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

Join us as a Web Engineer Intern in the Activation team and help newly activated customers get real value from Qonto. You’ll ship small, well-scoped web features in React that help customers top up their account, discover our products and get started with confidence.

What you’ll do

  • Ship real features: pick up well-scoped React tickets, from UI changes to broader features as your skills grow.
  • Work across disciplines: clarify requirements with product, design, web, backend and mobile engineers, and take part in task breakdown and estimation.
  • Learn our engineering workflow: open pull requests, iterate through code review and merge safely.
  • Own quality, with support: run engineer QA, fix issues and follow your features through release and post-release checks.
  • Help us improve: when priorities allow, explore monitoring (Sentry, Grafana), small refactors and AI-assisted ways of working.

What we’re looking for

  • You have web foundations: HTML, CSS, JavaScript and React. School and personal projects count.
  • You know the basics of Git: you can explain branching, pull requests and review.
  • You communicate proactively: you ask questions early, flag blockers and welcome feedback.
  • You are studying computer science or a related technical field, ideally Master 2 or an engineering degree. A strong Master 1 profile can also be considered.
  • You work comfortably in English and you’re willing to use AI while understanding, challenging and verifying what it produces

What we can offer you

  • Visible impact: your work reaches real customers.
  • The full feature lifecycle: requirements, build, QA, release and follow-up, not an isolated school exercise.
  • Hands-on mentoring from experienced web engineers, with Susana Prado López as your mentor.
  • Progressive responsibility: start with small tickets and widen your scope as you learn the codebase.
  • Fintech and AI exposure, in a team spanning web, backend, iOS and Android.

Your future manager: Your manager will be Benjamin Director of Engineering.His background? Benjamin started as a network software developer at Thales, where he also owned software integration and verification for defence routing protocols. He then moved into machine learning and became CTO of Collective Thinking, a healthcare deep-learning startup, where he hired, onboarded and managed a team of 10 engineers. He joined Qonto in 2021 as Lead Backend, became Senior Lead Backend, then Head of Back-End, and is now Director of Engineering.

Practical details

  • Internship starting January 2027
  • Hybrid, based in Berlin, Paris OR Barcelona
  • You’ll work on day-to-day product development, not a dedicated thesis project, so check that it fits your school’s requirements.
