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
- You’re excited by the opportunity to own and influence technical direction at a pillar level
- You’ve operated at senior/staff level across multiple teams or complex domains
- You bring strong technical judgment and think in long-term, scalable solutions
- You’re comfortable leading without authority and aligning teams around a shared direction
- You have a track record of building systems and practices used beyond your immediate team
- You enjoy mentoring and raising the bar for others
- You have strong, hands-on experience with Ruby on Rails (essential)
- You're based in Europe; we hire remotely across the EU and 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
What the job involves
- Acting as a Staff IC across a pillar, shaping technical direction and driving delivery across multiple squads
- Partnering with senior peers to define architecture and lead complex, high-impact initiatives
- Bringing teams together to ship ambitious product work that improves users’ financial health
- Building shared systems, patterns, and tooling that raise the bar across engineering
- Staying hands-on in our Ruby on Rails monolith — designing APIs, data models, and scalable services
- Anticipating risks and opportunities early, influencing plans and technical strategy
- Mentoring engineers and TLs, growing the next generation of technical leaders
- 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 Kubernetes. 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
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.
