Job description

Salary Range: PLN 260,400 - 352,200

We're building the future of AI compute. We're a team of semiconductor, software and AI experts, with deep experience in creating the complete AI compute stack—from silicon and software to infrastructure at datacenter scale. As part of the SoftBank Group, backed by significant long‑term investment, we are delivering key technology into the fast‑growing SoftBank AI ecosystem. To meet the vast and exciting AI opportunity, Graphcore is expanding its teams worldwide. We are bringing together the brightest minds to solve the toughest problems, in a place where everyone can make an impact on the company, our products, and the future of artificial intelligence.

Job Summary

As a Senior Software Engineer, you will develop new kernels and support existing kernels for linear algebra operations on a new generation of AI hardware.

The Team

This is an exciting opportunity to join an expanding team. Kernel Engineering team is responsible for delivering a high‑performance compute library that helps 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 the 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
• Excellent written and oral communication skills, good work ethics, high sense of teamwork
• 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 systems (manylinux, wheels)

Benefits

In addition to a competitive salary, Graphcore offers an annual leave policy, medical and dental health plans, a gym card, and an employee pension matched up to 4%. We review our benefits yearly to ensure we offer a valuable and rewarding benefits programme. 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.
