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 not only at the top of their field but also 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, while growing alongside a company that’s scaling fast, this might be your perfect fit.

What You’ll Be Doing

• 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 our users’ financial health
• Working on our React Native application, building out amazing experiences for our users which bring financial health to life in the unique Cleo tone of voice.
• Writing automated tests alongside your code to give us the confidence to ship it
• 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 our 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 their ideas, so you can expect to be involved in product ideation sessions, user research calls, design reviews, retrospectives, ways of working sessions, product demos, OKR reviews.

Here Are 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 our 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 so we can experiment with the best pricing for different types of users.

Whichever squad and part of the business you land in, you will be shipping changes multiple times a week to our hundreds of thousands of active users and seeing 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 company 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 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.

• As this is an SE3/SE4 position, we’re looking for someone with strong industry experience of using React Native / React with TypeScript for a minimum of 5+ years. If it’s a less than that, maybe you want to look at our Product Engineer role.
• As your work will primarily involve working on features for our mobile apps, we’d either like to see some 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. Our backend engineers deploy multiple times a week, and we release our frontend 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 towards 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 & 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 termly OKR planning cycles.
• Work at one of the fastest-growing tech startups, backed by top VC firms, Balderton & EQT Ventures
• 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 of London, 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.
• Company-wide performance reviews every 4 months
• Generous pay increases for high-performing team members
• Equity top-ups awarded across all levels in performance reviews
• 25 days annual leave a year + public holidays (+ an additional day for every year you spend at Cleo, up to 30 days)
• 1 month paid sabbatical after 4 years at Cleo
• 6% employer-matched pension in the UK
• Private Medical Insurance via Vitality, dental cover, and life assurance
• Online mental health support via Spill
• Enhanced parental leave
• Workplace Nursery Scheme
• Paid for access to multiple AI platforms (ChatGPT, Codex, Claude)
• Access to the latest AI coding models

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. We can share a slide deck detailing the apps capabilities in more detail though, to help you through the interview process.
