    Job Description

    Are you a highly skilled and motivated software engineer with experience of optimizing numerical software? If so, Arm is looking for you to join our world-class team in Manchester working on our maths libraries for HPC and more.

    You will work on all aspects of researching, developing and delivering into the high performance ecosystem for the Arm architecture. You will be part of the team primarily focused on optimization of the Arm Performance Libraries implementations of BLAS, LAPACK and FFT routines. You could also work on the development of high performing open source math.h functions.

    You will strive to improve the computational algorithms used and help develop new features to expand the use of this technology into new and existing markets. This will require innovation and cutting-edge development, working with both proprietary and open source software stacks, on the very latest Arm-based hardware.

    In this role, you'll have the opportunity to learn about and use the world-leading supercomputers that we support. Our tools are used by industry, government and academia to perform cutting-edge scientific research and simulations, such as weather forecasting, modelling the big bang and simulating the human brain.

    Main Duties

    • Optimization of numerical libraries for a range of target Arm-based systems, including improving vectorization and cache performance
    • Improving the parallel performance of the library, allowing greater scalability
    • Investigating, designing, implementing and testing new algorithms
    • Producing and delivering high-quality, reliable libraries to our customers, partners and the community
    • Working with other divisions in Arm to expand support of the architecture

    Job Requirements

    Key Skills & Experience:

    • You are excited by the prospect of delivering added performance to end users by writing high-performing low-level numerical code
    • You have excellent programming skills in C++, C and/or Fortran
    • Strong abstract reasoning skills with an ability to focus on key concepts at all levels of detail
    • You have a strong grasp of algorithms and data structures, and you enjoy applying this to get the best performance out of modern computer systems

    Desirable Skills and Experience:

    The following is a selection of skills used across our projects. You do not need any of these to apply or succeed in your application.

    • Experience in optimization of numerical software
    • Experience with vector architectures and auto-vectorization techniques
    • Experience with parallel programming and parallel runtimes, especially OpenMP
    • Developing for Unix operating systems, in particular Linux
    • Experience of using HPC systems and maths libraries
    • Exposure to large-scale software build, integration and test environments

    Education & Qualifications:

    You will need a good degree (or equivalent) in Mathematics, Computing, or an alternative with relevant experience.

    At Arm, we are guided by our core beliefs that reflect our rare culture and guide our decisions, defining how we work together to defy ordinary and shape extraordinary:

    Passion for progress

    • Our differences are our strength. Widen and mix up your network of connections.
    • Difficult things can take unexpected directions. Stick with it.
    • Make feedback positive and expansive, not negative and narrow.
    • The essence of progress is that it can’t stop. Grow with it and own your own progress.

    Be your brilliant self

    • Be quirky not egocentric.
    • Recognise the power in saying ‘I don’t know’.
    • Make trust our default position.
    • Hold strong opinions lightly.
