Description:
About The Role
National Energy System Operator (NESO) recognises the potential of bright and talented individuals, and we encourage you to join us as Great Britain’s energy system undergoes an ambitious, exciting, and vital transformation. Together with industry, we are creating a cleaner, more sustainable energy future.
As the Customer Segmentation & Advocacy Manager, you will lead the development and ongoing management of customer segmentation and value-based models that provide the business with a clear, actionable understanding of the customer base. Your expertise will enable a shift from product-led approaches to a more nuanced, customer-centric view — joining the dots across customer activity, feedback, and insights to uncover emerging risks, growth opportunities, and service gaps.
You will own segmentation strategy, ensuring it is grounded in robust data and enriched by targeted outside-in insights gathered from a network of customer advocates and internal feedback channels. This role plays a critical part in driving customer closeness by helping the business to better understand and act on evolving customer needs across horizontal and vertical dimensions.
This role can be based from Wokingham or Warwick and we continue to offer hybrid working from office and home. We are open to full time and part time applicants, as well as flexible working arrangements.
About Us
National Energy System Operator’s (NESO) mission is to facilitate the decarbonisation of Great Britain’s energy network and ensure the delivery of reliable, affordable, and clean electricity for consumers. We work with stakeholders across the whole energy industry to plan for future network needs, using a wider adoption of technology and changes in consumer behaviour, as well as ensuring we have the right markets, networks, and frameworks in place, to transform the way we operate tomorrow.
Join us, and let’s energise progress.
energy, our future, together.
About The National Energy System Operator (NESO)
In Autumn of 2024, the ESO transitioned to National Energy System Operator, or NESO for short. Previously denoted as the Future System Operator (or FSO), the new National Energy System Operator is the independent body responsible for planning Great Britain’s electricity and gas networks and operating the electricity system.
The ESO, including all of its existing roles, are now at the heart of the new National Energy System Operator. As NESO, we will build on our existing roles, capabilities, and ways of working significantly to create an organisation the energy system and its users’ need. Our new capabilities will enable us to look across vectors, including electricity, natural gas and hydrogen, and crucially consider the trade-offs between them.
The organisation is set up as a public corporation with its own Board of independent directors, with complete operational independence from government, the regulator and any and all commercial interest. As was the ESO, NESO will be licenced and regulated by Ofgem through price control agreements and obligated to identify optimal solutions to system operations and planning in the most sustainable, affordable and secure way for all.
