(Senior) Grid Connection Engineer
Permanent - Full TimeJob Overview
Your Mission
This is an excellent opportunity to accelerate the deployment of battery energy storage across the GB transmission and distribution networks, supporting the transition to Net Zero. You will join one of the UK’s fastest-growing battery storage developers, owners and operators, working alongside a team of industry specialists and project delivery professionals.
You will play a key role in developing Field’s portfolio of battery energy storage projects, from early-stage design and value engineering through to delivery and commissioning. Our projects are large-scale, high-value and at the forefront of the energy transition.
This is a highly collaborative role, working closely with the Origination team, Project Developers, Project Managers and Project Engineers, as well as the Corporate Development team. You will report to the Senior Project Development Manager for Grid Connections and be supported by internal specialists across health and safety, grid code, BESS technology, planning, procurement, legal and commercial management.
With four projects currently in construction and a rapidly expanding pipeline, you will also have the opportunity to help shape the engineering strategy and delivery processes of a fast-growing project delivery team.
