At GSK, we see a world where advanced applications of Machine Learning and AI empower us to drive groundbreaking solutions that further our mission of enabling everyone to do more, feel better, and live longer. This ambitious vision will rely on developing cutting‑edge products and solutions in Machine Learning and AI.

The AI Finance and Strategy team focuses on creating full‑stack, AI‑powered tools to support the R&D drug development strategy at the highest level of GSK. By leveraging data from across the organisation and beyond‑ from clinical trial readouts to external market analyses‑ as well as innovative methods – reinforcement learning, agentic systems, ML forecasting – we improve financial strategies and optimise decision‑making.

We’re looking for a highly skilled AI/ML engineer to help us make this vision a reality. Competitive candidates will have a track record of writing and shipping quality, well‑documented and well‑tested software, as well as demonstrated expertise in complex mathematical modelling and AI/ML development. Candidates should be comfortable with modern, cloud‑native computing, and with continuous development and production deployment on cloud platforms to large user populations.

We’re looking for a passion for advancing financial and strategic solutions that align with GSK’s mission, along with a commitment to continuous learning and development.

The AI/ML team is built on the principles of ownership, accountability, continuous development, and collaboration. We hire for the long term, and we’re motivated to make this a great place to work. Our leaders will be committed to your career and development from day one.
