Senior ML Compiler Engineer

The Role

We are looking for Senior ML Compiler Engineers with experience in machine learning compilation to work on the compiler stack for our ground-breaking AI accelerators. You can be based in our Bristol office or London.

Fractile isn't another AI startup gluing together frameworks. We are designing a full-stack execution engine: hardware, compiler, runtime, to build the world's largest language models 100 x faster than today's systems. That ambition forces us to rethink everything from first principles.

For compiler engineers, this is a rare moment: the architecture is still being shaped. The IR, the lowering strategy, the optimisation passes, the execution model - you get to define its future.

In this role, you will:

• Develop the machine learning compiler stack for Fractile’s innovative AI acceleration hardware

• Enable industry-leading performance of the latest LLMs on Fractile’s accelerators

• Work with hardware, driver runtime, and ML engineers in a highly collaborative hardware-software co-design methodology

It would be great if you have

• Proven experience of the development of machine learning compilers using industry standard technologies such as MLIR or TVM

• Up-to-date knowledge of machine learning techniques and technologies

• A good understanding of computer architecture and performance optimisation techniques

• Excellent C/C++ skills and solid experience of industry standard development tools and technologies

• An creative and innovative mindset, and a willingness to take ownership and drive results in a fast-paced environment

• Computer Science, Electronic Engineering, Maths, Physics, or related degree and 4+ years of industry experience

You may also have

• Previous experience in a startup or small team environment

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!
