Role Summary - Leyton Orient is building a genuinely data-driven recruitment operation one where statistical rigour, AI tooling, and traditional scouting judgement work in concert rather than in tension. This role sits at the centre of that ambition. As Recruitment Data Scientist, you will design and deploy the models, pipelines, and AI-powered workflows that help our Head of Recruitment and Director of Football identify, assess, and prioritise players. You will work with real data from best-in-class providers, have direct access to senior decision-makers, and crucially have genuine scope to build, not just maintain. This is not a research role. The work you produce will directly influence recruitment decisions, shape squad-building strategy, and be presented to coaches and club leadership. If you want to see your work matter, this is the environment for it.
