Senior Software Engineer | Backend in City of London

About Apron

Apron was started by a group of people who’d spent years building products for a number of global fintech companies. But there was one problem that no-one was solving: business payments. The kind that buy tomatoes, tiles, and till rolls. The kind that keep suppliers happy and business booming. The kind that, before you know it, eat up your entire day. One million small businesses in the UK will spend 5 hours this week paying and reconciling invoices. Collectively, that's over 500 years. And this is a problem that’s affecting entrepreneurs, dreamers, risk takers, and the backbones of our communities. Imagine what they could do with this time instead. What would they build? What would they create? That’s why we created Apron as a critical cog in the small business machine. We flip the payment experience from blocking business to boosting it. Apron weaves neatly into your workflow and tightens it up, turning hours into minutes.

We are backed by Index Ventures, Bessemer Venture Partners, with participation from Visionaries Club and the founders of Melio and Klarna.
