Our experts push the boundaries of open source every day to build a smarter, more efficient, and more responsible digital world. Here, we don't just follow trends, we create them!

We are currently looking for an experienced Freelance Java Developer to join us in Brussels and take part in large-scale, impactful digital projects for one of our premium clients.

Position Overview

Status: Freelance (Independent / Prestation de services)
Location: Brussels, Belgium (Hybrid model: 2-3 days remote per week)
Seniority Level: Medior (3+ years) to Senior (10+ years)
Languages: Professional proficiency in either Dutch or French OR English

Your Mission & Responsibilities

As a Freelance Java Developer, you will be integrated into a dynamic environment to design, develop, and maintain robust enterprise applications. Your main responsibilities will include:

Designing and implementing high-quality software solutions using Java / Java EE technologies.
Implementing and managing API and Web Services standards (OAuth2, OpenAPI, SOAP) and working within SOA / REST models.
Translating business requirements into technical designs utilizing UML and BPMN.
Collaborating within an Agile/Scrum methodology, while aligning with corporate governance frameworks (ITIL, PMBOK/PRINCE2).
Contributing to architectural discussions and evolution using modern architecture frameworks (TOGAF, Archi, Sparx).
Ensuring code quality, version control, and seamless integration using GIT and client frameworks (Axis 2, CXF, .Net compatibility).

Your Profile

Experience: You have at least 3 years (Medior) to 10+ years (Senior) of proven experience in backend Java development.
Core Tech Stack: Deep expertise in Java/Java EE, REST/SOA architectures, API security (OAuth2), and SOAP/OpenAPI standards.
Methodologies: Strong familiarity with Agile/Scrum environments. Knowledge of ITIL, Prince2, or TOGAF is a major asset.
Tools: Proficiency with GIT, UML/BPMN modeling tools (Sparx, Archi), and integration frameworks (Axis 2, CXF).
Soft Skills: Autonomous, proactive, team-oriented, and solution-driven.

Vibrant Culture: Your year will be animated by group and agency events: annual convention, participation in trade fairs, summer party, and both formal & informal afterworks.

The Next Steps

First contact: A phone call to discuss your aspirations, availability, and what we can offer you.
Meeting: An opportunity to get to know each other and explore your professional background.
Business interview: A deep-dive discussion with one of our experts to assess your technical skills and define your goals.
