Description
Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale.
As Processor Architect, you'll define and drive the architecture of our core compute engines, ISA definitions and programming models through to memory hierarchies, and on-chip interconnects. This isn't just about hitting PPA targets on a spreadsheet; you'll work closely with logical design, physical design, and verification teams to translate architectural intent into working silicon that performs in the real world. Expect to be hands-on in performance modelling, detailed specification writing, bottleneck analysis, pre and post-silicon validation. You'll be the driving force behind the computational heart of our products ensuring every cycle counts and every watt is well spent.

Key Responsibilities
- Define and own the compute engine architecture specifications, balancing performance, flexibility, power, area, and design complexity.
- Proven experience as a Processor Architect, CPU/GPU Architect, or similar role in semiconductor or high-performance computing domains.
- Deep understanding of compute engine and processor architecture and design, including matrix and vector centric floating-point arithmetic and memory hierarchies.
- Background in AI acceleration, vector/matrix compute, or domain-specific processor design.
- Experience with architectural performance modelling tools and frameworks (gem5, SystemC, custom cycle-accurate simulators).
- Familiarity with compiler and toolchain interactions, understanding how software maps to hardware.
- Prior start-up or scale-up experience, someone who thrives in ambiguity and fast iteration.
- Ownership and execution: you will have full agency to drive your work forward
- Founded in 2022, a team of 80+, which is expanding rapidly
- Modern, open offices in London and Bristol
- Collaborative, problem-solving culture built on deep curiosity, entrepreneurial initiative and technical fluency
