Backend Software Developer Python or Java (Freelance possible)

Mission

To support the ongoing modernisation of its information systems, a public mobility organisation in Brussels is expanding its internal digital team. In this role, you contribute to the development and improvement of business applications within a secure and sustainable environment, working closely with the Solution Architect / Lead Developer and internal stakeholders.

You join a delivery team focused on business applications. You can independently deliver production-ready code in your day-to-day work. Strong command of Python or Java is required, with practical cloud knowledge, ideally in Azure, and a solid understanding of standard DevOps practices.

• Design, build and maintain application features, mainly on the backend, including APIs, services and data access.
• Work in a cloud environment, preferably Azure, covering configuration, logging, identity, storage and first-level troubleshooting of the services you use.
• Contribute to CI/CD pipelines, code reviews and automated testing.
• Apply good development practices, including secure secret handling and proper separation of dev, test and prod environments.
• Write clear, maintainable code and document delivered features.
• Estimate and refine work together with the Solution Architect / Lead Developer, and flag risks in time.
• Participate in agile ceremonies and collaborate in pair programming when needed.
• Develop and maintain REST APIs as part of the application landscape.

📝 Your profile

• You have 2 to 5 years of professional experience in software development. Internship experience alone is not sufficient.
• You are autonomous in day-to-day development work in at least one of these languages: Python or Java. Experience with both is an advantage.
• You have hands-on experience with public cloud services. Azure is preferred, including knowledge of resource groups, App Service, Functions, containers or equivalent services, identity, storage and monitoring at user level.
• You understand standard DevOps practices such as Git flow, pull requests, CI/CD, environment promotion and secret hygiene.
• You work comfortably with Git in a team-based development workflow.
• You are familiar with Agile ways of working.
• AZ-900 and/or AZ-204 certification is a plus, but relevant recent cloud experience remains more important than certification.
• You are curious, collaborative and able to work closely with a lead developer, not only execute assigned tickets.
• You use English for code, documentation and team communication. Dutch or French is an advantage.

Assets

• AZ-900, AZ-204, or another Azure developer or fundamentals certification.
• Docker.
• SQL, such as PostgreSQL, SQL Server or equivalent.
• Spring, FastAPI or Flask.
• Azure DevOps or GitHub Actions with practical experience beyond running a pipeline once.
