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
Requirements: 5+ years of systems or backend engineering experience, with strong Go skills
Solid grounding in operating system internals or low-level programming (C/C++/Rust, kernel, syscalls, memory management)
Deep understanding of Linux networking, syscalls, and process/container isolation
Familiarity with cloud-native environments (Kubernetes, containers, CRI/CNI)
A performance mindset- you think about cache lines, allocations, and tail latency
Care about clean, maintainable, well-architected code
Love working on developer-first products and want your work to have real impact
Bonus Points:
Hands-on experience with eBPF or other kernel instrumentation frameworks
Background in protocol parsing, packet processing, or network observability
Contributions to open-source systems or infrastructure projects
This position is open to all candidates.
