Full Stack Developer | C# .NET | Angular | Power Operations | £95,000 | Azure | Energy Trading | Hybrid, London

A Full Stack C# .NET Developer is required to join a high‑performing Power Operations technology team, working on a mission‑critical post‑trade application that supports all power trading activity across the organisation.

This is a full stack development role with strong emphasis on C# .NET, Angular, and modern cloud‑based engineering. You’ll work on a business‑critical post‑trade system, developing new features, enhancing existing functionality, and ensuring stability, scalability and long‑term maintainability.

The team is entering a new phase of growth under refreshed technology leadership, moving away from contractor dependency and investing in permanent engineering capability. This hire is a key part of that strategy a long‑term, mid‑level developer who wants to grow inside a modern energy trading environment.

The Team

The Power Operations IT Delivery team sits at the centre of the post‑trade ecosystem, responsible for:

• Power trade capture and post‑trade workflows
• Operational controls across scheduling, nominations, confirmations and settlements
• C# .NET backend services powering mission‑critical trading processes
• Angular front‑end applications used by traders and operations teams
• Data‑driven workflows across SQL Server, Oracle and Azure
• Trade lifecycle tooling supporting multi‑asset energy products

The application you’ll join is a relatively new C#/.NET + Angular system, currently supported by two developers. You will become the third engineer, contributing to a significant pipeline of enhancements, new features and long‑term platform evolution.
