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.

We are looking for a talented detection engineer, someone who looks at the world differently, who explores, hunts, lives to beat the system and challenge it. Someone who can address tough security problems and deliver solutions quickly.
What will you do?
You will be responsible for detecting the newest malware and exploits based on SentinelOnes EPP platform. The role includes an end to end responsibility for behaviour based detection capabilities, starting from reversing the samples, designing new methods to detect or prevent those, and implementing it in the product in the end. You will be developing and using internal research tools, PoCs and discovering new ways to detect/prevent exploitation attacks (EoP, drive-by attacks and more).
