Lead Product Data Scientist in Hounslow

A career without limits. As the nation’s flag carrier, we take great pride in connecting Britain with the world and the world with Britain. It’s something we’ve been doing for over 100 years, ever since we launched the world’s first international scheduled air service between London and Paris. This originality has been in our blood since day one. It’s the spirit we share with the people that fly with us, our partners, and our colleagues.

The role of Lead Product Data Scientist involves leading a full-stack data science and software engineering product squad to deliver optimisation and machine-learning decision-support products for an operational business area, aligned to the integrated operations vision. This is a hands-on leadership role where you will own the end-to-end product lifecycle from discovery and scoping through to architecture, delivery, testing, adoption, value capture and ongoing support.

What you’ll do:

• Lead the end-to-end product development process for machine learning and optimisation products, from discovery to live operation and support.
• Understand business problems and end-to-end processes to identify opportunities to improve decisions using decision-support tooling.
• Design modelling approaches and software architecture that are scalable, maintainable and aligned to the integrated operations vision.
• Create delivery timelines and feature roadmaps prioritised by business value, managing internal and external dependencies.
• Communicate product vision and secure alignment with senior stakeholders and business users.
• Ensure timely delivery of features, modules and the overall codebase across a cross-functional squad.
• Define testing and validation approaches for individual features and end-to-end systems, with a focus on robustness and value capture.
• Lead regular internal and stakeholder sessions to drive modelling decisions and delivery predictability.
• Lead change management including communications, training and engagement to ensure adoption and realised value.
• Own product management including user experience and front-end design considerations.
• Provide product support including bug fixing and coordination with dependent teams.
• Embed effective agile ways of working including version control, code reviews, documentation and continuous improvement.

What you’ll bring to British Airways:

• Strong hands-on experience applying machine learning and optimisation techniques to real-world problems.
• Deep technical fluency in Python and practical experience using data science, ML and optimisation tooling.
• Experience delivering production-quality systems with robust logging and testing.
• Confidence leading and guiding a full-stack squad across modelling, software engineering and delivery discipline.
• Ability to communicate complex technical concepts clearly to a wide range of audiences.
• Pragmatic, outcome-focused mindset with a strong bias for delivery and business impact.

Your experience:

• Master’s degree or equivalent experience in data science, machine learning or operational research.
• Several years’ experience building or leading production machine learning or optimisation products at scale.
• Experience developing industrialised software, particularly data-science-led products.
• Experience in operational, transport, airline or network-based domains is advantageous.
