Essential:

• Strong software engineering experience across multiple projects or systems
• 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, emphasizing 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

• Analyse results from measurements of distributed systems
• Understand performance variability and repeatability
• Define what “normal” and “acceptable” system behaviour looks like
• Work with measurement data from compute, network, and ML workloads
• Analyse results produced by automated test frameworks (e.g. pytest-based systems)
• Compare results across runs, configurations, and system scales
• Help define thresholds for pass/fail decisions
• Influence how measurements are designed to produce better data
• Improve how results are stored, queried, and interpreted
