AboutGraphcore

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 measures and evaluates large-scale Linux systemsfrom a single rack to data-centre scale. We dont just run benchmarks; we determine whether a system behaves correctly and whether it is reliable enough to be trusted.

The work spans designing workloads building execution systems and interpreting results. A measurement is only useful if it leads to a decision.

You wont be confined to a narrow role. Some engineers here focus on infrastructure others on workloads or analysisbut everyone contributes to understanding system behaviour at scale. You are free to specialise but as a team we are responsible for leaving no gaps.

You might find yourself:

• Expanding measurement coverage from small clusters to full racks
• Designing workloads that expose system behaviour
• Building systems to run experiments across large clusters
• Interpreting results and defining what good enough looks like

This is not a pure infrastructure or data role. The work combines systems engineering measurement and judgement.

Were looking for engineers who are comfortable working where the right answer isnt obvious and where careful measurement matters more than output volume.

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 Graphcore offers flexible working a generous annual leave policy private medical insurance and health cash plan a dental plan pension (matched up to 5%) life assurance and income protection.
