Staff Performance Tools Engineer

Join Arm's Telemetry team to build open-source tools that shape how performance evaluation is done on Arm platforms. You will own features end-to-end, collaborating with architects and analysis teams to translate methodologies into usable tooling and documentation. You’ll validate methodologies with synthetic workloads and microbenchmarks, and partner with kernel/firmware teams to ensure practical performance-measurement primitives exist. This role offers learning, collaboration, and the chance to contribute to open-source communities and Arm's evolving architecture features.
