My client is a global electronic market maker. The systems make markets across millions of instruments simultaneously. Every microsecond of latency has a measurable impact on fill quality.

Every system failure has a direct P&L consequence. The engineering bar is correspondingly serious.

The work spans low-latency execution infrastructure, real-time pricing and risk systems, and ML inference inside hard latency budgets. That means FPGA-accelerated processing, kernel bypass networking, sub-nanosecond profiling, distributed systems at extreme throughput, and deploying models into production where determinism and latency are hard constraints. The finance domain is learnable. The engineering instincts are what they're actually hiring for.

Strong engineers get ownership of critical systems quickly and direct exposure to production consequences from day one. The intellectual environment is drawn from the top of systems engineering, mathematics, and physics globally. Engineering is not a support function here. It is the core competency of the business.

Deep C++ and Python, a track record of building performance-sensitive systems, and the kind of rigour that comes from working in environments where being approximately right isn't good enough.

Comp is up to £550k TC. One of a very small number of roles where the technical frontier and the production environment are the same place.
