Job Overview
Would you like to join the team that defines the micro‑architecture of the future Arm CPUs, and influence the future by crafting products that millions of people will use all over the world? We are looking for engineers willing to accept the challenge of working with us on defining next‑generation products optimised for cutting‑edge AI algorithms that target markets from IoT devices to mobiles, laptops and servers.
The performance team within the CPU group is responsible for early performance exploration and analysis that drive the definition of the next generation Arm CPUs. By joining the team, you will interact closely with world‑wide CPU RTL designers and implementation teams to investigate and evaluate new micro‑architectural ideas and design trade‑offs that will make the micro‑architecture for the next products successful for the target sectors. You will evaluate these ideas and analyse CPU performance and power, developing and using C++ based models of the micro‑architecture. You will also coach and mentor more junior engineers to help them grow and become deep experts on the field.
Responsibilities
- Help drive the technical direction of the team, which develops, tests and maintains software models of Arm’s advanced CPUs.
- Engage with hardware design engineers to prune the design space of next‑generation products, understanding power and performance opportunities on current processors and investigating potential micro‑architectural improvements.
- Support the mentorship and coaching of other specialists; sharing your technical expertise and experience.
- Assist in continually improving the effectiveness of Arm modelling methodologies.
- Collaborate with performance, design and implementation engineers across the world, communicating and aligning activities related to integration, methodologies, strategies, etc.
Required Skills & Experience
- Good interpersonal skills and capacity to work efficiently with local and remote teams.
- Detailed understanding of CPU micro‑architecture.
- Experience of performance modelling.
- Experience exploring and evaluating ideas and performance related to processor micro‑architecture.
- Proven experience in C++.
Nice to Have Skills & Experience
- Team leadership, including planning and managing tasks, as well as delivery to specification and schedule.
- Strong software development experience, including design specification, coding, testing, and debugging.
- Experience with RTL and SystemC simulators.
- Experience with power models.
- Familiarity with Arm architectures and instruction sets.
- Knowledge of System Architecture and System Software including OS kernel internals.
- Experience of Unix development environment.
- University degree, ideally in electronic engineering or computer science, although other graduates would be considered if they have meaningful experience.
In Return
You will get to utilise your engineering skills to build support for technologies and influence millions of devices for years to come. You’ll share ideas with and learn new skills from some of the best engineers in the world.
