Job description

Join us, be part of more.

We’re so much more than an energy company. We’re 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 doesn’t 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. That’s 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.

About your team:

At Centrica Energy, our mission is to move it.

We’re energy movers by nature. We’re a global renewable energy trading company which helps move energy from source to use – powering businesses, homes, and societies as they transition to a new sustainable energy future. If the idea of working to create a sustainable energy future also moves you, we may very well be the right place for you.

Shape the core platforms that move energy markets. As a software Engineer in Trading Solutions, you’ll build high‑performance .NET services that power trading, post‑trade, and data flows for a business with deep roots in energy markets and a fast‑growing renewables footprint. You’ll work close to the action with traders, analysts, and operations - turning complex market needs into elegant, resilient software. If you’re energized by solving real‑time problems with real‑world impact, this is where you can do your best work.

About the Role

You will be a key engineer in a cross‑functional team delivering mission‑critical software for energy trading and market operations. The work spans order‑to‑cash journeys, real‑time integrations, and data‑rich services that enable confident decisions and reliable settlement outcomes. The role is based in Aalborg where you will:

• Design and implement high‑throughput services and APIs in modern .NET (C#, ASP.NET Core) for trading and post‑trade workflows.
• Integrate with external venues, TSOs/DSOs, brokers, and market data providers; engineer for reliability and observability.
• Drive engineering excellence (CI/CD, automated testing, performance tuning, secure coding) and mentor teammates.

About You

You’re a senior software engineer who thrives on shipping robust software in fast‑moving, data‑intensive environments. You’re comfortable partnering with traders, quants, and operations to clarify requirements and iterate quickly without compromising quality. You bring a product mindset: pragmatic, customer‑focused, and strong on ownership.

• Extensive .NET expertise (C#, .NET 8/9/10), including distributed systems, streaming solutions, and REST/gRPC patterns.
• Deep domain experience with trading platforms and post‑trade processes, including settlements and reconciliation.
• Experience in energy trading (power/gas) and preferably renewables (route‑to‑market, certificates/origination, balancing).
• Proficiency with cloud (ideally AWS), CI/CD, containers, monitoring/telemetry, and secure engineering practices.

The teams manage risk, provide route‑to‑market services for renewable generation, and move energy where and when it’s needed—helping accelerate the transition to a lower‑carbon system.
