Job description

Do you want to build AI and data science solutions that directly influence high-value business decisions?

Have you taken models from exploration through to production in real environments?

Are you ready to work in a small, high-impact team with real ownership and autonomy?


This organisation is a global investment firm operating at the intersection of technology, data, and decision-making. They have built an internal data and technology function to support deal sourcing, due diligence, and portfolio insights, using modern data science and emerging LLM/NLP techniques. The team works closely with senior stakeholders and operates like a lean product and research group within a fast-paced commercial environment.


They are hiring a Data Scientist (2+ years of experience) to join their London team. This role offers exposure across research, production deployment, and short-form analytical projects, with genuine end-to-end ownership rather than narrow modelling work.
