Our journey: Founded by Alexandre and Steve in July 2017, Qonto has rapidly gained trust, serving over 600,000 customers. Thanks to our team of 1,600+ Qontoers, we also made it to the LinkedIn Top Companies French ranking!

Role

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

As a Backend Engineer, you will be part of a team of 180 back-end engineers from around the world. You will work in cross-functional teams to shape our finance solutions, contribute to the direction of our banking product, manage growing user-base needs, and deliver high-quality products in a fast-paced environment.

Your responsibilities

• Design, develop, deploy and maintain new and existing applications to reach the team’s goals and meet stakeholders’ needs
• Produce and ship high-quality, well-documented code
• Co-own our services architecture, resilience, scalability and robustness, with respect to Domain-Driven Design principles

Technology & team

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

What you can expect: our methodology, the Qonto Way — emphasis on upfront technical designs, team reviews, and smart slicing to focus on quality and velocity.

We value time, support, and autonomy to improve yourself and our systems, with a lean toolbox to monitor improvements (Kaizen, PDCA) in a collaborative way.

Engineers work in cross-functional teams, dedicating themselves to one feature at a time and benefiting from licenses for Cursor or Copilot to accelerate coding innovative solutions.
