Data Engineer

About this role

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 | 🏢 2 days per week in office Data Engineering Team 🚀 The Data Platform team is responsible for designing, building, maintaining, and optimising our modern data platforms and infrastructure.

Our Values & Culture 🌞 Just Pilot: We never settle for "good enough". We pilot new ideas fast, ask questions to figure it out, and scale quickly. Why Not Today? Fast is as slow as we go - speed and simplicity gives us a competitive advantage. Be a Buddy: We tap in from day one to help the team, we do the right thing even if it's hard.
