Job description

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 opened our first Portuguese office in Porto in autumn 2025, and in less than a year it has grown to a team of 50. Lisbon is the next step. We're opening our first office in the city and looking for engineers to join as founding members of the team, helping shape how we build, hire and work here from day one.

The role starts out fully remote. Once our Lisbon office is open, it will move to a hybrid set-up of two days a week on site.

This is a multiple-headcount role, so please don't be put off if you've seen it advertised for a while.
