## About the Role

* Excellent programming and scripting skills using C++ and Python

 * Understanding of processor architectures and profiling on Linux

 * Possess excellent written and oral communication skills, good work ethics, high sense of team-work
 * Love to produce quality work and be a team player

Desirable

 * Strong command of algorithmic performance - vectorisation, memory hierarchy, threading, lock-free patterns

 * Hands-on with at least one BLAS/DNN stack and able to read/extend kernels

 * Comfort with CPU micro-optimisations and numerical stability/trade-offs across FP32/FP16/BF16/FP8

 * Experience integrating native code into PyTorch or similar (custom ops, extensions, dispatch keys)
 * ABI/API stability and packaging for Linux system (manylinux, wheels)

## Description

As a Senior Software Engineer, you'll build high-performance AI compute libraries for next-generation AI hardware, working on linear algebra, tensor operations, numerical correctness, and low-level performance optimisation.

The Team

This is an exciting opportunity to join an expanding team at Graphcore. Our ML Kernels & Runtime team are responsible for delivering high performance compute library to help customers gain the maximum performance from AI hardware.

Responsibilities and Duties

 * Design and implement kernels for linear algebra and tensor ops (GEMM, batched GEMM, convolutions, reductions, elementwise and fused operations) in C++

 * Own performance and correctness - add microbenchmarks, regression tests, numerics validation

 * Profile and optimise across for next generation of AI hardware - threading, cache locality, memory layout, and kernel launch efficiency.

 * Debug issues, resolve bugs and generally improve the quality and functionality of the product

 * Actively engage in and support Agile ways of working within the team
 * Mentor colleagues within the team, sharing knowledge and providing guidance where appropriate
