## Description

Backend Developer (Java Spring Boot)

An in-house ERP system that powers the daily operations of several companies. From budget proposals to workforce planning and contract management, our platform helps streamline complex workflows that hundreds of people rely on every day.

Enter now an exciting new chapter: modernize our platform end-to-end. On the backend, we're migrating from Symfony/PHP to a scalable, service-oriented architecture in Java Spring Boot.

This is a big challenge-and a great opportunity for you to help shape the future of a mission-critical system that businesses and their people rely on every single day.

The Role

We're looking for a Backend Developer who loves solving real-world problems through clean, scalable, and maintainable code. You'll be joining a collaborative team where your contributions directly impact business-critical workflows and system architecture.

As a Backend Developer, you'll:

 * Lead the migration of core services from Symfony/PHP to Java Spring Boot.
 * Design and implement scalable, maintainable microservices.
 * Collaborate with frontend and product teams to deliver seamless, end-to-end features.
 * Ensure quality with robust testing practices (unit, integration, and end-to-end).
 * Contribute directly to the overall system architecture and long-term technical strategy.
 * Support and extend the existing Symfony backend as needed during the transition phase.
