What you'll do
In this role, youll write low-level code that hooks deep into runtimes and OS internals (via eBPF) to capture runtime data with near-zero overhead. Basically, youre creating the eyes and ears inside applications, so we can detect intrusions as they happen.
Youll be pushing the envelope of what eBPF and kernel tech can do: tracing syscalls, monitoring network flows, and intercepting anything attackers might exploit. Your work will help determine exploitability and flag compromises instantly - even for zero-day attacks that nobody has seen before.
This is a high-impact, experimental role: part engineer, part hacker - optimizing for performance and reliability while youre bending the rules of the OS. If you love digging into assembly, performance tuning, and building tools that peer into the guts of running software, come join us. Youll have the freedom to innovate at the lowest levels of the stack (and we promise, no boring corporate kernel modules here - only the fun stuff!).

Were looking for a Low-Level Developer to join the team - someone who loves working close to the kernel, cares deeply about performance, and wants their code measured in nanoseconds and bytes.
What You'll Do:
Design and build the in-cluster sensor that powers groundcover's observability platform
Write low-overhead, high-performance instrumentation using eBPF and Go
Tackle hard problems in Linux internals, networking, and protocol parsing
Push the boundaries of what can be observed without modifying customer code
Ensure the sensor runs reliably across a huge variety of kernels, distros, and Kubernetes setups
Collaborate with backend, infrastructure, and product teams to ship features end to end

At our company, what you do matters. Every day, we protect over 100,000 organizations worldwide from increasingly sophisticated cyber and AI-driven threats, securing their AI transformation.
Our prevention-first approach safeguards hybrid networks, cloud environments, digital workspaces, and AI systems, stopping attacks before they happen.
This is where innovation meets real-world impact. Youll help customers across industries operate with confidence in a rapidly changing digital world, working alongside smart, curious people who take ownership, challenge assumptions, and solve complex problems.
Were proud to be recognized by TIME, Newsweek, and Forbes for excellence and workplace culture.
What really sets our company apart is the opportunity to grow, contribute, and help companies navigate their AI transformation securely.
If youre excited to work at the forefront of AI-driven security on a global scale, this is the place to do it.
