Junior Compute Architect
Level inferred from job title
Job description
An Early Career Processor Architect role in Fractile's Processor Architecture team, focused on learning to define compute engines, ISA definitions and programming models for AI inference silicon. The position offers mentoring from senior architects and exposure to performance modelling, specification writing, bottleneck analysis and pre- and post-silicon validation.
At a glance
- Work mode
- Remote · United Kingdom
What you'll do
- Learn how to define the compute engines, ISA definitions and programming models that sit at the heart of Fractile's silicon
- Work closely with senior architects and the logical design, physical design, and verification teams
- Gain real exposure to performance modelling, specification writing, bottleneck analysis, and pre- and post-silicon validation
- Build toward owning more architectural work with mentoring from experienced architects
What we're looking for
- A degree (BEng, MEng, MSc or equivalent) in Electronic Engineering, Computer Engineering, Computer Science, or a related field — or equivalent practical experience
- A solid foundational understanding of computer/processor architecture, including matrix- and vector-centric floating-point arithmetic and memory hierarchies, gained through study, projects, internships, or research
- Some exposure to RTL design concepts and how physical design constraints feed back into architectural choices — academic or internship-level experience is fine
- A clear communicator, comfortable working across architecture, modelling, implementation, verification, and software teams, who thrives in ambiguity and fast iteration
- Real hands-on exposure to processor or accelerator design, through a final-year project, FPGA build, RISC-V implementation, internship, or research
- Comfort working across disciplines and a track record of thriving in ambiguity and fast iteration
Nice to have
- Hands-on exposure to architectural performance modelling tools (gem5, SystemC, or custom cycle-accurate simulators), compiler/toolchain interactions, or AI acceleration/vector-matrix compute, through study or projects
Your team
Processor Architecture
Sits within Fractile's hardware organisation, which owns everything from compute engine definition and ISA design through memory hierarchies, on-chip interconnects, and the path from early architectural exploration through to tapeout and post-silicon validation. Architecture is built in constant collaboration with logical design, physical design, and verification teams.
Benefits
- Competitive salary reflective of experience and the specialist nature of the role
- Meaningful equity so everyone shares in the value creation
- Private Medical, Dental and Vision
- Contributory Pension
- 25 Days holiday plus bank holidays
- Life/Critical Illness Insurance
- Diverse & fun office

About Fractile
Fractile is seeking to increase the clock speed of global progress, one chip at a time.
Fractile was founded in 2022 on the bet that the world's most capable AI systems would be limited in their impact by the time taken to produce useful outputs. The company builds chips and systems that efficiently generate output at thousands of tokens per second while handling the complexity and capacity challenges of operating large models at very long contexts.
Mission
To radically re-invent the hardware that frontier AI models run on, so that inference speed no longer limits the impact of the world's most capable AI systems.
Key facts
- 2022
- AI hardware / semiconductors
- Founded in 2022
- Building chips and systems for fast AI inference at very long contexts
- Raised $220M from investors including Founders Fund and Accel
- Work involves technologies subject to UK, US and other international export control regulations

What they value
- We believe the hardest problems get solved by the broadest range of minds
- Committed to Equal Employment Opportunity through attracting and retaining a diverse team and building an inclusive environment
