A leading systematic investment team is spinning out from a globally recognised hedge fund into an independent firm already managing $6bn AUM, with ambitions to become one of the largest quant spinouts in the industry. They are hiring senior Quantitative Developers / Research & Data Engineers in London to help build the core infrastructure of the new platform. The environment combines the backing, leadership, and track record of an established fund with the speed, ownership, and technical culture of a high-performing startup.

The CTO personally reviews candidates and expects exceptional technical and communication skills. The role covers areas such as real-time market data systems, quantitative research infrastructure, cloud-based simulation platforms, trading execution environments, and tooling for new strategies and asset classes. The stack is primarily Python with C++, across cloud and on-prem infrastructure. Candidates must have strong buy-side or equivalent high-performance engineering experience, deep Python and good C++ skills, quantitative understanding, and the ability to own major technical initiatives.

Strong academic backgrounds from top universities are required. Compensation is highly competitive, with London base salaries from £120k - £160k and total compensation commonly ranging from £450k to £600k depending on impact and seniority. Four days in-office, Mondays remote. This is a rare opportunity to join a major quantitative trading spinout before the transition completes - at the stage where early hires help define the future platform and culture.
