Job Introduction
The GB energy system is undergoing a rapid and unprecedented transformation as we work towards Clean Power by 2030 and Net Zero by 2050. The distribution network sits at the heart of this shift, enabling the connection of thousands of electric vehicles, heat pumps, and significant volumes of new solar and wind generation. To meet this challenge, we’ll be expanding and reinforcing our network at a scale not seen this century.
As one of the UK’s Distribution Network Operators, we play a critical role in the Great Grid Upgrade—supporting the delivery of accelerated strategic Transmission Investment (ASTI) projects across England and Wales. These major infrastructure upgrades are essential to meeting the nation’s future energy needs.
We now have an exciting opportunity for a Project Engineer (Senior Authorised Person) to join our newly formed ASTI Projects team within Field Operations. In this role, you’ll be working at the forefront of our major projects programme, helping to deliver high-impact infrastructure that will support the energy transition for decades to come.
Reporting to a Senior Project Manager, you’ll provide specialist engineering expertise across ASTI projects up to and including 132kV. You’ll work closely with Project Managers to deliver a wide range of activities including scoping and development, design reviews, installing and commissioning assets while ensuring our work meets the highest standards of safety, quality, and compliance.
This hands-on role also includes managing contractors, supporting network operations, shaping policies and technical practices, and driving continuous improvement. As a trusted technical expert, you’ll work with colleagues, customers, and a variety of external stakeholders, all while helping to develop and mentor others within the team. It’s a unique opportunity to influence the future of our network and play a part in the UK’s energy transition.
We offer flexibility on location, with the role based from any NGED depot within our licence areas: East Midlands, South West, West Midlands or Wales—agreed with the successful candidate.
