Growth Marketing Engineer II - React (Web) | UK + EU (remote) Germany / remote in London

At Cleo, we're not just building another fintech app. We're embarking 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 rare success story: a profitable, fast-growing unicorn with over $300 million in ARR and growing over 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 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:

• 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.
• 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 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!
