Looking to do work that matters?

We get it – it’s why most people come to Cleo. Together we’re fighting for the world’s financial health, building an AI that helps our users make the best money decisions from day one. We’ve helped 5 million people so far with personalised insights and a voice you don’t expect in FinTech. But it’s time to do more.

As we enter the next phase, we’re looking for more improvisers, data geeks and grown ups who want to own their work and create meaningful change.

The team 

You’ll join the existing data science function here at Cleo; a thoughtful and collaborative team of 10 dedicated data scientists, ML engineers, and analysts with significant industry experience that is at the heart of everything we do at Cleo. You’ll build and deploy production models that developers will feed directly into the product.

This position is essential in the expansion of both product and business. We are highly data driven, whether that be understanding natural language, deriving insights from financial data, or determining which financial product is best suited to a user. We have interesting problems to solve on an ever-increasing scale

UK App access: The Cleo app is no longer downloadable in the UK (but only until next year). If you’re an existing user, you’ll still have access to the app. But some features won’t be available (just for a little while). Why? 99% of our users are based in the US – where financial health is often overlooked. We’ve decided to shift our focus to where we can provide the most value and make the greatest impact for users who need it most. Then we’ll be able to apply what we learn to better support our UK users in the future. Check out this page for more information.
