Schonfeld — London England
The Role We are looking for a Quantitative Developer to join the Fundamental Equity COO team, embedded directly within the business rather than in a central technology function. You will work alongside quant researchers and COO management to build tools, dashboards, and data pipelines that improve productivity, deepen AI adoption, and make better use of the data the business already has access to. AI integration is a core part of this role, not an afterthought.
We are actively building out how LLMs, agentic workflows, and AI-powered tooling fit into the investment process, and this hire is expected to drive a meaningful part of that. You should come in with both hands-on experience and genuine conviction about where these technologies are heading. The role sits close to the investment process.
We are looking for someone proactive and delivery-focused: someone who identifies what needs to be built, takes ownership, and gets it done without waiting to be directed. The expectation is high-quality output, pragmatic solutions that work in the hands of investment professionals and create immediate value.
