About Fractile

Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the time taken to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to efficiently generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts.

The workloads that push to the limits of the current frontier are already transformational; it is the technical and economic limits on inference speed that are constraining progress. The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems.

We’re looking for a detail-oriented Lab Technician to keep our Bristol labs running safely and reliably. You’ll support hardware engineers with testing, setup and equipment upkeep in a fast-paced AI hardware company.

Key responsibilities

• Run routine tests and measurements across both Bristol labs, following established procedures

• Set up, maintain, calibrate and troubleshoot lab equipment

• Carry out basic soldering and small rework tasks as needed

• Record results accurately and keep clear, traceable logs

• Uphold health and safety procedures, including housekeeping, equipment safety checks and proactively reporting risks

• Support audits, risk assessments and safe working practices, including for lone working

• Help improve lab processes and SOPs

• Keep both labs organised and stocked, and hand over clearly on the days you’re not in

Requirements

• Experience in an electronics, hardware or lab environment

• Strong attention to detail and a methodical approach to documentation

• Solid understanding of workplace health and safety, with a proactive approach to it

• Able to work independently and as part of a team across two labs

• Right to work in the UK

Desirable

• Experience in or around data centres

• Basic soldering and rework skills (IPC or similar training is a plus)

• Knowledge of liquid cooling systems

• A health and safety qualification (e.g. IOSH or NEBOSH)

What We Offer

• Competitive salary: A competitive salary reflective of your experience and the specialist nature of the role.

• Equity & Ownership: meaningful equity so everyone shares in the value creation

• Benefits: Private Medical, Dental and Vision, Contributory Pension, 25 Days holiday plus bank holidays and Life/Critical Illness Insurance.

• Diverse & fun office: we believe the hardest problems get solved by the broadest range of minds. We are committed to Equal Employment Opportunity through attracting and retaining a diverse team and building an inclusive environment.

Fractile is seeking to increase the clock speed of global progress, one chip at a time. We’ve recently raised $220M from investors including Founders Fund and Accel and our most important work lies ahead. Join us!
