Senior Engineer - Linux

The eBPF APM team is building a zero-instrumentation observability solution that automatically discovers services on every host, supports both plaintext and TLS-encrypted traffic, classifies Layer 7 protocols, decodes service-level traffic, and reports RED (requests, errors, duration) metrics. Leveraging deep expertise in eBPF, the team operates across a wide range of Linux kernel versions, distributions, and complex customer environments. In addition to low-level networking, the team solves challenges related to protocol versioning, TLS detection across diverse languages and runtimes, and resilient performance in production systems​

We’re looking for a senior engineer with strong systems-level thinking and a good understanding of Linux. You should be comfortable working close to the kernel, ideally with experience in eBPF, or with a strong desire to dive into it. Proficiency in C/C++/ Go is essential, and familiarity with networking protocols, TLS internals, or distributed tracing is a strong advantage.

You’ll join a high-impact team tackling ambitious technical challenges—like decoding traffic across multiple protocols, and ensuring high-fidelity metrics in complex, real-world environments. You’ll be expected to lead design and implementation efforts, contribute to roadmap planning, and collaborate across teams to ensure our solution remains robust, scalable, and frictionless for our users.

This role is a great fit for engineers who thrive on low-level, performance-sensitive problems, and want to shape the future of observability through cutting-edge kernel technology.

At Datadog, we place value in our office culture - the relationships that it builds, the creativity it brings to the table, and the collaboration of being together. We operate as a hybrid workplace to ensure our employees can create a work-life harmony that best fits them.

What You’ll Do

Design and build core components of our zero-instrumentation APM product using eBPF and Go

Develop systems to auto-discover services, classify L7 protocols, and extract RED metrics from both plaintext and TLS traffic

Solve complex challenges around protocol parsing, encryption handling, and performance at the kernel level

Ensure broad compatibility across Linux kernel versions, distributions, and diverse customer environments

Collaborate across teams to drive technical direction, improve reliability, and scale the system for production use

Who You Are

You have significant experience in backend or systems-level development, with strong proficiency in Go or similar languages (C/C++)

You’re comfortable working close to the Linux kernel and have experience (or interest) in eBPF, networking, or observability tooling

You care deeply about performance and efficiency

You’ve built or operated scalable systems in complex environments and understand how to design for reliability and compatibility

You thrive in a fast-paced, technically deep environment, and are excited to solve hard problems with a small, focused team

You’re excited about leveraging AI tools to enhance how you code, solve problems, and build – or eager to learn how.

Datadog values people from all walks of life. We understand not everyone will meet all the above qualifications on day one. That's okay. If you’re passionate about technology and want to grow your skills, we encourage you to apply.
