Join us, be part of more.  

Were so much more than an energy company. Were a family of brands revolutionising how we power the planet. We're energisers. One team of 21,000 colleagues that's energising a greener, fairer future by creating an energy system that doesnt rely on fossil fuels, whilst living our powerful commitment to igniting positive change in our communities. Here, you can find more purpose, more passion, and more potential. Thats why working here is #MoreThanACareer. We do energy differently - we do it all. We make it, store it, move it, sell it, and mend it.

As a Senior Software Engineer at Centrica Energy, you will play a key role in designing, building, and evolving the technology platforms that support our power trading operations. Working within a highly skilled agile team, you will combine hands-on software engineering with technical leadership, helping to shape architecture, drive engineering best practices, and mentor fellow developers.

This is an opportunity to work on business-critical systems in a fast-paced, data-driven trading environment where technology is a key enabler of commercial success.

This role can be based out of our Aalborg, Denmark office.

Your responsibilities will include:

• Leading the design, development, and enhancement of robust backend services and APIs using .NET C#

• Driving technical architecture decisions and ensuring solutions are scalable, secure, and maintainable

• Building and enhancing desktop applications using WPF and integrating systems via Web APIs

• Championing engineering excellence through code reviews, automated testing, and continuous improvement of development standards

• Leveraging AWS Cloud and Kubernetes to deliver resilient, cloud-native solutions

• Designing and optimizing data solutions using MongoDB, PostgreSQL, and MSSQL

• Implementing and supporting event-driven architectures using RabbitMQ and Kafka

• Enhancing observability through monitoring, alerting, and logging with Datadog

• Driving CI/CD best practices using Jenkins, Octopus Deploy, and Argo

• Collaborating across teams using Git, Jira, and Confluence

• Working closely with traders, analysts, and business stakeholders to understand requirements and deliver high-impact solutions

• Mentoring and supporting less experienced engineers, fostering a culture of collaboration, learning, and continuous improvement

• Contributing to the technical roadmap and helping shape the future direction of our platforms and engineering capabilities.

We understand the importance of a smooth transition, which is why we offer an extensive onboarding programme tailored to your needs. You will be paired with a dedicated buddy and supported by experienced colleagues who will help you quickly build domain knowledge and establish yourself within the team.
