You will work closely with DevOps, QA, and frontend teams to ensure high availability, scalability, and maintainability of our services.

REQUIREMENTS:

• 5+ years of backend development experience, including 2+ years in a microservices environment.
• Strong hands-on experience with .NET Core (C#) and PostgreSQL.
• Experience with distributed tracing, metrics, and log aggregation tools (e.g., Jaeger, Prometheus, Loki, Grafana).
• Deep understanding of REST, gRPC, and asynchronous messaging patterns (e.g., Kafka, RabbitMQ).
• Familiarity with Kubernetes, Docker, and container-based deployments.
• Understanding of software performance profiling, benchmarking, and optimization.
• Strong grasp of service resilience patterns: timeouts, retries, bulkheads, circuit breakers.

• Collaborate with QA to improve testability and traceability in a distributed system.
• Participate in architecture reviews and contribute to best practices for microservices at scale.
• Maintain CI/CD integration pipelines and ensure backend services deploy reliably.
• Troubleshoot and debug production issues using logs, traces, metrics, and profiling tools.
