Remote Backend Engineer - Microservices & Distributed Systems (.NET Core)

Description:

• We are seeking a skilled and performance-minded Backend Engineer to support and evolve our distributed system of over 100 microservices, built primarily with .NET Core and PostgreSQL.
• The ideal candidate has deep experience in backend development, service-to-service communication, and infrastructure-level tools like Envoy Proxy, service mesh, and observability platforms.
• You will work closely with DevOps, QA, and frontend teams to ensure high availability, scalability, and maintainability of our services.
• Key responsibilities include designing, developing, and optimizing high-performance backend microservices using .NET Core/C#.
• You will integrate and manage Envoy Proxy for routing, load balancing, retries, and circuit breaking.
• Implement distributed tracing, logging, and metrics for observability using tools like OpenTelemetry, Prometheus, and Grafana.
• Optimize service-to-service communication and database access to reduce latency and improve throughput.
• Write scalable SQL queries and optimize PostgreSQL usage, indexing, and connection handling.
• Contribute to service discovery, dynamic routing, and rollout strategies (e.g., blue/green, canary).
• 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.

Requirements:

• You must have 5+ years of backend development experience, including 2+ years in a microservices environment.
• Strong hands-on experience with .NET Core (C#) and PostgreSQL is required.
• You should be proficient in Envoy Proxy, including configuration for routing, retries, circuit breakers, and observability.
• Experience with distributed tracing, metrics, and log aggregation tools (e.g., Jaeger, Prometheus, Loki, Grafana) is necessary.
• A deep understanding of REST, gRPC, and asynchronous messaging patterns (e.g., Kafka, RabbitMQ) is essential.
• Familiarity with Kubernetes, Docker, and container-based deployments is expected.
• You should have an understanding of software performance profiling, benchmarking, and optimization.
• A strong grasp of service resilience patterns: timeouts, retries, bulkheads, circuit breakers is required.
• Excellent problem-solving and debugging skills in large-scale systems are necessary.

Benefits:

• We offer a competitive salary.
• A comprehensive healthcare benefit package is provided.
• There are opportunities for career growth within the organization.
