- Supporting colleagues through in‑hours support and optionally joining the compensated out‑of‑hours on‑call rotation.
- Contributing to cross‑cutting concerns that improve our engineering efforts.

About you:
You are passionate about making a positive difference in society by improving the financial health of our users. You align with our company values and engineering principles, which drive our ways of working and software delivery. As this is an SE3‑SE4 position, we’re looking for someone who has at least 4 years of industry experience using Ruby on Rails. You're based in the UK or Europe; we hire hybrid & remote in the UK & fully remotely across the EU. We love distributed teams. For this role, we’re ideally looking for candidates based within one hour either side of London time, to keep collaboration smooth and calendars sane.
Our Tech Stack:
Cleo is built as a Ruby on Rails monolith with a single React Native app front‑end, utilising TypeScript. We also leverage Python for machine learning services and PostgreSQL for our database, all hosted on AWS. Our CI/CD pipeline is fully automated, with production deployments happening on every merge via Kubernetes. Our backend engineers deploy multiple times a week, and we release our front‑end app to Google and Apple for review at least once a week. While we take a pragmatic approach, we place a strong emphasis on quality. Our code is peer‑reviewed, and we maintain automated testing using Minitest and CircleCI. We’re also actively working toward a more modular architecture, focusing on separating concerns to achieve all the benefits of microservices within a monolith, while progressively refactoring our code as we build new features. Everyone in the engineering team contributes to driving our technical strategy; voices and ideas from all levels are valued: we are all owners at Cleo.
What do you get for all your hard work?

- Flexibility. We can’t fight for the world’s financial health if we’re not healthy ourselves. We work with everyone to make sure they have the balance they need to do their best work.
- Work where you work best. We’re a globally distributed team. If you live in London we have a hybrid approach, we’d love you to spend one day a week or more in our beautiful office. If you’re outside London in the UK or EU, we’ll encourage you to spend a couple of days with us a few times per year. And we’ll cover your travel costs, naturally.
