We are looking for an outstanding software engineer with strong CI and automation expertise to build the validation infrastructure behind Arm’s performance methodologies and telemetry tools. You’ll help make performance evaluation on Arm platforms repeatable, scalable, and trustworthy on current and next-generation Arm systems.

About The Team

We build Arm’s Telemetry solution—a set of open‑source reference tools that demonstrate Arm’s performance methodologies across compute subsystems (CPU, interconnects, memory systems, and more). We collaborate with architects across Arm IP groups to turn their methodologies into practical tooling. Our work enables Arm’s internal performance teams, partners, and the wider open‑source community.

What you’ll do

• Build and evolve CI infrastructure that validates performance methodologies across cloud, on-prem, and hardware targets.
• Design controlled, reproducible test environments that help distinguish real regressions from environmental noise when running and profiling targeted workloads.
• Help build synthetic workloads and targeted microbenchmarks (occasionally in Arm assembly) that help in our validation efforts.
• Work with architects & analysis teams to understand performance methodologies and embed this knowledge into validation strategies.
• Partner with IP and silicon teams to ensure that tools and methodologies work well on the next generation of Arm products.
• Ensure that our testing scales with the ever growing demand for new methodologies, tools, IP and physical designs.

How we work

Nobody checks every box. We value learning velocity and curiosity about how compute systems really work. We give engineers time to build the Arm-specific hardware and performance-analysis context needed for the role.

Engineers typically own larger features end-to-end, which gives space to build deep expertise in the domain. You won't be alone in the process: We’re collaborative, and incrementally do code design and review as a team.

Core Skills:

• Experience building reliable automated test systems where reproducibility matter.
• Understanding of performance measurement in CI environments, including the challenges of noise, and regression detection.
• Proactive and relentless about improving CI reliability, validation coverage and developer feedback loops.
• Strong Python for workflow automation, tooling and data processing
• Proficient in debugging & great at problem solving.

Desirable Skills:

• Knowledgeable in C/C++/AArch64 assembly.
• Some understanding of hardware system architecture (pipelines, caches, MMUs, interconnects, timers, multithreading).
• Experience with hardware-in-the-loop testing, benchmark automation, or performance dashboards.
• Familiarity with Linux performance tooling (perf, ftrace, ...) or telemetry systems.

Please note that no relocation package is available for this role.

If visa sponsorship is required, Arm will meet all costs associated with sponsorship for the employee only. All fees associated with any spouse/dependants, will be the responsibility of the successful candidate.

Hybrid Working at Arm

Arm’s approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We believe in bringing people together face to face to enable us to work at pace, whilst recognizing the value of flexibility.
