Senior Data Engineer

Join Ofwat’s Data Platform Services Team as a Senior Data Engineer

*Office Location: Birmingham (B5 4UA) with hybrid working*

About Us

We are Ofwat, the Water Services Regulation Authority, a non-ministerial government department responsible for regulating the water sector in England and Wales. Following the Independent Water Commission’s final report, the UK government has set out a bold new direction - one that brings together expertise from across the sector to deliver better outcomes for customers and the environment.

We are working in collaboration with the government and other regulators to help establish a new body for England, combining our strengths with those of the Drinking Water Inspectorate, the Environment Agency, and Natural England. We’re also continuing to engage with the Welsh Government to support future decisions for Wales.

While these changes take shape, our mission remains the same: to hold water companies to account, drive performance, and ensure the sector delivers real value for customers, communities, and the environment. If you’re passionate about making a difference, this is a unique moment to join us and help shape the future of water, and together we can continue to make a positive impact.

The Role

The Independent Water Commission published their final report on the review of the water sector regulatory system on 21 July 2025. While we are entering a period of change, Ofwat still has a lot of important work to do. We remain focused on the day job and ensuring that the £104 billion investment package that we have approved delivers the maximum benefits for customers and the environment. Ofwat remains committed to working constructively with the government and supporting outcomes that are in the best interests of customers, communities, and the environment. Our focus remains the same: delivering strong, independent economic regulation to deliver our vision of a secure and sustainable water sector, acting in the best interests of customers, communities and the environment.

The creation of the new regulator may take up to two years to finalise, during which time we will work closely with the government and other regulators to create a plan for a smooth transition.
