Responsibilities
Design and implement high-performance kernels for linear algebra and tensor operations in C++. Profile and optimize code for next-generation AI hardware, focusing on cache locality and memory layout.
Requirements
Requires excellent C++ and Python skills with a deep understanding of processor architectures and Linux profiling. Experience with BLAS/DNN stacks and integrating native code into PyTorch is highly desirable.
Full job description
About the job
Build the compute kernels that make next-generation AI hardware perform at its limit.
As a Senior Software Engineer, you will create high-performance AI compute libraries for Graphcore’s next-generation hardware. Your work will sit close to the hardware, where every design choice matters.
You will own kernels for linear algebra and tensor operations, including GEMM, convolutions, reductions and fused operations. You will improve performance, correctness and numerical reliability across critical AI workloads.
This role is for engineers who enjoy hard performance problems and care deeply about quality. You will help shape software that enables customers to get more from AI hardware.
The team and culture
You will join the ML Kernels and Runtime team, an expanding group focused on high-performance compute libraries. The team works close to the hardware and close to the product.
Work happens through clear ownership, practical decision-making and fast technical feedback. Engineers profile, test, debug and improve the product with accountability for real outcomes.
You will be expected to speak up, share knowledge and help others raise the bar. Mentoring, technical judgement and all-round leadership matter here
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
Candidate Profile
Essential
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
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)
Benefits
· Unlimited annual leave · Up to 5% matched pension · Phantom equity – share in Graphcore’s success · True flexibility in how and where you work · Office spaces designed for collaboration · Free food and an on-site barista · Health cash plan · Income protection · Life assurance · Along with other benefits you can choose from (private medical insurance, dental plan etc)
We welcome people from all backgrounds and experiences and are committed to building an inclusive environment where everyone can do their best work.
We’re an equal opportunity employer and recognise that everyone brings different strengths and perspectives. If you need any adjustments during the interview process, just let us know - we’re happy to support you.
