Description

  • Ship a new AI agent roughly every 6 weeks, owning backend and AI logic from scoping through deployment.
  • Design and maintain reliable backend systems and pragmatic LLM guardrails that work in a regulated banking context.
  • Build user-facing AI agent features that scale as the AI Lab grows.
  • Use AI coding tools daily to speed up development, review, and delivery of features.
  • Contribute to frontend work in React/JavaScript when needed to unblock the squad.
  • Integrate backend work with Qonto’s core services and broader platform.
  • Collaborate with Product and Tech leadership to align delivery with the AI roadmap.
  • Own outcomes end to end within a small, autonomous squad with minimal process.

Requirements

  • Strong production experience in Python.
  • Working knowledge of Go or Ruby on Rails for integration with Qonto’s core services.
  • Experience shipping in a product-driven, user-centric environment.
  • Ability to work independently without relying on a tech lead.
  • Daily use of AI coding tools such as Cursor, Claude Code, or Copilot.
  • Genuine curiosity about AI and some hands-on experimentation or side projects.
  • Strong communication skills for explaining technical decisions to non-technical stakeholders.
  • Fintech or regulated-industry experience is a plus.
  • Frontend knowledge in React/JavaScript is a plus.
  • Production AI experience is not required; framework awareness with PydanticAI, LangGraph, or LangChain is appreciated.

Benefits

  • Unlimited access to AI tools including Claude Code, Cursor, Copilot, and Notion AI.
  • Python-first stack with hands-on AI agent work from day one.
  • Clear growth path toward an AI Software Engineer role.
  • Lean, autonomy-first culture with minimal process.
  • Opportunity to work closely with experienced AI Lab leadership and company founders.
