About the Role

At Clockwork, we are building next-generation observability and control for modern infrastructure. As an eBPF / Linux Kernel Developer, you will work at the kernel level to build high-performance sensors and control mechanisms that power deep visibility into networking and system behavior. This role is ideal for engineers who enjoy working close to the metal and want their work to directly shape how large-scale systems are observed and understood.

What You’ll Do

• Design and implement kernel-level observability and control using eBPF.
• Build high-performance networking sensors for monitoring TCP/IP behavior and system interactions.
• Work deeply with Linux kernel internals, networking subsystems, and system call paths.
• Develop and optimize low-level C/C++ and eBPF programs for minimal overhead and maximum fidelity.
• Integrate eBPF-based telemetry into Clockwork’s observability pipelines (metrics, traces, and signals).
• Collaborate closely with backend and platform engineers to translate kernel data into actionable insights.

What You Bring

• 7+ years of experience with Linux internals and kernel-level development.
• Deep understanding of the TCP/IP stack, networking flows, and performance characteristics.
• Proficiency in C/C++ for low-level systems programming.
• Hands-on experience with eBPF tooling such as bcc and libbpf.
• Ability to reason about performance, memory safety, and concurrency in kernel-space code.

Bonus Points

• Experience integrating eBPF-based telemetry into large-scale observability systems.
• Familiarity with metrics, tracing, or profiling pipelines.
• Prior work on high-throughput or latency-sensitive infrastructure.
