Graduate programme – Data & Performance - Wales
There is no sponsorship for this opportunity and if you are an applicant on a Student Visa, I'm afraid this role will not consider you for interview.
Location
Dinorwig Power Station, Llanberis, North Wales. This is an on-site role based at one of the UK's most impressive pumped-storage hydroelectric facilities.
Launch your career at the intersection of data, engineering and energy. This opportunity sits within a major UK energy business operating critical energy storage assets. You’ll play a hands-on role in improving how data is captured, analysed and used to drive performance across industrial sites.
This is a structured 24-month graduate programme designed to build strong analytical capability across the full asset lifecycle. You’ll work with large, real-world datasets to support operational decision-making, improve efficiency and help optimise plant performance over the long term.
What you’ll be doing
- Supporting the development and maintenance of a high-quality data ecosystem across energy assets
- Collecting, cleansing and validating large datasets to ensure accuracy and usability
- Building dashboards, analytical models and reports to monitor performance
- Conducting trend analysis and generating early insights to support operational decisions
- Assisting with performance investigations and identifying root causes of issues
- Collaborating across engineering, operations and commercial teams to deliver data-driven insights
- Supporting the automation of reporting and contributing to data pipelines and scripting
- Communicating insights clearly to both technical and non-technical stakeholders
