Job Purpose:

UK Power Networks Distribution System Operator (DSO) is ensuring the net zero transition for all. The DSO is harnessing data to unlock huge amounts of value to critical players in the energy sector, such as large renewable energy developers and generators, flexibility markets, local authorities, connections specialists, the National Energy System Operator, academics and others. Our role is to help everyone to participate in the future of energy.

The Data Science & Development Team plays a quintessential role in unlocking the wider DSO goals, with products in the control room unlocking network capacity and avoiding curtailment of renewable generation, to customer-facing web apps helping the public understand the potential of their new connections' opportunities. We work fast and bulldoze our way through traditional thinking. In our first 2 years of operations, UK Power Networks has been rated as the #1 DSO in Great Britain by Ofgem; UK Power Networks Smart Grid capabilities (now the DSO) has been rated top 3 in the world since 2018 in the global Smart Grid Index rankings, most recently coming 2nd in 2024.

The nature of this role is varied because the energy sector landscape is evolving. One week you may work analysing the Flexibility Markets using smart meter data to unlock street level voltage issues; the next you might work on The Connections Lab web-app front end unlocking insights for developers to build the country's future renewable energy generation. We adapt to external partner feedback, capitalising on the best value we can offer to the energy sector with our time. The DSO has high-performance compute nodes running slurm in both the control-room and the reserve control room to test and deploy our code, with punchy local development laptops and remote desktop access to some powerful workstations.

You should join UK Power Networks DSO if you want to improve the UK's net zero transition. The projects delivered by this small team have unlocked more efficient use of renewable generation, shaped multi-million-pound investment decisions, and strengthened the flexibility market. If you value variety in your work, the autonomy to influence outcomes, and the recognition of contributing to a world-class distribution network, this role is for you.
