Job Function:  Information Technology

About the role

Great Britain's electricity system is undergoing an ambitious, exciting and vital transformation. Together with industry, we are creating a cleaner, greener system, one that protects the planet and serves generations to come.

The Energy System Operator (ESO) are now looking for a Solution Architect, to operate within the “Strategy & Architecture” pillar of the ESO organisation and to work within the Commercial & Markets Domain. They will play a key role in the design, implementation, evolution, and integration of the systems in support of the business needs around new markets/products in particular.

This role can be based from Wokingham and we continue to offer hybrid working from office and home.

About us

As Great Britain’s electricity system operator (ESO), we sit at the heart of the electricity system, using our outstanding engineering and commercial expertise to balance electricity supply and demand. Ultimately, we keep the electricity flowing directly to where it’s needed, second by second.


Becoming the Future System Operator
In 2021, government and Ofgem jointly consulted on proposals for an expert, impartial Future System Operator (FSO) with responsibilities across both the electricity and gas systems, to drive progress towards net zero while maintaining energy security and minimising costs for consumers. In October 2023, the Energy Act 2023 was passed, legislating for this Future System Operator to be created.  

The ESO, including all of its existing roles, will be at the heart of the new Future System Operator. We will be taking on additional roles across vectors and sectors to create an organisation with a whole energy system mindset; enabling us to identify solutions to our energy system that are more sustainable, secure, and affordable for all.  

The FSO will be set up as a public corporation with operational independence from government – bringing parties together to support optimised decision making and action. As now, it will be licenced and regulated by Ofgem through price control agreements. It is anticipated that the new organisation will be up and running in 2024.

The time to act on climate change is now. As part of our team, you won’t just be touching the lives of almost everyone in Great Britain – you’ll be shaping the way we use and consume energy for generations to come.
