Our primary languages are Go and Ruby for backend, EmberJS for frontend, and Kotlin and Swift for our mobile apps. Our platform runs on a Kubernetes cluster hosted on AWS, with PostgreSQL as our database of choice. We're also using Kafka for our event-driven architecture and ELK for logging and auditing, among many other tools, services, and applications.

What you can expect: our methodology, theQonto 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

Your future team

As a Backend Engineer at Qonto, you'll join one of our mission-based teams, typically made up of 5 to 10 engineers and led by a dedicated Engineering Manager.

You'll work alongside backend, web, iOS, and Android engineers, as well as Product Managers and Designers, joining either:

• A Product team, building and operating features used directly by customers.
• A Platform team, developing and maintaining the scalable foundations that help Product teams move faster.

Your team owns a clear mission end-to-end. You'll contribute to discovery, make technical decisions, build and release solutions, monitor production performance, and steadily raise quality standards, following our "you build it, you own it" approach.

Beyond your immediate team, you'll stay connected with Qonto's wider Backend community through our Backend Guild, where engineers share knowledge, shape technical standards, and improve developer experience across the organization.
