    Job Description

    Would you like to join the team that defines the micro-architecture of the future Arm CPUs, and influence the future by creating products that millions of people will use all over the world? We are looking for engineers willing to accept the challenge of growing our modelling and performance analysis capability and explore ideas that will fuel very successful products, as well as building and supporting initiatives that will improve our methodologies and perform wider and faster explorations of the CPU design space.

    The performance modelling 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 the CPU RTL designers 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 analyze CPU performance developing and using C++ based performance 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.

    Job Purpose

    The key objectives of this role include:

    • You will help driving the technical direction of the team, which develops, tests and maintains software models of Arm's advance CPUs.
    • You will engage with hardware design engineers to prune the design space of next generation products, understanding performance opportunities on current processors and investigate potential micro-architectural improvements.
    • You will chip in with the development, test and maintainability of the software performance models for Arm’s advanced CPU and system level IPs, making them flexible and robust to enable the effective exploration of future products.
    • You will support the mentorship and coaching of other specialists; sharing your technical expertise and experience.
    • With your help, we will keep improving the effectiveness of Arm modelling methodologies.
    • We are closely interacting not only with hardware designers but also with other CPU performance modelling teams across the world. You would be involved on the communication and alignment of activities related to integration, methodologies, strategies, etc.


    Job Requirements

    Education & Qualifications

    You will have a good university degree, ideally in electronic engineering or computer science, although other graduates would be considered if they have meaningful 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 of exploring and evaluating ideas and performance related to processor micro-architecture.
    • Proven experience in C++.


    • 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.
    • Familiarity with Arm architectures and instruction sets.
    • Knowledge of System Architecture and System Software including OS kernel internals.
    • Experience of Unix development environment.
