Staff Software Engineer - AI Compute Libraries & Performance

Build the AI compute libraries that turn next-generation hardware into real performance.

As a Staff Software Engineer, you will design and optimise high-performance compute kernels for AI workloads. You will work across linear algebra, tensor operations, numerical correctness and low-level performance.

Your work will help customers get more from advanced AI hardware. That means shaping the libraries behind faster, more reliable AI systems at scale.

You will write C++ and Python, profile on Linux and make hard trade-offs across memory, threading and numerical behaviour. You will also guide technical direction, review designs and help engineers make better decisions.

This role suits someone who wants deep technical ownership without moving away from hands-on engineering.

You will join the ML Kernels & Runtime team, which builds the compute libraries that expose hardware performance to customers. The work is technical, detailed and close to the machine.

Engineers own problems from design through validation, benchmarking and production quality. Decisions are made through evidence, clear technical reasoning and open debate.

You will move quickly, speak up when something can be better and help others raise the quality of their work. Leadership here means taking responsibility for outcomes, not waiting for permission.

• Excellent C++ and Python skills, with experience building performance-sensitive software
• Strong understanding of processor architectures, Linux profiling and low-level optimisation
• Proven technical leadership, including guiding engineering direction, reviewing designs and mentoring others
• Ability to balance hands-on implementation with broader ownership and team impact
• Experience with numerical correctness, benchmarking, regression testing or validation
• Clear communication, strong judgement and the confidence to challenge ideas constructively

While we have outlined a set of requirements, we value transferable skills and diverse experiences. If you meet most of our essential criteria, we encourage you to submit an application and showcase how your background makes you a strong candidate.

Applicants must have the legal right to work in Poland. Unfortunately, we are unable to provide visa sponsorship or support visa applications for this role.
