.NET Developer | C# .NET Energy Trading | Front Office Risk | Position Management | Azure | Up to £750/day Inside IR35 | 3 Days in Office | London
We are partnering with a leading organisation in the wholesale energy trading sector, operating across Power, Gas, Renewables, and Environmental markets. The business is at the forefront of energy trading technology, developing sophisticated platforms that enable traders and risk teams to monitor positions, understand market exposure, and make informed trading decisions in real time.
They are looking for a C# .NET Software Engineer to join their Front Office Risk technology team, working on the firm's Unified Position Management (UPM) platform. This is a business-critical application responsible for consolidating trading positions across multiple asset classes, providing traders and Front Office Risk with an accurate, real-time view of positions, P&L, and market exposure.
This isn't a maintenance role. You'll be enhancing and evolving a strategic platform that sits at the heart of the Front Office technology landscape. Working alongside traders, risk managers, and quantitative teams, you'll build scalable solutions that improve how trading positions are captured, aggregated, validated, and analysed across increasingly complex energy markets.
What makes this role unique is the complexity of managing position and risk data in real time. Every trade, amendment, lifecycle event, and market movement can alter exposure across multiple books and portfolios. Your software will process these events with precision, ensuring positions remain consistent, risk calculations remain accurate, and business users have complete confidence in the data driving trading decisions.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
In this role, you'll help evolve a modern, event-driven C# .NET platform capable of supporting growing trading volumes and increasingly sophisticated Front Office workflows. You'll contribute to the design of scalable services that process trade events, calculate position changes, distribute real-time updates, and integrate with downstream risk, pricing, and reporting platforms. Success requires strong engineering principles, asynchronous programming expertise, and an appreciation for building deterministic systems where data accuracy is paramount.
You'll bring experience developing high-performance C# .NET applications within Front Office technology, ideally across Energy Trading, Commodities, or Capital Markets. Whether your background is Position Management, Risk, P&L, Market Data, or ETRM, you'll understand the importance of delivering resilient, scalable platforms that support business-critical trading operations while balancing performance, maintainability, and long-term architectural evolution.
