Job Summary

We are looking for a Graduate Software Engineer to join a team pioneering the development of high-performance machine learning (ML) kernels for a new generation of AI hardware. In this role, you will contribute to building optimised compute kernels that support a wide range of ML operators—powering applications from convolutional neural networks (CNNs) to large language models (LLMs). You'll leverage low-level programming and hardware-aware optimisation techniques to extract maximum performance and efficiency from modern accelerators. This is a unique opportunity to work at the intersection of ML, numerical computing, and scalable systems.

The Team

This is an exciting opportunity to join an expanding team at Graphcore. The Kernel Engineering team is responsible for delivering high performance compute library to help customers gain the maximum performance from AI hardware.

Responsibilities and Duties

  • Supporting the design and implementation of kernels for linear algebra and tensor ops (GEMM, batched GEMM, convolutions, reductions, elementwise and fused operations) in C++.
  • Profile and optimise for the next generation of AI hardware - threading, cache locality, memory layout, and kernel launch efficiency.
  • Support performance and correctness - add microbenchmarks, regression tests, numerics validation.
  • Debug issues, resolve bugs and generally improve the quality and functionality of the product.

About you

You are open-minded and collaborative with interests in performance optimisation and memory-efficient designs, and you are looking to join a team of experts. You are comfortable to discuss technical tradeoffs, receive feedback and iterate on solutions and you are drawn to technically challenging problems and use analytical reasoning to navigate unfamiliar domains.

Essential:

  • Bachelor or Master's Degree in Computer Science, Maths, Machine Learning, Data Science, or related field.
  • Experience in C/C++11.
  • Familiarity with Python or scripting tools for automation and testing.
  • Understanding of linear algebra, numerical methods, or scientific computing.
  • Good problem-solving skills and ability to work collaboratively in a fast-paced environment.

Preferred Qualifications:

  • Courseworks or past experience in using ML frameworks, parallel programming, or code optimisation.
  • Exposure to math libraries such as MKL or OpenBLAS.
  • Knowledge of performance analysis tools.

Benefits

In addition to a competitive salary, Graphcore offers flexible working, a generous annual leave policy, private medical insurance and health cash plan, a dental plan, pension (matched up to 5%), life assurance and income protection. We have a generous parental leave policy and an employee assistance programme (which includes health, mental wellbeing, and bereavement support). We offer a range of healthy food and snacks at our central Bristol office and have our own barista bar! We welcome people of different backgrounds and experiences; we’re committed to building an inclusive work environment that makes Graphcore a great home for everyone. We offer an equal opportunity process and understand that there are visible and invisible differences in all of us. We can provide a flexible approach to interview and encourage you to chat to us if you require any reasonable adjustments.
