Senior Quantitative Developer – Research Team – Systematic Fund – London – Hybrid – Up to £500k TC

My client is a multi-billion dollar multi-strategy firm hiring a Senior Software Engineer into its front-office engineering group in London. The work is greenfield: portfolio management platforms, order workflow, intra-day position and P&L modelling, trade lifecycle, and the execution and analytics layer underneath all of it. Systems that sit in front of live capital and can't be wrong.

The engineering culture is small, senior, and autonomous. You gather requirements directly from PMs and traders, make the architectural call, and own the outcome end to end. There's no requirements handoff and no architecture committee. The expectation is that you operate as a technical peer to the investment teams, not a service provider.

The bar is deep production C# and .NET, comfort with performance-sensitive systems, and a track record of owning what you ship in live environments. Experience in financial markets across execution, position management, or risk is a real advantage. The firm is hiring for engineering depth and domain instinct, not one or the other.

Comp is up to £550k TC. Worth a conversation if you want to own something that matters.
