Staff Software Development Engineer – Linux Endpoint

This is a Linux specialist role, so the depth requirements are real:

• Deep Linux kernel internals - scheduling, memory management, the networking stack, syscalls, the LSM framework - backed by production systems programming in C, Rust, or both.
• Hands-on eBPF for security enforcement, with real comfort at the verifier level. You can write programs that pass BPF_PROG_LOAD across kernel versions and reason about the stack limit, bounded loops, and helper-behavior differences. We write our BPF in Rust (aya / aya-ebpf, no_std). Any eBPF stack transfers - libbpf, BCC, Cilium eBPF, aya - but verifier fluency is non-negotiable.
• BTF and CO-RE, plus the practical realities of portability: task_struct layout drift, LSM config availability, tracepoint ABI.
• Container runtime internals - namespaces, cgroups, seccomp - and how they intersect with kernel-level security tooling.
• Kernel debugging and performance tooling: perf, ftrace, bpftrace, gdb/kgdb, crash-dump analysis.
• 8+ years in systems-level software engineering, with real depth in Linux kernel development and eBPF.
• Demonstrated AI-first development. We build this platform through agentic tooling. AI-driven design exploration, code generation, adversarial plan review, and automated pre-merge quality gates are how work ships here, not a side experiment. You use Claude Code or a comparable tool as a core part of your daily workflow, and you can speak concretely to how it raises both your velocity and your rigor. That matters most in correctness- and security-critical kernel code, where you have to know exactly when to stop and verify by hand.
• A working grasp of systems design patterns and their tradeoffs at the kernel/userspace boundary.
• Full-lifecycle experience, including product release, in an agile environment.
• A track record of technical leadership on complex, ambiguous initiatives that span teams.

• You share successes and failures openly, and you work well with people. You adapt when the situation and the requirements shift. You fix issues before anyone assigns them to you, and you stay persistent through roadblocks, pulling in others when you need to.
• You hold a high bar and push your teams to ship reliable systems, especially where a kernel bug carries outsized risk. You know systems software best practices, from rigorous testing to sharp peer review to architecture that survives contact with production.
• You reach for AI tools to move faster and think more clearly, and you keep the judgment to slow down and verify by hand when the code demands it. You weigh speed against risk and decide from data.
• You feel the weight of enforcement code. You'd rather ship a correct block a day late than a wrong one now, and you choose your failure modes - fail-open or fail-closed - on purpose instead of by accident.
