Comfortable with service boundaries, APIs, versioning, backward compatibility, SLAs/SLOs

System design & architecture (senior bar)

• Can design systems with tradeoffs: latency, throughput, cost, reliability

• Patterns: idempotency, retries, timeouts, circuit breakers, async workflows, queues, eventual consistency

• Data design: relational vs NoSQL, caching, indexing, migrations, multi-tenant considerations (if relevant)

Strong debugging & problem-solving in real-world scenarios

• Can take an ambiguous production issue and drive it to resolution

• Uses a structured approach: reproduce → isolate → instrument → hypothesis → validate → fix → prevent

Linux fundamentals (practical, daily-use)

• Confident with commands/tools like: ps/top/htop, journalctl, systemctl, netstat/ss, lsof, curl, grep/sed/awk, strace (bonus), log parsing

• Understands networking basics (DNS, TLS, ports, timeouts)

Docker + container runtime competence

• Can explain Dockerfiles, layers, multi-stage builds, image size/security

• Debug containers: env vars, volumes, entrypoints, networking, resource limits

Observability / logging / diagnostics

• Strong in structured logging, correlation IDs, trace context

• Metrics + tracing + logs as a system

• Datadog experience is a must-have , or a very credible equivalent (Prometheus/Grafana + OpenTelemetry + ELK) with proof they can ramp fast

Platform maturity

• CI/CD, release processes, rollback strategies

• Basic security and reliability hygiene (secrets mgmt, least privilege, rate limiting)
