Member of Technical Staff, Linux Kernel

Deepen kernel-level diagnosis and remediation. This is the foundational, cross-substrate seat: the platform's fixes are only as good as its kernel reasoning.

Note: this seat opens later. We're listing it now so the right person can introduce themselves early.

A note on location

Remote, with four hours of overlap with Pacific or IST. We don't count hours. We ask for the overlap because this work involves a lot of come look at this dump with me, and that falls apart across a twelve-hour gap.

If you're in Seattle, Toronto or Bengaluru, we'd like to see you in person sometimes. It isn't a condition of the job.

The bar

• 10+ years of relevant engineering experience.
• Deep Linux kernel internals.
• Crash and ramdump forensics, live and post-mortem.
• Kernel tracing and profiling: ftrace, perf, eBPF.
• Driver and BSP experience.
• Strong C.
• Proficient in day-to-day work with CLI-based AI coding tools like Claude Code (or an equivalent). It's how the team operates, not a nice-to-have.

What you'll do

• Build ramdump and crash forensics: drgn, vmcoreinfo, ramdump parsing, post-mortem analysis under customer deadlines.
• Reason across scheduler, memory management, and driver internals.
• Ground remediations in kernel source.

Bonus

• Android kernel.
• ARM64 internals.
• Embedded / hardware bringup.
• drgn and crash tooling.
• Upstream contributions (patches accepted on LKML).
• Yocto distro bring-up.

What we offer you

• A front seat as we scale. Customer calls, the roadmap, the pipeline, how the company is actually doing. What you build carries your name on it, and the scope grows faster than the org chart does.
• Top-of-market salary, and founding equity worth having. You're early enough that the ownership is real, not decorative. We'll walk through the full picture on the first call, and this shouldn't be a guessing game.
• AI, all the way down. We use it for everything: writing code, reviewing it, research, ops, internal tooling. Any tool that unblocks you, we buy. If you already work this way, you'll feel at home in a day.
• Your calls to make, from week one. Architecture, tooling, how the work gets done. These aren't consultations here.
• Support while you make them. The founders are hands-on. You own the decision but you don't make it alone.
• Comprehensive medical insurance for you and your family.
• Start-up perks and flexible time off, the kind people actually take.
• A lean team, senior, and kind in a way that's rare at this pace. People share what they know and help before they're asked. It's the part of this job we're proudest of.

What to expect after you apply

• Screening call with Head of People & Business Operations
• Technical conversation with Co-founder/CEO
• Technical exercise with Co-founder/ Head of Engineering
• Final conversation with Co-founder/CEO
