Backend Developer - PHP Symfony

Job description

There are those who piece together scripts they found left and right, and there are those who really dive into purposeful code. You want to be part of the second category: those who design the code of tomorrow’s applications!


You believe there’s no point in rushing. Using the latest, quickest framework or language isn't the solution to everything. Real, robust code requires a lot of thinking and testing, and it should be easy to update without risks!

We use PHP, Symfony, PostgreSQL, Algolia, and other tools to develop services via REST APIs. Each piece of code is carefully built and tested and reviewed with love by another developer.

We also use the Clean Architecture, TDD, clean code principles, boyscout rule and so on.





Reports to the CTO




  • Propose new ideas to improve and iterate on our product
  • Assess the impact of your ideas
  • Evaluate development workloads
  • Design development architecture
  • Follow a process of TDD (Test Driven Development)
  • Review and comment on your teammates' pull requests




  • Impeccable writing skills (which will be tested), in French and English
  • Interest in applications architecture (including concepts like design patterns, clean architecture, and more)
  • Experience with REST APIs
  • Familiarity with technologies such as PHP, Symfony, Twig, PostgreSQL, PHPUnit, Git, Composer, or others
  • Familiarity with continuous deployment and integration
  • A love of learning
  • Reliability and kindness


  • 4 years’ experience as back end developer




  • The journey starts with a phone interview with our Engineering Manager.

Then we plan several face to face meetings:

  • A technical assessment with some of the Tech team members
  • An HR meeting combined to a « cultural fit » meeting with member from various teams (Student Success, Revenues, Marketing…) to help you to better understand the kind of people you will work with
  • A meeting with Romain, our CTO: you will have the opportunity to understand his vision and ask all the remaining questions you could have

You will also be asked to provide us with professional references contact detail.
