Senior C# Developer | London, Hybrid

Senior C# Developer | FX Platform | Investment Management | London

We’re partnered with a leading investment management firm with a strong global footprint, currently investing in the build-out of its in-house FX, trading and investment technology platforms. The business operates in a highly data-driven environment where technology plays a key role in supporting investment teams, trading workflows, portfolio decision-making, risk visibility and operational efficiency.

They’re now looking for a Senior C# Developer with strong financial markets experience and a clear understanding of how an FX platform works end to end.

This is not a role focused on one small part of a trading system. The key requirement is someone who understands the complete FX trade lifecycle - how data is sourced, ingested, validated, transformed, consumed and reported across pricing, execution, booking, positions, risk, P&L, portfolio views and downstream systems.

You’ll work closely with trading, investment, risk, operations and technology teams to build and enhance in-house platforms used across FX and wider investment workflows.

This is a strong opportunity for someone who wants real breadth across an investment technology platform, not just working on one screen, one service or one isolated workflow.
