The Role

This includes an in‑house C# PnL and Risk system that performs real‑time portfolio valuation, alongside other components that will be integrated into a cohesive, modernised core platform.
You will work closely with senior stakeholders including the CTO, COO, Head of Operations, and Project Management.
