------------------------------------------------------------------------------------------------------


🌏 Location: France, Germany, Spain, or Italy — full remote-friendly.

Join us as a Senior Backend Engineer to build the AI-powered tooling that enables Qonto's financial crime compliance teams to make decisions faster and with greater confidence, directly supporting our path to a full banking licence.

➡️ As a Backend Engineer at Qonto, you will

  • Build AI-integrated backend systems: Design and ship production-grade services that connect AI models (Claude, OpenAI, or open-source equivalents) to our compliance workflows, handling prompting, output parsing, and model behaviour in a real regulated-industry context
  • Own service architecture end-to-end: Co-own design, reliability, and scalability from day one, no PM layer between you and the technical decisions that shape the product
  • Automate AML/AFC compliance operations: Translate compliance agent workflows into software, from EDD automation to customer onboarding acceleration, with direct feedback from the ops teams you're helping
  • Drive continuous improvement: From production monitoring to post-mortems, you track impact, flag regressions, and improve what's in your scope with your peers and manager
  • Shape the technical direction: In a team of 5, every engineer carries architectural weight. You'll lead design discussions, anticipate risks, and contribute to how the platform evolves

➡️ What you can expect

  • Short time-boxes and lean process: daily goals, light Kanban, ceremonies, you spend most of your time building, not in planning meetings
  • AI is the product, not a side tool: this team's output is AI-powered compliance tooling. You'll use Claude or OpenAI to solve real problems, and you'll be expected to handle model behaviour reliably in production, not just use AI to go faster
  • Direct roadmap ownership: no dedicated PM means you and the team define priorities, your judgment shapes what gets built next
  • Close feedback loop: AML/AFC ops teams proactively raise needs and respond quickly to what you ship. Lead time reduction, prediction confidence, and agent throughput are the metrics that tell you it's working

➡️ Your future team

You'll join a team of 5 engineers within Qonto's Financial Crime Compliance (FCC) domain, alongside Ioannis (Tech Lead) and a mix of Senior/Staff Backend Engineers and Machine Learning Engineers.

You'll be part of a 190-strong backend engineering community within a 500+ Product Engineering department.

One important clarification: this team does not build fraud detection engines or KYC/KYB rule engines. Those exist elsewhere at Qonto. This team builds the automation layer on top, turning model outputs into decisions that help compliance agents respond faster. It's a backend role at the intersection of AI integration and regulated-industry operations.

➡️ About you

  • AI integration in production: You've shipped systems where AI (Claude, OpenAI, or open-source) is a core functional component, not a coding assistant, but the product itself.
  • Strong backend foundation: Solid experience with large-scale web application architecture and real production constraints + Ideally experience in Python.
  • Sound architectural judgment: You make confident system design decisions independently and can articulate the trade-offs.
  • Product instinct without a PM: You're comfortable owning the full cycle: scoping, prioritizing, shipping, success metrics 
At Qonto, we understand that true diversity isn’t just about ticking boxes on a hiring checklist. Apply regardless of the boxes you tick — who knows? You may have the missing piece of the puzzle we’ve been searching for all along.
