About Graphcore

At Graphcore were building the future of AI 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 part of the SoftBank Group backed by significant long-term investment we are delivering key technology into the fast-growing SoftBank AI meet the vast and exciting AI opportunity Graphcore is expanding its teams around the are bringing together the brightest minds to solve the toughest problems in a place where everyone has the opportunity to make an impact on the company our products and the future of artificial intelligence.

Job Summary

We decide whether entire racks of machines are good enough to enter production. Our team builds and runs measurements on large-scale Linux clustersfrom a single rack up to datacentre-scale systems. We use these measurements to determine system performance reliability and whether a system can be trusted in production.

You will work across:

• Designing and running measurements on distributed systems
• Analysing performance and reliability results
• Improving systems that execute measurements at scale

Typical work includes:

• Running measurements on large-scale Linux clusters (rack-level and beyond)
• Using and extending tools such as pytest for measurement execution
• Measuring compute network and ML workload performance
• Analysing variability and repeatability of results

Engineers in this team are not limited to a single area. You may work on infrastructure workloads or analysis depending on the problem. You are free to specialise but the team is responsible for ensuring complete coverage. This role is not purely infrastructure or data analysis. It combines systems engineering measurement and interpretation.

We are looking for engineers who:

• Are comfortable working with distributed systems at scale
• Can reason about performance and reliability
• Prefer clear evidence-based conclusions over assumptions

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 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 on accuracy and usefulness to decision-making
• Comfortable working in areas where requirements are not fully defined and judgement is

Desirable

• Experience working withlarge-scale or distributed systems(e.g. clusters cloud
• platforms 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 (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; 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.
