Charger logistics Inc. is a world-class asset-based carrier with locations across North America. With over 20 years of experience providing the best logistics solutions, they have transformed into a world-class transport provider and continue to grow.

We are seeking a skilled and performance-minded system 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 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.

Responsibilities:

  • Design, develop, and optimize high-performance backend microservices using .NET Core/C#.
  • 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.

  • 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.
  • Excellent problem-solving and debugging skills in large-scale systems.
Preferred Qualifications
  • Experience working with Istio, Consul, or another service mesh.
  • Familiarity with Event Sourcing, CQRS, and DDD patterns.
  • Exposure to Infrastructure as Code tools (Terraform, Helm).
  • Experience with other databases like Redis, MongoDB, or TimescaleDB.
