(Senior-Staff) Frontend Engineer in London

About Apron

Apron was started by a group of people who'd spent years building products for some of today's most successful global fintech companies. But there was one problem that no-one was solving: Business money. The kind that buys tomatoes, tiles, and till rolls. The kind that keeps suppliers happy and business booming. The kind that, before you know it, eats up your entire day. One million small businesses in the UK will each spend 5 hours this week paying and reconciling invoices, alongside countless hours chasing staff for expense receipts. This is a problem that's affecting entrepreneurs. Dreamers. Risk takers. Backbones of our communities. Imagine what they could do with this time instead. What would they build? How far could they go? That's why we created Apron as an essential tech layer 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 have grown fast over the past few years, expanding our team to circa 70 individuals across the UK and more. We are backed by Index Ventures, Bessemer Venture Partners, with participation of Visionaries Club and the founders of Melio and Klarna and we've raised $50m.

About The Team

Engineers at Apron are at the heart of what we do. Here’s what that means:

• We build with the customer in mind. We use top‐tier technology to build a product that genuinely makes their lives easier.
• We solve interesting puzzles. We tackle tricky problems and find new solutions.
• We embrace the complexity of finance. Working with money means navigating intricate business logic and thinking through every possible corner case. It’s a rewarding challenge where precision and attention to detail are crucial for building a trustworthy product.
• We write code we’re proud of. We work fast, but we build for the long term. Our code needs to be speedy, secure, and ready to grow with us. We integrate AI in our development workflow to enhance our capabilities.
• We own our work. We plan the approach, break it down, and bring it to life!
