Together with industry, we are creating a cleaner, more sustainable energy future.

We’re looking for a Python Software Engineer to join our Network Topology Optimisation team, helping to develop innovative software that supports smarter operation of the electricity network. You’ll design, develop and enhance existing applications that automate engineering processes, integrate with specialist analysis tools and improve operational efficiency. Working alongside engineers and technical specialists, you’ll develop robust, maintainable code, contribute to new optimisation solutions and help shape the future of our technology. This is an exciting opportunity for someone who enjoys solving complex problems through software development and is keen to learn, innovate and make a real impact.

This role can be based in Wokingham, and we continue to offer hybrid working from office and home with the requirement to be present in the office 1-2 days/week. We are open to full time and part time applicants, as well as flexible working arrangements.

Key Accountabilities

• Design, develop and maintain Python applications and software solutions.
• Enhance and automate engineering processes through innovative software development.
• Develop and improve optimisation algorithms and data processing solutions.
• Integrate applications with specialist engineering software and external APIs.
• Produce well-structured, maintainable and documented code.

About Us

At the National Energy System Operator (NESO), we play a vital role in tackling climate change and securing Great Britain's energy future. We already operate the world's fastest decarbonising electricity system and are working towards our ambition to run it carbon-free for a short period this year - provided the market supplies electricity exclusively from renewable sources. Alongside this, we provide expert advice to government on how to deliver a clean power system by 2030.

In autumn 2024, the Electricity System Operator (ESO) transitioned to become NESO - an independent, expert public corporation with a whole-system view across electricity, gas, and hydrogen. NESO operates independently and transparently, always acting in the best interests of all energy users. Licensed and regulated by Ofgem, we make impartial decisions that balance sustainability, affordability and security. Our organisation is fully independent from government, the regulator and all commercial interests, with a clear focus on system-wide benefit, long term thinking and public value.

The time to deliver is now. Join the energy transformation and help shape the future. Your energy. Our future. Together.
