Senior Machine Learning Engineer

At MOTORS, we like to say that we know MOTORS!

Millions of people come to us every month to find their next car, because we keep the car search process simple. We have hundreds of thousands of used cars listed for sale by dealers nationwide, and guides, advice, tips and reviews to help buyers find the right one. We don't just help consumers, though.

For our dealer partners, we offer a unique advertising ecosystem that allows them to get their cars seen by buyers across some of the UK’s biggest car search sites: MOTORS, Cazoo, eBay, Gumtree and Parkers.

In 2024 we acquired Cazoo, one of the UK’s most recognised automotive brands, marking the start of an exciting new chapter. We’re now building on Cazoo’s strong brand recognition to create the next-generation car search experience—one that’s simpler, smarter, and more transparent.

We’re excited about what’s ahead, and we’re looking for ambitious, adaptable team members who thrive in a fast-moving, evolving business.
