Senior Linux Kernel Driver Engineer

Design, develop, and maintain the Linux kernel driver for Fractile’s AI accelerator

Build the performance-critical kernel-space paths that keep the host stack moving: PCIe device management, DMA, memory handling, interrupt handling, and robust recovery paths

Define and evolve the userspace interface the runtime depends on, with a focus on stability, debuggability, and performance

Work in a tight co-design loop with hardware, firmware, runtime and ML engineers: validate assumptions, iterate on behaviour, and close gaps early

Improve tooling/workflows so we move fast without breaking things

You’ve shipped and maintained Linux kernel device drivers in production. Experience with PCIe-attached devices and custom hardware interfaces is ideal.

Strong systems and performance instincts. You can reason about computer architecture, concurrency, and where the time goes

Excellent C and/or Rust, and a pragmatic approach to building high-quality, maintainable & secure kernel code

You enjoy hard kernel and system-level problems, and you take them end-to-end until the measurements move

Computer Science, Electronic Engineering, Maths, Physics, or related degree and 3+ years of industry experience

GPUs / ML accelerators / high‑throughput I/O (NICs, RDMA, storage)

Hardware bring‑up or pre‑silicon simulation experience

Performance work: profiling, tracing, benchmarking, regression tracking

If you want to build the software where every driver win unlocks huge system performance, come build it together.
