We are partnering with a leading global financial services organisation that provides liquidity, market access, and infrastructure services across commodities, financial markets, and foreign exchange. Operating in multiple international markets, the business combines deep industry expertise with innovative technology to deliver exceptional solutions to a diverse client base, including institutional investors, banks, corporations, and professional trading firms.
Role Overview
They are looking for a C#.NET Software Engineer to join their Power and Gas team for a crucial restructuring of their Front Office ETRM trading platform. This isn’t a maintenance role—you will be driving a major architectural redesign of a C#.NET-based ETRM system that underpins a high-performing trading desk. You will act as the key technical authority, taking ownership of a low-latency C#.NET trading platform operating across Power and Gas markets.

Key Responsibilities
- Own the full-stack restructuring of a low-latency ETRM platform, applying deep C#.NET architectural expertise to deliver a real-time, event-driven trading system.
- Design a scalable C#.NET trading architecture capable of supporting increased user concurrency, complex pricing logic, P&L workflows, and execution management as the desk expands across Power, Gas, and Emissions trading.
- Evolve the current legacy C# ETRM platform into a resilient, event-driven C#.NET trading system capable of supporting multiple Front Office traders interacting with live market data, reacting to execution events, and recalculating P&L and risk in real time.
Requirements
- Front Office Pedigree: 8+ years in high-performance C#.NET environments, specifically building P&L, Risk, Pricing, or ETRM trading systems within Energy Trading.
- Messaging Expertise: Deep experience with high-throughput messaging systems (Kafka / Solace), implementing asynchronous, event-driven C# architecture patterns, and handling real-time state mutation.
- Architectural Leadership: Proven ability to design and build scalable C#.NET trading platforms while maintaining clean architecture, SOLID principles, and long-term maintainability.
- Database Fundamentals: Strong SQL Server experience managing high-volume trading data, audit trails, trade capture, and real-time reporting within an ETRM or Energy Trading platform.
- Communication: Ability to work closely with Front Office stakeholders, traders, quants, and technology teams to define and architect scalable C#.NET ETRM solutions aligned to business growth.
