Software Engineer | C# .NET Energy Trading – ETRM Architectural Redevelopment
Azure | Up to £900/day Inside IR35 | 3 days in office (Hybrid) | London
We’re partnering with a leading global financial services organisation specialising in providing liquidity, market access, and infrastructure for commodities, financial markets, and foreign exchange.
The client operates across multiple international markets, combining developed industry expertise with innovative technology to serve clients—including institutional investors, banks, corporations, and professional trading firms with tailored solutions.
About the Role
They are looking for a C# .NET Software Engineer to join their Power and Gas team for a critical overhaul of their Front Office ETRM trading platform. This is not a maintenance role—you will be driving the architectural redesign of their C# .NET-based ETRM system, underpinning the high-performing trading desk.
As the key technical authority, you’ll own a low-latency C# .NET trading platform, operating across Power and Gas markets. The uniqueness of this platform lies in its cause-and-effect dynamic: every change triggered by your code directly impacts the market, which immediately feeds back into the system. This requires real-time engineering judgment, handling asynchronous events, safe state mutation, and deterministic behaviour under volatility.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- Full-stack architectural transformation of a C# .NET ETRM platform, aligning it with event-driven best practices and high-frequency trading requirements.
- Design and implement a scalable, low-latency C# .NET trading system supporting:
- High-concurrency user workflows
- Complex P&L logic
- Execution management
- Risk recalculation in real time
- Redesign the platform to replace its monolithic limits—scaling to support multiple Front Office traders interacting with live market data.
- Drive the adoption of event-driven architecture (Kafka / Solace) for deterministic workflows with zero downtime thresholds.
- Craft high-throughput messaging pipelines optimised for low-latency order book events while maintaining real-time P&L and audit integrity.
- Collaborate with Front Office traders, quants, and quant risk teams to ensure technological solutions are market-relevant, resilient, and optimize decision-making under stress.
- Balance performance, scalability, and maintainability with SOLID design principles and Clean Architecture.
Requirements
Technical Deep Dive
- 8+ years in high-performance C# .NET environments, with specific experience in:
- Building P&L, risk, pricing, or ETRM trading systems within Energy Trading (Oil & Gas, Power, Emissions).
- Real-time financial systems where latency, correctness, and determinism are critical.
- Event-driven C# .NET architectures using:
- Kafka/Solace for high-throughput, event-sourced workflows.
- gRPC and REST APIs as backbone for service integration.
- Low-latency reasoning in high-volume message processing, with strong SQL Server optimisation (contention resolution, indexing for audit trails and trade books).
