Capital on Tap
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!
🏡🏢This is a Hybrid role, the Engineering team work from our London (Moorgate) Offices 2 days per week.
This is a multiple headcount role, so please don’t be put off if you’ve seen this advertised for a while.

- Collaborate closely with Product, QA, and Team Leads to align technical execution with business goals
- Identify and mitigate technical risk proactively, keeping delivery on track
- Champion engineering best practices, including adoption of AI tools and automation
We’re Looking For 🔎
- Extensive commercial experience with C# and.NET, capable of writing clean, well-tested, production-grade code
- Strong experience designing and building microservices and distributed systems
- Solid grounding in RESTful API design and Azure cloud development
- Deep familiarity with modern software development practices and scalable system architecture
- Experience working cross-functionally with Product, QA, and other stakeholders
- Pragmatic approach to delivery; you know how to ship an MVP and iterate with purpose
- Ability to embed deeply within an engineering group, building strong domain knowledge over time and becoming a trusted technical voice across the team and wider business
