Your world of expertise

As a HPC Optimisation Scientific Software Engineer you will contribute to the development, support, and optimisation of large-scale parallel climate and weather applications on HPC systems.

We are currently in a major push to develop our Next Generation Modelling Systems, to help exploit our new world-leading supercomputer capability and to support our adoption of data science (specifically artificial intelligence and machine learning) across our national capability, and you will be working towards these objectives in some form.

The Scientific Software Engineer (SSE) role is a varied one, with many opportunities for development, progression and finding new challenges both within the SSE career family and beyond.

Being a Scientific Software Engineer is about far more than just technical skills – you will need to be able to work alongside colleagues in a range of areas, both technical and scientific. We frequently require our SSEs to collaborate internally and internationally.

• Analyse and optimise the performance of large-scale scientific applications.
• Benchmark scientific applications on current and future supercomputer hardware.

Support the analysis and tuning of operational scientific workloads on the supercomputer, working with the teams responsible for those workloads.

• Support users in diagnosing and resolving HPC performance and technical issues

Develop novel software, tools and methods to improve the performance, scalability and portability of large-scale scientific applications on current and future HPC architectures.

• Collaborate with and provide technical expertise to scientific and technical colleagues in the development and improvement of HPC applications.
• Maintain, extend and share expertise in optimisation tools, parallel programming techniques and algorithms, and current and future supercomputer capabilities.

Our work is life-changing, often life-saving and always life-enhancing.
