Role Overview

Join us as a Backend Engineer to craft polished user experiences, highly scalable APIs and robust banking services, all to help create the finance solution all businesses love.

As a Backend Engineer, you will be part of a team of 180 highly skilled back‑end engineers from all over the world. You will work closely in cross‑functional teams to shape our finance solutions.

What you can expect: our methodology, the Qonto Way

• We highly value the analysis phase on software delivery. We’re putting a heavy emphasis on upfront technical designs, team reviews, and smart slicing. You can expect to focus on quality, which we believe drives the velocity our customers need.
• We think success comes from a space where you’re given time, support, and autonomy to improve yourself, our systems and our processes. Our lean toolbox enables you to monitor your constant improvements (Kaizen, PDCA) in a collaborative way with your peers and manager.
• Our engineers, working in cross‑functional teams, dedicate themselves to one feature at a time.
• We value the efficiency and productivity of our engineers: that’s why we provide each of our engineers with licenses for Cursor or Copilot, enabling them to focus on what they do best – coding innovative solutions.
