Job summary

At the forefront of protecting energy consumers, Ofgem is building smarter, greener technology to power a low-carbon future. We’re looking for a Junior Software Developer to join us and help combat the challenges of legacy tech and drive the evolution of our cloud-based digital services.

Ofgem is Great Britain’s independent energy regulator. We’re at the forefront of change across the energy sector, driving toward Net Zero whilst protecting energy consumers, especially vulnerable people.

We’re offering a permanent opportunity that’s ideal for someone looking to kick-start or reshape their career in software development. This role offers experience across a wide range of technologies and applications, from working with legacy systems to contributing to modern cloud-based platforms. From day one, you’ll join a collaborative digital team, gaining exposure to real-world projects.

We’re looking for someone who’s naturally curious and keen to learn. You might be a graduate, a career changer, or someone returning to tech, but what matters is your enthusiasm, your willingness to solve problems, and your ability to work well in a team. If you have a basic understanding of C#.NET, SQL, or debugging tools, we’d love to hear from you.

You’ll be part of a relaxed, welcoming team made up of people from varied backgrounds with different working styles - authenticity and collaboration are at the heart of how we work. Based in Glasgow, London or Cardiff, we offer hybrid working, a supportive environment and opportunities to grow your skills in a way that suits your ambitions.

Our Digital Delivery Team have a critical purpose to build and maintain digital solutions that help us on our vital mission to protect consumers and accelerate Net Zero. In this role, you’ll be part of that mission, contributing to systems that support environmental programmes and energy reform across the UK.
