Data Engineer - NESO

National Energy System Operator’s (NESO) strength lies in our people. Together, we’re shaping the future where clean, affordable energy is accessible for all. Every day is an opportunity to make a real difference, accelerating the progress of sustainable GB energy, keeping people connected and society thriving as we create a brighter tomorrow.

As a key Data Engineer, you will be instrumental in revolutionising how NESO's Electricity National Control Centre (ENCC) manages, validates, and leverages real-time operational data.

You will play a critical role in improving how we utilise data, ensuring access and data pipelines are accurate and reliable across the ENCC. This isn't just about data; it's about building the intelligent infrastructure that underpins a greener, more resilient energy system.

You will design and build robust new data connections, enabling NESO to operate a complex, decentralised, and renewable-heavy power system with unwavering confidence.

From developing end-to-end data pipelines and validation frameworks to implementing automation solutions, your work will ensure the accuracy, completeness, and timeliness of critical data – from telemetry and SCADA to market submissions and network parameters.

You’ll also be crucial in identifying gaps in our data needs and working with other teams to assess opportunities to strengthen the data foundation.

Furthermore, you will have significant scope to develop innovative data products by identifying and transforming legacy data, replacing outdated, manual processes with robust, automated solutions.

This role is a unique chance to embed powerful data engineering that eliminates manual errors and drives our digitalisation efforts forward, offering deep insights into real-time operations and the wider energy industry's challenges.

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.

The time to deliver 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.

This role closes on 19th January at 23:59, however we encourage candidates to submit their application as early as possible and not wait until the published closing date as this can vary.

We work towards the highest standards in everything we do, including how we support, value and develop our people. Our aim is to encourage and support employees to thrive and be the best they can be. We celebrate the difference people can bring into our organisation, and welcome and encourage applicants with diverse experiences and backgrounds, and offer flexible and tailored support, at home and in the office.

We're committed to building a workforce that represents the communities we serve, and a working environment in which each individual feels valued, respected, fairly treated, and able to reach their full potential.
