About the role

We are growing our ML team to support new projects and product developments. We are looking for AI builders; you will be working on developing and deploying AI systems to solve complex problems that have real-world impact.

You’ll join an existing ML team that works in close collaboration with software, hardware and systems teams to get useful AI into the hands of users. Our ML team works end-to-end, from R&D to deployment, across traditional ML, deep learning, data engineering and LLM/agentic systems.

As a Senior ML Engineer, you will be responsible for leading development effort on projects and products. You will design end-to-end solutions from early concepts to deployment, owning the quality of the software and ML solution. As a senior you will be expected to mentor colleagues in the team, maintain coding standards and act as a role-model for good ML, data, and software practices and advocate for this in your work around the business.

No prior defence experience is required. We’re interested in people who’ve built and deployed AI systems in demanding environments and are passionate about delivering tangible value to end users, whatever the sector.
