Summary and responsibilities

Role overview

Summary

Join Qonto as a Senior/Staff Go Backend Engineer to build and maintain the financial infrastructure for over 750,000 European SMEs. This role involves designing, building, deploying, and owning highly scalable APIs and robust banking services, ensuring reliability and performance for real-time financial transactions.

[OUR MISSION AND CUSTOMERS] We are creating the freedom for SMEs to succeed by delivering Europe's leading finance workspace with banking at its core, augmented by financial tools. We are proud to be rated 4.7 on Trustpilot, based on 60,000 reviews. Our culture puts customer satisfaction at the core of what we do.

[OUR JOURNEY] Founded in 2016 and launched in 2017 by Alexandre and Steve, Qonto has grown to 1,700 Qontoers serving over 750,000 customers across 8 European countries. We have been profitable since 2023, and we are just getting started.

[OUR BELIEFS] We hire for skills and potential. With 80+ nationalities, 45% women, and 56% of women in our leadership team, diversity isn't a program; It's who we are. We've built a discrimination-free hiring process because the best teams are built on merit.

[AI AT QONTO] AI is deeply embedded in how we work - Every Qontoer gets unlimited access to the best AI tools. We want people who experiment without waiting for permission, push AI beyond the obvious, know when to trust it, and when to question it.

Location: You can choose to work in Qonto as long as you're living in (or willing to relocate to) either Germany, France, Italy, Serbia, or Spain.

Join us as Senior Backend Engineer to build the financial infrastructure that 750,000+ European SMEs depend on every day, from highly scalable APIs to robust banking services that handle real money, in real time, with zero room for mistakes.

You will join one of our mission-based teams of 5 to 10 engineers, led by a dedicated Engineering Manager. You will work alongside backend, web, iOS, and Android engineers, as well as Product Managers and Designers, in either a Product team (building features used directly by customers) or a Platform team (developing the scalable foundations that help Product teams move faster). Your team owns a clear mission end-to-end, following our "you build it, you own it" approach, and you will stay connected to the wider Backend community through our Backend Guild.

➡️ What you'll do

  • Design, build, deploy, and maintain services handling real financial transactions, owning reliability in production, not just at merge time

  • Co-own service architecture, resilience, and scalability with respect to Domain-Driven Design principles

  • Grow in technical leadership: lead design discussions, anticipate risks, and mentor less experienced engineers

  • Drive continuous improvement, from fixing flaky CI to running post-mortems and propagating learnings across the team

  • Contribute to discovery, make technical decisions, monitor production performance, and steadily raise quality standards

➡️ What we're looking for

  • Technical expertise: Strong backend engineering experience with exposure to large-scale web application architecture and real production constraints

  • Stack fluency: You don't need to know our exact stack, but you transfer fast and are comfortable with similar technologies

  • Quality-driven: You write tests, set up monitoring, handle incidents methodically, and do root cause analysis

  • Ownership mindset: You track impact after release, flag regressions, and improve what's in your scope without being asked

  • Team player: You are comfortable working in squad teams with PMs, Designers, and other stacks, and you are fluent in English

➡️ What we can offer you

  • Our methodology, the Qonto Way: We value upfront technical design, team reviews, and smart slicing. Quality drives the velocity our customers need

  • Autonomy: Our org assigns one team lead per project across stacks, giving your team a clear mission and full autonomy on how it operates

  • Continuous improvement: Our lean toolbox, Kaizen, PDCA, lets you monitor and drive improvement collaboratively with your peers and manager

  • AI tooling: Each engineer gets access to Cursor or Copilot, and we want people who use AI to raise the bar, not just to go faster

  • Our stack: Go and Ruby are our primary languages. Our platform runs on a Kubernetes cluster hosted on AWS, with PostgreSQL as our database of choice. We also use Kafka for event-driven architecture and ELK for logging and auditing, among many other tools and services
