Senior Backend Engineer (L5) - Core trading

About the role

We're hiring a Staff Engineer to own the architecture of OpenFX's trading and hedging core — the systems that price a client's trade, execute it, and manage the risk we take on as a result. Trading owns the client's entire trade experience — quote generation, pricing strategy, the spread engine, and the trade lifecycle across GUI, API, and soon conversational AI.

What you'll do

• Own the architecture of the Client Trading Engine, Pricing Engine, Risk Management Engine, and Smart Hedging
• Break complex, ambiguous systems into smaller components with clear contracts, clear scope, and independent deliverability
• Set and drive the architectural vision for trading and hedging, and take large architectural bets through to completion
• Build for scale — design systems that hold up as volume, venues, and currency corridors grow
• Own the observability standard across all components, so the behaviour of the trade and risk path is legible when it matters

What you need

• 7–12 yrs of experience
• Design systems
• Any graduate
