Overview
Manchester We are looking for skilled software engineers to build tools that will shape how performance evaluation and analysis is done on Arm platforms.
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. We also ensure the capabilities we build land in Google's Perfetto by contributing features to its tracer, analyzer, and UI.
Responsibilities
* Build & evolve Telemetry solution so developers can apply performance methodologies on Arm and act on performance signals.
* Contribute to Perfetto to make Arm performance methodologies first-class on Android.
* Work with architects & analysis teams to translate findings and requirements into features, tests, examples and documentation.
* Validate performance methodologies with synthetic workloads and targeted microbenchmarks (occasionally in Arm assembly).
* Partner with kernel and firmware teams to ensure the right performance-measurement primitives (PMUs, perf_event interfaces, etc) exist and are usable.
How we work
Nobody checks every box! We value learning velocity and curiosity about how compute systems really work. We give time to ramp on unfamiliar languages/stacks (C++ in Perfetto, kernel perf system, TS/JS, SQL). 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. Within that framework, we empower groups/teams to determine their own hybrid working patterns, depending on the work and the team's needs. Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.
Technical Requirements
* Strong Python for tooling, data processing, and workflow automation.
* Comfortable in C/C++ to contribute to Perfetto's tracer/analyzer (C++), and read Linux kernel C to reason across kernel performance systems.
* Proficient debugging & problem-solving skills.
* Experience shipping developer-facing tools and iterating with real users.
Desirable Skills
* SQL (e.g., SQLite) for trace querying/analysis.
* Web technologies (TS/JS, HTML, WebSocket/WebUSB) for Perfetto UI integrations.
* Exposure to hardware system architecture (pipelines, caches, MMUs, interconnects, timers, multithreading).
* Open-source contributions and modern CI/CD experience.
* Good understanding of OS primitives (processes, threads, locks, virtual memory) and how they relate to application performance.
* Assembly basics and familiarity with Arm architecture.
* Established experience or a Bachelor's (or above) degree or equivalent experience in a STEM subject.
