What you’ll need

We are seeking an experienced Data Scientist with proven expertise in understanding complex data requirements across a diverse range of sports. In this role, you will design and implement robust methods to capture, process, and interpret athlete data, applying advanced statistical techniques, coding, and data analytics. You will bring credibility through your experience in data integration, process automation, and visualisation, helping internal and external teams make informed, data-driven decisions.

You will have a strong appreciation for the value of optimising and standardising data workflows, maintaining data integrity, providing technical guidance on data management systems, and developing analytics solutions that generate actionable insights to support organisational objectives.

Working collaboratively with multi-disciplinary teams and sport system partners, you will excel at building trusted relationships and influencing stakeholders to improve data management practices. You will demonstrate curiosity and confidence to challenge existing processes, drive science-based innovation, and continually enhance the design and delivery of data management practices within Teamworks AMS. Your work will directly contribute to a system that supports athletes to thrive and where ‘winning well’ is embedded across the Welsh high-performance system.

How you’ll contribute

Wales is a proud part of the UK high performance system and has achieved unprecedented recent success on the world stage. We want to create the most science-informed sporting system in the world, enabling all athletes in Wales to thrive and making 'winning well' more likely.

We’re clear on the crucial role that the environment can play in improving the experiences of athletes and we want to ensure that athlete development environments in Wales are better than anywhere else. If you’ve got a passion for sport and for helping people to be the best version of themselves then this could be the role for you, and we’d love to hear from you.

You will contribute by working closely with the Teamworks AMS lead to enhance data management processes in addition to applying your experience to other projects that the Sport System Institute Services team are responsible for. You will help to identify, explore, plan and deliver on projects that are aligned to our Institute purpose. You will support our learning around enhancing athlete development across pathways and our sharing of this with everyone that needs to know.

Who you’ll work with

You will need to develop strong relationships with members of the sport system institute services team, wider Sport Wales colleagues, coaches, and other staff in sports to deliver against identified data needs.
