A leading Commodities & Energy Trading firm is hiring a C# Front Office Engineer to join a high-impact technology team supporting a mission-critical valuation, risk, and P&L platform used directly on the trading desk.
This role remains open following an extensive search, with strong emphasis on domain knowledge — specifically exposure to options, ideally within commodities (FX options experience also highly relevant).
The business trades across Power, Gas, LNG, Oil, and Environmental products and continues to invest heavily in front-office technology as energy markets grow in complexity and scale.

You’ll operate in a desk-aligned, business-facing environment, working closely with traders, analytics, and risk stakeholders, and taking ownership across the full software lifecycle — from design and development through to production support.
