- Strong C and/or Rust, and excellent engineering judgement around safety, testing, debugging, and failure modes
- A reliability-first mindset: you design for observability, diagnosability, and recovery paths that are predictable and testable
- Comfortable working close to the hardware/software boundary (bootloaders/BSP/kernel-adjacent work) and collaborating tightly with HW, driver, and runtime teams
- Collaborative and high-ownership. You communicate clearly, move fast, and enjoy working through hard problems with others
- Computer Science, Electronic Engineering, Maths, Physics, or related degree and 3+ years of industry experience
Nice to have
- Embedded platform / systems firmware experience (board management, BMC-style stacks, rack controllers)
- OpenBMC experience and/or embedded Linux image build/customisation experience
- Zephyr (or similar RTOS) experience
- Security-minded, with practical instincts around secure boot, signed updates, device identity, and designing systems that fail safe and recover cleanly (direct experience in some areas is a plus)
- Kernel device work (drivers, device tree, bring-up, perf/trace)
- Hardware bring-up experience, including lab tools (logic analysers, oscilloscopes, waveform viewers)
- RISC-V familiarity
- Experience with GPUs or ML accelerators
If you want to build the control software that keeps rack-scale systems stable, safe, and secure for next-gen AI, come build it together.

At Fractile, we’re building what we believe will be the world’s fastest AI inference chip from the ground up. We’re balanced across hardware and software engineering, and HW/SW co-design is real here. We move fast, and we help each other move fast. We care about each other, the software we ship, and the people who rely on it.
To validate behaviour, our functional simulator allows us to iterate at scale with real software before the hardware exists. It runs across multiple machines, supports large experiments, and helps verify the correctness of our low level firmware, runtime stack and compiler lowering.
You’ll be there for the first end-to-end runs against realistic device behaviour, the debugging sessions that unblock whole teams, and the moments where simulator fidelity turns into better software, better silicon decisions, and faster bring-up.
What you’ll do
- Build a functional simulator of Fractile’s AI accelerator hardware including a custom ISA
- Implement the device models and behaviours that matter for software correctness: MMIO, interrupts, DMA, memory behaviour, concurrency, and error paths
- Work closely with runtime, kernel, firmware and HW engineers to shape simulator interfaces
- Make it usable at scale: tracing, determinism/reproducibility, CI integration, and containerised workflows
- Collaborate daily with hardware, software, and ML engineers to validate assumptions and close gaps early
What we’re looking for
- Strong C and comfort working in large low-level codebases
- Good intuition and knowledge of low-level hardware behaviour: registers/MMIO, interrupts, memory ordering, concurrency, and failure modes
- You enjoy hard system-level problems, and you take them end-to-end until the results are measurable
- Computer Science, Electronic Engineering, Maths, Physics, or related degree and 3+ years of industry experience
Nice to have
- You’ve built or extended hardware simulators or emulators.
- SystemC experience
- QEMU device model experience is ideal, even better in the TCG
- Docker and orchestration tooling (Kubernetes)
- Familiarity with RISC-V and x86 architectures
- Python experience useful
If you want to build the simulator that makes rack-scale software real before rack-scale hardware exists, come build it together.

Apply to FractileAt Fractile, we believe that we are building the worlds fastest and most energy efficient AI inference chip from the ground up. Half the company is dedicated to hardware design and the other half to software. Our team works hand in hand with the hardware engineers to extract every last drop of performance from the architecture, and we are building a world class interdisciplinary team to make that happen.
About the role:
We are creating a new team of Rust engineers to work on greenfield software with members having scope to influence architecture, direction and engineering practices from day one.
In this role, you will:
- Write Rust server side software to build a reference implementation of a full AI inference stack specifically tuned to take advantage of the hardware we are building, including a Linux kernel driver in Rust. The hardware will be housed in data centres so the remit of work includes building out all the required cloud based tooling as well.
- You will be expected to conduct your own research into the state of the art in AI inference and implement these ideas. You will be encouraged to take initiative and make sense of difficult problems in unfamiliar areas.
What we are looking for:
- We are looking for creative problem solvers and generalists who have the grit to tackle hard problems.
- Experience in serving AI workloads (for example vLLM, SGLang or Rust equivalents) or strong systems level engineering experience. If you don’t have AI experience then experience in a wide range of complimentary industries would also be beneficial. Specifically experience moving large amounts of data around in real time at low latency, paging, caching etc.
- We will consider candidates without commercial Rust experience as long as they are strong senior developers in another systems language (e.g. C/C++ etc.) and can demonstrate proficiency in Rust through open source contributions and/or personal projects.
If you have a portfolio of Rust projects that you have authored and can share then this will help in the selection process.
We will not subject you to online algorithmic-style testing but any interview will be very technical and you will be expected to have a background in computer science and a deep understanding of Rust. In particular, your ability to read unfamiliar code, understand it and point out problem areas is important to us.
Languages:
- Rust, C, C++ and Python
About us:
- Founded in 2022, team of 70+ which is expanding rapidly
- Modern, open offices in London and Bristol
- Collaborative, problem-solving culture built on deep curiosity, entrepreneurial initiative and technical fluency
