Full description
**We’re Capital on Tap 👋
**💳 Capital on Tap started because small businesses were underserved. Big banks were slow, their products weren't fit for purpose, and small business owners often couldn't access what they needed. We set out to fix that.
Today we're a financial platform - not just a credit card company. We offer a best-in-class business credit card, SME-focused spend management platform, a savings product that hit £1 billion in funds within its first year, and a growing suite of tools and financial products that make running a small business easier.
1,000+ employees, £20bn in annual card spend, 200,000+ customers, 17,000+ Trustpilot reviews averaging 4.7 stars, and we're profitable. We’ve done a pretty good job so far, but we’re just getting started!
📍 London / Porto | 🏢 2 days a week
The Team 🚀
You’ll join one of our platform teams (XP Platform, within Engineering). We build the foundations that every web and mobile app at Capital on Tap sits on: the design system and shared UI packages, the app shell, and core flows such as sign-in, settings and protected actions. Product teams build their features on top of this, so we set the patterns, prove they work, and help other teams adopt them.
Right now the focus is the Customer Portal, the signed-in experience our customers use every day. We work very closely with Design, talk to Product early about what’s coming, and partner with the Engineering Architecture Team on where the frontend is heading. We also run a monthly demo for the whole department to share what we’ve built.
The Role
This role is for an engineer who wants to make web development the focus of their career. You might be a backend or mobile engineer who has picked up some React along the way, or someone who has built a few things in their own time and wants to do it properly. You don’t need to be an expert yet. What matters is real interest in the web and the drive to get good at it.
You’ll join a team of experienced web and mobile engineers and learn the craft on real work, not side projects. You’ll pair with seniors, have your code reviewed by people who care about it, and over time take full ownership of features in packages that the rest of the department builds on. Because those packages are used by other engineers, you’ll learn to think about developer experience as well as what the customer sees.
You already know how Capital on Tap works, which products we have and how our teams fit together. That context is useful here from day one.
What You’ll Be Doing
- Build and maintain components, features and shared packages in React and TypeScript, with support from senior engineers
- Work with Design to bring our design system to life in code, so customers get a consistent experience across the product
