Head of Data Science

The team at MRJ Recruitment are partnering with a fast-scaling, innovation-led business making significant investment across Data Science, AI and intelligent automation, with a clear mission to turn data into a core commercial growth engine.

This is a rare opportunity for an ambitious Data Science leader to build and shape a function with genuine executive backing, modern infrastructure and the freedom to define strategy, architecture and capability from the ground up.

The business is entering a major phase, focused on creating intelligent systems that connect raw data with live commercial outcomes, spanning product intelligence, pricing optimisation, recommendation engines, automated creative generation and next-generation search experiences.

As the Head of Data Science, you’ll lead the evolution of advanced ML capabilities across the organisation, driving automation, experimentation and real-time decision-making at scale.

You’ll operate at the intersection of commercial strategy, machine learning and innovation, building systems that reduce manual intervention, improve performance and unlock entirely new revenue opportunities.

This is not a role focused on maintaining legacy models or managing incremental change. You’ll define the vision, influence senior stakeholders, grow a high-performing Data Science capability and help establish data as a true competitive advantage for the business.
