Company mission
Our mission is to change the world’s relationship with money.
Role
Who you are
- 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
- We’re on the hunt for a radically hands‑on Senior Web Developer - someone who doesn’t wait for permission, doesn’t need hand‑holding, and thrives pushing boundaries
- As this is an SE4 position, we’re looking for someone with strong industry experience of using 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
- Senior-level experience in web development - solid track record rebuilding or transforming websites with custom code
- Expert in front-end technologies, including (but not limited to) HTML5, CSS3 (animations and transitions), JavaScript (modern frameworks or vanilla)
- Figma master - you can interpret complex designs and turn them into fluid, working pages
- Independent, proactive mindset - you can take a concept and run with it; no micromanagement needed
- Comfortable with urgency - you understand deadlines, act with immediacy, and deliver without sacrificing quality
- Creative coder - you relish building playful, experimental, sci-fi‑themed interactions that stand out
Desirable
- Experience with canvas, WebGL, or three.js for 3D or immersive effects
- Prior work featuring motion design, scroll-triggered animations, or interactive storytelling
- Familiarity with performance optimization for dynamic media-rich pages
What the job involves
- Your mission: rebuild websites that are immersive, playful, and unapologetically futuristic. Think: add video, make text crawl around the video, imaginative interactions, all‑custom pages, immersive sci‑fi flair. No templates. No safe zones
- Rebuild and reimagine websites from the ground up - every page is custom-coded, unique, experimental
- Add multimedia experiences, like embedding video backgrounds and animating text that reacts to scroll or hover
- Build interactions that feel alive - interactive “immersive sci‑fi” components that spark curiosity
- Own your work - you understand urgency, deliver without prodding, and ship polished results fast
- Translate Figma designs into fully functioning experiences - pixel-perfect, responsive, and dynamic
- Iterate swiftly based on feedback - you're comfortable shipping often and refining as you go

Our take
People are increasingly not satisfied with the products being offered by traditional banks, which have proven slow to react to the needs of younger consumers who expect more from their everyday experiences.
Cleo was one of the first companies to make great use of chatbots that sit within Facebook's messenger app. This chatbot-first approach and Gen Z user base have given it strong virality. It now has millions of registered users, 99% of which are based in the US, leading to a decision to take a year break from the UK market to focus on its US Gen Z customers. And after a successful year in the US its now eyeing up a return to the UK.
Its Series C funding will help the company to double down in the US, where it will make a significant increase in employee headcount, and enable Cleo to maintain and expand its service during an economic downturn.
Financial advice delivered via bots is a crowded space, so Cleo benefits from having a strong brand presence. It has gone for very bold, fun, Gen Z-focused messaging which helps it to stand out from competitors such as Emma, Plum, and Chip.
