Senior Software Engineer

Were Capital on Tap
Capital on Tap started because small businesses were underserved. Big banks were slow their products werent fit for purpose and small business owners often couldnt access what they needed. We set out to fix that.

Today were 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.

1000 employees 20bn in annual card spend 200000 customers 17000 Trustpilot reviews averaging 4.7 stars and were profitable. Weve done a pretty good job so far but were just getting started!
