Most back-end job ads could be swapped between companies without anyone noticing. So here's what's actually specific about this one.
We're Welcome to the Jungle. We build the Hiring Suite companies use to recruit: employer branding, job matching, sourcing and an ATS. Around 260 people between Paris and London, a product used by thousands of companies, and an engineering org that ships regularly rather than endless sprints.
You'd join a cross-functional squad alongside a Product Manager, a Designer and an Engineering Manager. Small team, real ownership, and a say in the technical decisions rather than a backlog handed to you.
Our main back-end stack is Elixir. You don't need to know it, several of our engineers learned it here, but you do need to be the kind of person who finds that interesting rather than inconvenient.
Design, build and maintain scalable back-end services, APIs and database schemas
Write clean, well-tested code, and review your teammates' code with actual feedback
Take part in architecture decisions rather than inherit them, and document what you decide
Work directly with your PM and Designer to clarify priorities and user needs, not just tickets
Debug production issues and fix the cause, not the symptom
Write unit and integration tests, pair when it helps, and keep test coverage honest with our QA team
Monitor performance, spot what's degrading, and do something about it
Follow security best practices and handle vulnerabilities when they come up
Handle support requests and bug fixes within agreed SLAs
Contribute to our CI/CD pipeline and to the overall developer experience
A 4-day work week with a fifth flexible one
Hybrid working
25 days of paid leave
Alan health insurance and Teale, our mental health support platform
Meal vouchers
Up to 75% reimbursement of your Navigo pass
Sick child leave

You'd rather unblock a teammate than finish your own ticket first.Clear communication in both French and English. Our engineering teams work across Paris and London.
