About Cleo

At Cleo, we’re not just building another fintech app. We’re on a mission to fundamentally change humanity’s relationship with money. Imagine a world where everyone, regardless of background or income, has access to a hyper‑intelligent financial advisor in their pocket. That’s the future we’re creating.

About the Company

Cleo is a profitable, fast‑growing unicorn with over $300 million in ARR and growing at more than 2× year‑over‑year. We have a high bar for talent and a culture of collaboration and positive impact. We’re looking for people who thrive on complex challenges and want to shape something truly transformative.

What You’ll Be Doing

• Join a cross‑functional product squad—frontend engineers, designers, UX writers, backend engineers, data analysts—to develop features that improve our users’ financial health.
• Work on our React Native application, building amazing experiences in Cleo’s distinct tone of voice.
• Write automated tests alongside your code to give us confidence to ship.
• Use AB‑Tests, feature flags and other tools to iterate quickly.

• Participate in the rota for our weekly app releases to Apple and Google app stores.
• Contribute to cross‑cutting concerns that lift our entire engineering effort.

Examples of recent product work include:

• Building a secured credit card from scratch to help users improve credit scores.
• Launching a budget rewind feature that helps users understand their pay‑cycle.

Whichever squad you land in, you will ship changes multiple times a week to hundreds of thousands of active users and see your work impacting the financial health of those most in need.
