Job description

At 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
• Fractile offers hybrid working. You will be able to work in either our London or Bristol office three days per week and for from home for the remaining two days.

Export control and security clearance:

Certain roles may involve working on technologies subject to export restrictions. Applicants may be required to undergo additional eligibility checks to ensure compliance with applicable law.
