Senior Software Engineer (Backend) About ApronApron is building something game-changing.Founded in 2021, Apron set out to help SMBs win. Small businesses are the backbone of the economy, yet the systems they rely on (particularly around payments) are slow, manual and not built for them. The biggest threat to small business is cash flow, often stemming from a gap between the demand payments put on owners and the aptitude to make the payments effectively.Apron changes that. We are closing the gap by digitising and simplifying the payments process: capturing invoices, issuing expense cards, paying and getting paid, all in one place.We have grown fast over the past few years, expanding our team to circa 100 individuals across the UK, Germany, Spain and more. We are backed by Index Ventures, Bessemer Venture Partners, Zinal Grow and Tony Fadell and we’ve raised $50m.The ambition from here is not incremental growth. Apron is building a category-defining, global fintech business with a clear path to significant revenue scale and international expansion.
