Finance Portfolio Analytics Manager

At GSK we unite science, technology and talent to get ahead of disease together. Deciding which R&D projects to invest in — and how to sequence, resource and prioritise them — is one of the most consequential judgements we make. The Portfolio Data Science team turns scientific, clinical, operational and financial inputs into the analysis and insight that guide those investment decisions across short-, medium- and long-range horizons. Position Summary Reporting to the Head, Data Science, Analytics, and AI, the Finance Portfolio Analytics Manager builds and leads the analytical capability that underpins R&D portfolio and investment decision-making. You will design the models, frameworks and dashboards the team relies on, and lead ad hoc strategic analyses that answer complex, high-stakes portfolio questions — translating scientific and clinical information into quantified investment and financial impact. This is a senior individual-contributor role. You will not have direct reports, but you will act as the analytical lead for portfolio analytics — setting standards, guiding and mentoring analysts, and being the trusted partner senior stakeholders turn to for rigorous, decision-ready analysis.
