Senior Golang Backend Engineer

We’re looking for a Senior-level / Senior+ Go Backend Engineer to build and operate high-throughput microservices. You’ll focus on performance, reliability, and clean design, using profilers and remote debugging to keep services fast and stable in production.

What you’ll do

• Design, build, and operate Go microservices for high-load, low-latency workloads (REST/gRPC).
• Profile and optimize code (CPU/memory/trace) using pprof, go tool trace, flame graphs.
• Perform remote debugging in real environments (Delve, VS Code Remote, port-forwarding).
• Write robust unit tests (table-driven) and meaningful benchmarks (go test -bench), keep coverage healthy.
• Integrate with data/streaming systems: RabbitMQ, Redis, MongoDB, ClickHouse.
• Ship via GitLab CI/CD (pipelines, runners, Docker images); automate quality gates.
• Contribute to service observability (metrics/logging/tracing; Prometheus/OpenTelemetry/Jaeger).
• Apply design patterns and clean architecture; participate in code/design reviews.

Must-have

• 8+ years of backend experience, 6+ with Go in production.
• Strong Go fundamentals: concurrency (goroutines, channels, context, sync), profiling, performance tuning.
• Hands-on microservices experience (Docker).
• Remote debugging proficiency (Delve) and production troubleshooting skills.
• Solid testing discipline (unit tests, benchmarks) and GitLab CI/CD experience.
• Practical knowledge of REST/gRPC and at least one of RabbitMQ/Redis/MongoDB/ClickHouse.
• Familiarity with design patterns, SOLID/clean architecture, idiomatic Go.
• Very good English Skills (speaking, listening, reading and writing skills)

Nice to have

• Telecom Protocol Knowledge (SMPP, SS7)
• ClickHouse performance tuning; Redis as cache/rate-limit/locks; MongoDB schema design.
• Observability stacks (Prometheus, Grafana, OpenTelemetry, Jaeger, Loki).
