Fractile is building a new class of AI accelerator — designed to run the world's largest language models dramatically faster than existing systems. Founded in 2022 and scaling fast, we work at the intersection of cutting‑edge hardware and software, in modern offices in London and Bristol.

Location: London or Bristol
Employment type: Full-time
Work arrangement: Hybrid (3 days onsite, 2 days remote)

The Role

To build hardware that doesn’t yet exist, you first have to model it — with precision, depth, and an eye for the trade‑offs that matter. At Fractile, high‑fidelity pre‑silicon models shape our architecture, performance, and product design long before hardware exists. This is where you come in.

You will develop the pre‑silicon models of Fractile’s AI acceleration hardware, enabling:

• Architectural exploration and definition
• Functional modelling
• Performance modelling and bottleneck analysis
• Early...
