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.
What You'll Do
* 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).
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
* 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.
*Education & Qualifications:*
Established experience or a Bachelor's (or above) degree or equivalent experience in a STEM subject.
*Accommodations at Arm*
At Arm, we want to build extraordinary teams. If you need an adjustment or an accommodation during the recruitment process, please email. To note, by sending us the requested information, you consent to its use by Arm to arrange for appropriate accommodations. All accommodation or adjustment requests will be treated with confidentiality, and information concerning these requests will only be disclosed as necessary to provide the accommodation. Although this is not an exhaustive list, examples of support include breaks between interviews, having documents read aloud, or office accessibility. Please email us about anything we can do to accommodate you during the recruitment process.
*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. 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.
*Equal Opportunities at Arm*
Arm is an equal opportunity employer, committed to providing an environment of mutual respect where equal opportunities are available to all applicants and colleagues. We are a diverse organization of dedicated and innovative individuals, and don't discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or status as a protected veteran.
