Capital on Tap is an all-in-one business credit card and spend-management platform serving small and medium-sized businesses.
<div class="content-intro"><p><span style="font-family: verdana, geneva, sans-serif; font-size: 12pt;"><strong>We’re Capital on Tap 👋<br></strong></span><span style="font-family: verdana, geneva, sans-serif; font-size: 12pt;">💳 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.</span></p> <p><span style="font-family: verdana, geneva, sans-serif; font-size: 12pt;">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. </span></p> <p><span style="font-family: verdana, geneva, sans-serif; font-size: 12pt;">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! </span></p></div><p><span style="font-family: helvetica, arial, sans-serif;">🏡🏢This is a hybrid role, our engineering teams work from our London (Moorgate) Office 2 days per week.</span></p> <p><strong>The Role</strong></p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">We're looking for Senior Software Engineers to help us build the products that small businesses across the UK and US rely on every day.
