What you’ll be doing

We are looking for a frontend engineer with a passion for crafting beautiful, high-impact web experiences to join us on our mission to improve the world’s financial health. You’ll join a team of collaborative, creative, growth-minded people who care deeply about the users we serve.

• Work in a cross-functional team, collaborating with marketers, designers, data analysts and UX writers to grow our reach and improve the financial health of our users
• Build and ship high-impact web experiences using React and Next.js
• Create motion-led, visually engaging pages — animations, interactions and storytelling that bring our brand to life
• Own pages end-to-end — development, testing, optimisation and deployment, collaborating with designers, marketers and analysts to bring ideas to life
• Take full ownership of our website — stewarding the health of the repository, including its structure, CMS integrity and security posture
• Improve performance, SEO and how we build across our stack (Next.js, DatoCMS, Tailwind, Vercel)

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 and remote in the UK and 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.

Below are some specific skills and experience we are looking for:

• You have strong frontend skills (React, JavaScript — Next.js a plus)
• You care about craft — especially motion, polish and user experience
• You are comfortable owning work end-to-end, including deployment and performance
• You can collaborate and confidently work with creative and non-engineering teams

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 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 termly OKR planning cycles. You can view our public progression framework and salary bandings here: https://cleo-ai.progressionapp.com/
• 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 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;
• 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 and in-person
• We’ll pay for your OpenAI + Claude subscription
• 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.

The Cleo app is downloadable in the UK and USA. We’re not currently in the EU. We’ve shifted focus to where we can provide the most value for users who need it. We can share a slide deck detailing the app’s capabilities in more detail to help you through the interview process.
