Job description

Function

Our client is strengthening its digital capabilities to modernise internal information systems and support business operations through secure, sustainable business applications. This opportunity is for a medior software developer who will contribute to the delivery of backend-focused features within a collaborative team, working alongside a solution architect / lead developer and internal stakeholders.

Responsibilities

• Design, build, and maintain application features, with a strong focus on backend components such as APIs, services, and data access.
• Work within a cloud environment, preferably Azure, handling configuration, logging, identity, storage, and basic troubleshooting of the services in use.
• Contribute to CI/CD pipelines, code reviews, and automated testing practices.
• Follow good security and delivery habits, including not committing secrets and respecting dev / test / prod environments.
• Write clear, reviewed code and document your deliveries.
• Estimate and refine work together with the solution architect / lead developer, while flagging risks early.
• Participate in agile ceremonies and collaborate through pairing when tackling unfamiliar topics.

Profile

• 2 to 5 years of professional software development experience; internships alone are not sufficient.
• Confirmed in either Python or Java, with the ability to work independently on day-to-day tasks in at least one of the two.
• Practical experience with a public cloud environment, ideally Azure.
• Solid understanding of standard DevOps practices such as Git flow, pull requests, CI/CD, environment promotion, and secret management.
• Curious, proactive, and comfortable working closely with a technical lead rather than only executing tickets.
• Nice-to-have technical assets include Docker, SQL, Spring, FastAPI, Flask, Azure DevOps, or GitHub Actions.

Technical Skills

• Backend development with REST APIs and service-oriented application components.
• Python or Java as the primary programming language.
• Azure cloud services, ideally including resource groups, App Service / Functions / containers, identity, storage, and monitoring.
• CI/CD and version control with Git.
• Agile ways of working.
• Relevant certification such as AZ-900 or AZ-204 is a plus, but not required if cloud experience is solid and recent.

Practical Information

• On-site presence in Brussels is required at least three days per week.
• Language requirements: fluent English for code, documentation, and team communication; Dutch or French is a plus.
• This is a long-term consulting opportunity.
