Job Summary

We turn measurements from large-scale systems into engineering decisions. Our team runs workloads on Linux clusters (from rack scale upwards) and collects detailed performance and reliability data. The key challenge is interpreting these results correctly and deciding whether a system is ready for production.

You will work on:

Analysing results from measurements of distributed systems
Understanding performance variability and repeatability
Defining what “normal” and “acceptable” system behaviour looks like

Typical work includes:

Working with measurement data from compute, network, and ML workloads
Analysing results produced by automated test frameworks (e.g. pytest-based systems)
Comparing results across runs, configurations, and system scales
Helping define thresholds for pass/fail decisions

You may also:

Influence how measurements are designed to produce better data
Improve how results are stored, queried, and interpreted

This is not a traditional data analysis or BI role. The focus is on understanding system behaviour and supporting engineering decisions.

We are looking for engineers who:

Are comfortable working with real-world, imperfect data
Can reason about distributed systems performance
Focus on evidence and correctness rather than presentation

Selection criteria:

Our engineers typically bring significant practical experience and sound engineering judgement. Depth in one area is valued, but the ability to work across boundaries is equally important.

Essential

Strong software engineering experience, typically gained across multiple projects or systems over several years
Experience working in Linux-based environments, ideally with distributed or high-performance systems
Proficiency in Python
Experience with automation and CI/CD systems (e.g. GitLab CI, Jenkins, GitHub Actions)
Ability to design, implement, and run experiments or tests that produce meaningful results
Ability to interpret results and communicate findings clearly, with an emphasis on accuracy and usefulness to decision-making
Comfortable working in areas where requirements are not fully defined and judgement is required

Desirable

Experience working with large-scale or distributed systems (e.g. clusters, cloud platforms, HPC environments)
Experience with performance, reliability, or systems-level testing/measurement
Familiarity with pytest or similar frameworks for structured test/measurement execution
Experience analysing system behaviour under load(compute, network, or ML workloads)
Experience working with containerisation, orchestration, or provisioning systems (e.g. Docker, Kubernetes, OpenStack)
Proficiency in other applications programming languages (e.g. C++)
Exposure to data analysis, statistics, or interpreting variability in results

Benefits

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

Sponsorship

Applicants for this position must hold the right to work in the Poland. Unfortunately at this time, we are unable to provide visa sponsorship or support for visa applications.
