Senior Software Developer - OFGEM - G7

Help shape the future of energy through impactful digital solutions. Ofgem is looking for two Senior Software Developers to support the delivery of green energy and social schemes, using modern technologies to build services that make a real difference to people’s lives. 

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 permanent roles where you’ll contribute to the development of applications that support some of the UK’s most vital public services. This is a high-impact opportunity to influence how digital tools are built and delivered, ensuring the systems behind our schemes are efficient, secure and user-focused. 

You’ll develop and support innovative applications that contribute to green initiatives, as well as taking in part in the technical development of projects and implementing new technologies. There’s plenty of scope for application development, process improvement and shaping the way we work within an agile delivery environment. 

This senior development role will also give you the chance to support junior colleagues, using your expertise to guide and mentor them, and step up and take on management activities for various projects. Collaboration will be at the heart of your approach as you work with other developers, stakeholders and digital experts to create scalable, sustainable solutions that meet Government Digital Service (GDS) standards. 

We’re looking for someone with strong experience in Microsoft-based development, including C#, Entity Framework Core and SQL Server, along with a solid understanding of Azure. You’ll be familiar with applying design patterns, writing and executing unit tests, and working within microservices architectures. Experience with containerisation tools such as Docker and Kubernetes, and the ability to communicate effectively across technical and non-technical audiences, will be key to success in this role. 

At Ofgem, you’ll be part of a collaborative, inclusive environment where your ideas are valued and your expertise can flourish. We support hybrid working, offer an exceptional benefits package and provide the flexibility and development opportunities that will see you advance your career. 

We have a critical purpose to deliver smart, efficient digital services that power the UK’s clean energy future. You will help ensure that essential schemes are built on strong technical foundations, enabling fairer, greener outcomes for consumers and communities across the country.
