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 orsystems over several years
• Experience working inLinux-based environments ideally with distributed or high-performance systems
• Proficiency inPython
• Experience withautomation 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 tointerpret results and communicate findings clearly with an emphasis onaccuracy and usefulness to decision-making
• Comfortable working in areas where requirements are not fully defined and judgement isrequired

Desirable

• Experience working withlarge-scale or distributed systems(e.g. clusters cloudplatforms HPC environments)
• Experience with performance reliability or systems-level testing/measurement
• Familiarity withpytest or similar frameworksfor structured test/measurement execution
• Experience analysingsystem behaviour under load(compute network or ML workloads)
• Experience working with containerisation orchestration or provisioning systems ( 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; were 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.
