About the role

The UK has set out its ambition to be net zero by 2050 and the energy industry is responding – together we are building a cleaner, greener Britain.

The Energy System Operator (ESO) are now looking for an Enterprise Security Architect, reporting to the Head of Strategy & Architecture. You will develop and maintain our security architecture, whilst bringing cyber security to life and helping to drive a security-focussed culture. The role will work with both the Chief Information Security Officer and Enterprise Architecture functions to define a security architecture not only for a new independent organisation, but also one fit for our transformative future. 

This role can be based from Wokingham or Warwick, 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.
