.Net APM Engineer

Roles & Responsibilities :

• .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+). Test and validate behavior across different environments.

• Performance & Overhead Analysis:

• 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.

Mandatory Skills:

• 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

Good to Have Skills

• 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.
