ABOUT THE ROLE

As a Full-Stack Java Developer, you'll join our team and continue the development of a management platform from its current prototype stage into a production-grade enterprise product.

• Evolve the database schema and ORM layer (Hibernate ORM with Panache) for PostgreSQL, ensuring data integrity and performance
• Implement and maintain the contract submission state machine workflow
• Extend the role-based access control (RBAC) system with fine-grained permissions across users, organizations, and roles
• Build and maintain containerized deployments using Podman for both development and production environments
• Integrate PDF generation (HTML-to-PDF rendering) and OCR features for processing scanned contract documents
• Write and maintain unit and integration tests (JUnit 5, REST-Assured)
• Participate in requirements analysis and translate use cases and state machine designs into working software
• Maintain and improve project documentation
• Collaborate with infrastructure and operations teams on deployment, tunneling, and remote access configurations

• Internationalization (i18n) – Implementing and maintaining bilingual (English/French) UIs

Database

• PostgreSQL – Schema design, SQL queries, JDBC configuration, and administration
• MariaDB / MySQL – Secondary database support and compatibility awareness
