We are seeking a Software Engineer with strong C++ expertise on Linux to join our team. The ideal candidate demonstrates exceptional analytical and logical thinking, the ability to independently infer system behavior from complex data flows, and a deep understanding of performance-critical software.

You will work on designing and optimizing scalable, high-throughput systems, navigating complex architectures, and reasoning about real-world network behavior. Familiarity with telecom environments, protocols, and large-scale traffic systems is highly valued, along with a mindset that proactively identifies problems, deduces root causes, and drives solutions end-to-end.

The eBPF APM team builds Datadogs zero-instrumentation observability platform, enabling automatic service discovery, Layer 7 protocol classification, traffic decoding, and high-fidelity RED (requests, errors, duration) metrics from both plaintext and TLS-encrypted traffic-without requiring customer code changes.

This work spans kernel-space eBPF, user-space Go services, and large-scale distributed systems, operating reliably across diverse Linux kernels, distributions, runtimes, and real-world production environments. The team tackles challenges in protocol evolution, TLS detection across languages and frameworks, and performance-critical data collection at scale.

We are looking for a Staff Engineer who will act as a technical owner and multiplier-driving architecture, influencing the roadmap, and ensuring our APM platform remains robust, scalable, and easy to adopt us and our customers grow.

What Youll Do:
Own major technical areas of the zero-instrumentation APM system, from design through long-term evolution and operational maturity.
Define and drive architecture for kernel-level traffic capture, L7 protocol decoding, and metric extraction using eBPF and Go.
Lead high-impact initiatives addressing protocol parsing, TLS visibility, kernel compatibility, and performance at scale.
Set technical direction and standards for reliability, performance, and maintainability across the team.
Partner cross-functionally with Agent, Tracing, Security, Runtime, and Product teams to align on system design and roadmap priorities.
