- Implementing authentication mechanisms (OAuth 2.0, OpenID Connect, JWT) and ensuring security by design across all developments.
- Participating in DevOps and CI/CD processes, leveraging containerization and GitLab for streamlined delivery.
- Contributing to automated testing and continuous improvement of development practices.
- Adapting to evolving requirements and proactively identifying opportunities for innovation and optimization.
Technical Skills
- Confirmed expertise in PHP and JavaScript development
- Strong experience with API and REST web services
- Solid understanding of software architecture and design principles/patterns
- Authentication protocols: OAuth 2.0, OpenID Connect, JWT-based tokens
- Containerization technologies (e.g., Docker)
- DevOps, MLOps, and GitLab for CI/CD
- Application security and security by design
- SQL, NoSQL, and PostgreSQL databases
- Automated testing (junior level and above)
What We’re Looking For
- Builder mindset: proactive, ownership-driven, and passionate about delivering impact
- Proven problem-solving skills and a quality-oriented approach
- Autonomous, self-taught, and eager to stay ahead of technology trends
- Experience working in agile, innovative environments (Scrum, DevOps, CI/CD)
- Ability to collaborate effectively within multidisciplinary teams
- Rigor, attention to detail, and a commitment to excellence
Language Proficiency
- Fluency in French or Dutch is required
- Passive knowledge of the second language (French or Dutch) is expected
Other Requirements
- Start date: ASAP
- Project duration: Until 31/12/2026, with potential for renewal
- Full-time engagement (40 hours/week)
