<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.

We're looking for engineers who understand the problem, challenge the approach when it needs it, and take pride in the quality of what they ship. We only build what the customer wants.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><br><span style="font-family: helvetica, arial, sans-serif;"><strong>What You’ll Be Doing</strong> </span></p> <ul> <li class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><span style="font-family: helvetica, arial, sans-serif;">Designing and building robust, scalable solutions in .Net/C#, taking full ownership of the SDLC from concept through to production</span></li> <li class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><span style="font-family: helvetica, arial, sans-serif;">Playing an active role in architectural decisions and technical direction, shaping how things are built, not just building them</span></li> <li class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><span style="font-family: helvetica, arial, sans-serif;">Working closely with Product and QA, bringing your technical perspective early and often</span></li> <li class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><span style="font-family: helvetica, arial, sans-serif;">Writing bulletproof unit and integration tests and holding a high bar for code quality across the team</span></li> <li class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><span style="font-family: helvetica, arial, sans-serif;">Communicating clearly across technical and non-technical stakeholders, translat
