Warwick, GB, CV34 6DA

Division:  Delivery Services

Job Function:  Information Technology

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 Energy Future System Operator

As you may have seen the Government and Ofgem have asked the ESO to take on new roles and responsibilities to help deliver net-zero.

Becoming the Energy Future System Operator is a critical step to help deliver a reliable and clean energy transition for all. The ESO, including all of its existing roles, will be at the heart of the new Future System Operator, taking on additional roles with a whole energy system mindset to drive progress towards net zero while maintaining energy security and minimising costs for consumers.

The new organisation 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 but funded by consumers through price control agreements. It is anticipated that the new organisation will be up and running by or in 2024.
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 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.

We’re excited and proud of the role we are playing in the decarbonisation of the energy system so come join us, at ESO Technology, on our truly transformative journey to help shape the future of energy and bring it to life.


This Solutions Architect role is based at either our Warwick or Wokingham offices, both of which have free onsite parking, and we continue to offer hybrid working from office and home. It should be noted that there is an on site Project meeting in Warwick on Tuesdays (subject to change).
