Engineer II - React/React Native | UK + EU (remote)

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. Cleo is a profitable, fast‑growing unicorn with over $300 million in ARR and growing at more than 2x year‑over‑year. This isn't just a job; it's a chance to join a team of brilliant, driven individuals who are passionate about making a real difference. We have an exceptionally high bar for talent, seeking individuals who are at the top of their field and who embody our culture of collaboration and positive impact. If you’re driven by complex challenges that push your expertise, the chance to shape something truly transformative, and the potential to share in Cleo’s success as we scale, this might be your perfect fit.

What you’ll be doing

• We’re looking for a brilliant Frontend React/React Native engineer with an eye for UI/UX design to join us on our mission to fight for the world’s financial health.
• You’ll join a team of adaptable, creative, and product‑focused engineers who ship working software.
• Joining a cross‑functional product squad with a mix of frontend engineers, designers, UX writers, backend engineers, data analysts, and others to develop features that improve users’ financial health.
• Working on our React Native application, building out amazing experiences for our users that bring financial health to life in the unique Cleo tone of voice.
• Writing automated tests alongside your code to give us confidence to ship.
• Using AB‑tests, feature flags, and other tools that let us iterate quickly.
• Using data to dig into user journeys, detecting problems, and helping to optimise the Cleo experience.
• Being part of the rota for weekly app releases to the Apple and Google app stores.
• Getting involved in cross‑cutting concerns that lift our entire engineering effort with the rest of the frontend chapter.
• Taking part in shaping all the work your squad does, not just the technical parts.
• Delivery is a team sport, and we encourage everyone at Cleo to share ideas.
• You can expect involvement in product ideation sessions, user research calls, design reviews, retrospectives, ways of working sessions, product demos, and OKR reviews.

Some examples, big and small, of the kinds of product feature work our engineers have taken part in over the last year:

• Building a secured credit card from scratch to help users improve their credit scores without changing their habits.
• Launching our new budget rewind feature to help users understand their pay‑cycle and provide them with better analysis of how they got on with their budget.
• Adding discount plans and tiering options to our subscriptions to experiment with the best pricing for different users.

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

About you

• You are passionate about making a positive difference in society by improving the financial health of our users.
• You align with our values and engineering principles, which drive our ways of working and software delivery.
• You’re based in the UK or Europe; we hire hybrid & remote in the UK & fully remote across the EU.
• For this frontend‑focused role, we also have some specific asks:
• Strengthening industry experience of using React Native / React with TypeScript for a minimum of 2+ years.
• If it’s a lot more than that, maybe consider our Senior role.
• As your work will primarily involve features for our mobile apps, we’d like to see proven experience in this area or a genuine passion for moving into the mobile app space.

Our Tech Stack

Cleo is built as a Ruby on Rails monolith with a single React Native app frontend, 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 Heroku. Backend engineers deploy multiple times a week, and we release our frontend app to Google and Apple for review at least once a week. We take a pragmatic approach and place a strong emphasis on quality. Our code is peer‑reviewed, and we maintain automated testing using Minitest and CircleCI. We're actively working toward a more modular architecture, focusing on separating concerns to achieve 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?

• A competitive compensation package (base + equity) with 3 annual reviews, aligned to our quarterly OKR planning cycles.
• A clear progression plan. We want you to keep growing. That means trying new things, leading others, challenging the status quo and owning your impact—always with our complete support.
• 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.
• Other benefits include company‑wide performance reviews every 4 months, generous pay increases for high‑performing team members, equity top‑ups for team members getting promoted, an additional day for every year you spend at Cleo (up to 30 days), 1 month paid sabbatical after 4 years at Cleo, regular socials and activities, online mental health support via Spill, and many more, depending on your location!

We strongly encourage applications from people of colour, the LGBTQ+ community, people with disabilities, neurodivergent people, parents, carers, and people from lower socio‑economic backgrounds. If there’s anything we can do to accommodate your specific situation, please let us know.

App access: The Cleo app is downloadable in the UK & USA. We’re not currently in the EU. 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.
