A federal public service in Belgium's Brussels-Capital Region is modernising the application landscape behind unemployment regulation, including eligibility, payments, debt management, and financial and accounting processing. As a technical functional analyst, you will connect business requirements with Java, Spring, microservices, and secure data integration across legacy, cloud, and hybrid components.
The mission
The portfolio combines long-running applications with modern architectures being introduced to reduce technical debt and support cloud adoption. These systems underpin critical public services, so functional decisions must remain consistent across applications, data flows, security controls, and operational processes. NIS2 requirements are translated into architecture, secure coding, monitoring, and auditability practices.
Your day-to-day scope covers functional analysis with a technical focus, data modelling, integration design, and guidance to development teams. You will assess performance and scalability, review Java and Spring solutions, and help teams apply API-driven and event-driven architecture patterns. You will also coordinate discussions between business, development, security, and infrastructure stakeholders, documenting decisions and supporting maintainable designs across the application landscape.
Your responsibilities
- Translate business needs into clear functional and technical designs for applications supporting unemployment regulation.
- Design and assess data models, integrations, and secure APIs using relational databases, MySQL, API-driven architecture, and event-driven architecture.
- Guide Java and Spring development teams through design reviews, architectural decisions, and proof-of-concepts.
- Improve the maintainability, security, performance, and scalability of legacy and modern components by reducing unnecessary coupling.
- Embed security by design and translate NIS2 requirements into secure coding, monitoring, and auditability measures.
- Align business, development, security, and infrastructure stakeholders, using Atlassian/Jira and clear documentation to track decisions and actions.
