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 most important question at the highest level: which drugs to develop and when. By leveraging data from across the organisation and beyond — from clinical trial readouts to external market analyses — we improve financial strategies and optimise decision‑making. We're looking for a highly skilled software 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. Candidates should be comfortable with modern, cloud‑native computing, and with continuous development and production deployment on cloud platforms to large user populations.

The AI/ML team is built on 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.

Responsibilities

• Back‑end development for a Python web application
• Integration of AI/ML components with front‑end, back‑end, data and compute infrastructure
• Responsible for high‑quality software implementations according to best practices, including automated test suites and documentation
• Develop, measure, and monitor key metrics for all tools and services and consistently seek to iterate on and improve them
• Participate in code reviews, continuously improving personal standards as well as the wider team and product
• Liaise with other technical staff and data engineers in the team and across allied teams, to build an end‑to‑end pipeline consuming other data products

Basic Qualifications

• Bachelor's degree in a relevant field (including computational or numerate), or equivalent experience
• Demonstrated experience of Python backend development (e.g. using FastAPI)
• Cloud experience (e.g. Azure preferred) including core web application infrastructure
• Strong skills in Python
• Unit testing experience (e.g. pytest)
• Knowledge of agile practices and able to perform in agile software development environments
• Strong knowledge of modern software development tools / ways of working (e.g. git/GitHub, DevOps tools for deployment) and should be able to show practice of commit early and deploy often

Preferred Qualifications

• Experience with Docker or containerised applications, especially architecture of multi‑container applications
• Knowledge of AI/ML approaches and deployment of AI/ML powered applications especially using language models or NLP and agent‑based approaches (e.g. LangGraph, PydanticAI, AutoGen)
• Knowledge of AI/ML evaluation and benchmarking approaches, experience with iterative improvement of AI/ML models and products
• Some experience with front‑end software development (e.g. React)

Closing Date for Applications: Monday 1st December 2025 (COB)
