- Write unit and integration tests for critical business logic and data consistency scenarios.
Requirements
- 4+ years of commercial backend development experience, including practical experience with Go.
- Strong understanding of concurrent programming, goroutines, channels, context, and cancellation patterns.
- Experience with PostgreSQL, database migrations, transactions, and performance tuning.
- Experience with Kafka, RabbitMQ, NATS, or another message broker in production systems.
- Understanding of API design, authentication, validation, pagination, and error handling.
- Practical experience with Docker and Kubernetes-based deployments.
- Strong spoken English - Upper-Intermediate / Advanced level, B2+ or higher.
Nice to Have

- Experience with OpenTelemetry, Prometheus, Grafana, Loki, or similar observability tools.
