Senior Backend Engineer

We’re looking for a Senior Backend Engineer who loves system design & architecture , writes high-performance Go , and knows how to take services from laptop to production with efficient, reliable deployments . You’ll also use AI coding tools to accelerate delivery while maintaining craftsmanship.

What you’ll do

• Own backend services end-to-end: design, implement, test, deploy, observe, and iterate.

• Lead architecture for new features and platforms (APIs, services, data flows, queues).

• Build robust Go services (REST/gRPC) with strong concurrency, reliability, and clarity.

• Design storage models and access patterns across Postgres (or similar), Redis caches, and object stores.

• Drive operational excellence : CI/CD, zero-downtime deploys, canary/blue-green, rollbacks.

• Make systems fast and cost-efficient via profiling (pprof), tracing, and capacity planning (P50/P95/P99).

• Champion security-by-default (authn/z, JWT/OAuth2, secrets, least privilege) and observability (logs/metrics/traces).

• Use AI tools (e.g., ChatGPT, Copilot) to draft code/tests/migrations, generate scaffolding, and accelerate root-cause analysis—while upholding code quality.

• Mentor engineers; review designs and PRs with empathy and high standards.

What you’ll bring

• 5–8+ years building production services; 3+ years with Go in performance-sensitive systems.

• Strong system design skills: domain modeling, API boundaries, microservice vs. modular monolith trade-offs.

• Deep understanding of deployment and runtime efficiency: containers (Docker), orchestration (Kubernetes or equivalents), CI/CD, build pipelines, and runtime tuning.

• Proficiency with transactions and data integrity; comfortable with migrations (Atlas, Flyway, Liquibase, or similar).

• Experience with gRPC/REST , streaming or async workloads (Kafka/NATS/SQS), and idempotent processing.

• Practical observability : Prometheus/Grafana, OpenTelemetry, structured logging.

• Solid testing discipline: unit, integration (testcontainers), contract tests; familiarity with feature flags.

• Comfort using AI tooling responsibly to speed up development without sacrificing maintainability.

Nice to have

• Distributed systems patterns (sagas, outbox, CQRS), rate limiting, and backpressure.

• Edge/CDN and web security basics (CSP, mTLS, WAF, Cloudflare).

• Experience with cost optimization and performance budgets in cloud environments.

• Hands-on with Railway/Heroku/Vercel or AWS/GCP/Azure primitives.

How we work

• Small, senior team with high ownership and strong code review culture.

• Pragmatic processes: ADRs for key decisions, lightweight RFCs, automated checks in CI.

• “Measure first” mindset: we ship, observe, and iterate quickly.
