Fullstack Engineer, Growth

  • Permanent contract 
  • Paris


At Upflow, we’re building the platform revolutionizing how B2B businesses get paid.

Today, most companies are still struggling to collect payments from their customers: hundreds of unpaid invoices, anarchic communications, multiple payment methods. They lose tons of hours on zero value-added tasks, suffer from late payments that hinder their growth, and sometimes simply go bust because of cash flow issues. It’s time for a change.

Upflow is the modern hub to manage all data exchanges, communications, and payments to get paid faster, simpler. We are a product-led organization solving this problem with a tech approach.

We’ve launched in 2018 and are trusted by hundreds of awesome users in the EU & US including Lattice, Front, Triplebyte, Iziwork, Adikteev, Proxyclick, and more. We’re also backed by leading investors (YCombinator, 9yards, eFounders) and top executives business angels from N26, Square, Mercury, Uber, and Netsuite.

We’re a remote-friendly, distributed team across 3 continents and rapidly expanding. Our primary focus is to support our fast growth in the US. Now’s a perfect time to join if you’re looking for an exciting international experience.

Job description

About Upflow

Getting paid on time represents a significant problem for B2B companies. Unlike consumer payments, where we’ve seen massive amounts of innovation in the form of companies like Venmo & Revolut, B2B payments remain archaic, with most of the work being done in spreadsheets and involving significant amounts of back and forth between different stakeholders.

These inefficiencies are extremely problematic for companies, so much so that some go bankrupt because of this - and COVID hasn’t helped! We’re on a mission to fix this, and bring delightful B2C experiences to B2B finance teams in the process.

We launched in 2018 and today are trusted by hundreds of amazing users across the EU & US including Lattice, Front, Triplebyte, Iziwork, Adikteev, Proxyclick and more. We’re also backed by leading investors (YCombinator, 9yards, eFounders) and top BAs from N26, Square, Mercury, Uber and Netsuite.
