Go developer in backend services

Описания нет

• Design, build and maintain backend services in Go: clean, idiomatic, readable code
• Design gRPC and REST APIs, keep their contracts stable, and version them when they change
• Write efficient PostgreSQL queries, design schemas, and write safe, reversible migrations
• Use goroutines, channels and context correctly: no leaks, proper timeouts and cancellation
• Handle errors explicitly, with retries and idempotency where calls can repeat
• Write unit and integration tests for business logic and failure cases
• Add structured logging, metrics and health checks so problems can be seen and diagnosed
• Keep the services secure: validate input, authenticate callers, keep secrets out of code and logs
• Profile and optimize CPU, memory and database load when needed
• Write short technical docs for the APIs and services you own
• Review teammates' pull requests and keep the code consistent

• 1–3 years of commercial backend development in Go
• Built or maintained at least one production service in Go (REST or gRPC)

• Used Docker.
• Integrated a third-party API
• Used Git and pull requests in a team
• Go: goroutines, channels, context, error handling, standard library
