Dotnet APM Engineer

• .NET Instrumentation:

• Implement and maintain application instrumentation using OpenTelemetry SDK for distributed tracing, metrics, and logs across .NET applications (Core and Framework). * Auto-Instrumentation:

• Evaluate, integrate, and enhance auto-instrumentation capabilities using OpenTelemetry .NET auto-instrumentation libraries. Build custom instrumentation where necessary. * SDK & Framework Compatibility:

• Ensure compatibility across various .NET runtimes and versions (.NET Core, .NET Framework, .NET 5/6/7/8+)

• Tune instrumentation code to minimize performance overhead. Contribute to best practices for high-efficiency observability implementations. * Tooling & Integration:

• Integrate instrumentation with backend systems such as Jaeger, Prometheus, Grafana, OTLP collectors, and internal observability platforms.
• Documentation & Developer Enablement:
• Create clear documentation, sample apps, and templates to help internal teams adopt observability standards and SDKs with ease. * Collaboration:

• Work with cross-functional teams including application developers, DevOps, and platform engineers to understand instrumentation needs and guide adoption.

• Minimum 3+ years software development experience with a focus on .NET/.NET Core (C#).
• Deep understanding of .NET application internals, runtime behavior, diagnostics APIs, and async programming patterns.
• Hands-on experience with OpenTelemetry SDK and concepts like spans, traces, metrics, and logs.
• Experience with auto-instrumentation and diagnostics source/event listener patterns in .NET.
• Familiarity with telemetry backends: Jaeger, Zipkin, OTEL Collector, Prometheus, or cloud-native observability stacks.
• Strong understanding of application performance, observability concepts (golden signals), and modern microservices patterns.
• Experience with CI/CD pipelines and containerized environments (Docker, Kubernetes) is a plus

• Contributions to OpenTelemetry or other open-source instrumentation projects.
• Experience developing reusable .NET libraries or SDKs.
• Familiarity with other programming languages (Java, Python, Node.js) and crosslanguage trace correlation.
• Exposure to distributed systems, message queues, databases, and cloud services
