You will work on a large-scale public-sector digitalisation initiative focused on building modular, interoperable case management platforms. These platforms support complex operational processes, integrate with multiple internal and external systems, and form part of a broader enterprise application landscape. The environment is functionally rich, technically layered, and long-term, requiring strong architectural oversight across application, data, integration, and infrastructure layers.

As a Solution Architect, you design and govern end-to-end technical solutions within a complex enterprise architecture. You ensure that solutions are coherent, scalable, and aligned across business, application, software, data, and infrastructure layers.

What you’ll do

  • You design solution architectures across multiple and complex knowledge domains within the enterprise architecture.
  • You define end-to-end technical solutions, ensuring consistency across application, information, software, and system layers.
  • You translate functional and business requirements into concrete architectural designs.
  • You ensure architectural coherence between new modules and the existing enterprise landscape.
  • You define and document architectural principles, decisions, and trade-offs.
  • You support development teams by providing architectural guidance throughout implementation.
  • You assess and validate proposed technical solutions, integrations, and deployment approaches.
  • You contribute to documentation, reporting, and architectural governance.
  • You explain architectural concepts clearly to both technical and non-technical stakeholders.

What are we looking for?

  • You have at least 10 years of experience in key IT project roles, including solution design and application implementation.
  • You have proven experience designing architectures across multiple layers (business, application, software, data, infrastructure).
  • You have experience defining end-to-end technical solutions and ensuring consistency across domains.
  • You have experience with complex implementation projects, preferably involving web applications, case management systems, or operational platforms.
  • You understand the full application development lifecycle and the roles involved.
  • You have solid knowledge of enterprise and solution architecture concepts.
  • You are familiar with cloud technologies (preferably Azure).
  • You have experience with CI/CD pipelines and modern delivery practices.
  • You have working knowledge of .NET-based environments.
  • You are familiar with enterprise integration patterns, microservices, containerisation, or BPMS concepts (strong asset).
  • You understand database concepts and terminology relevant to solution design.
  • You have sufficient infrastructure knowledge to design realistic, deployable solutions.
  • You have experience using EA Sparx or equivalent modelling tools.
  • You are open to leveraging AI-assisted tools in solution design and documentation.
  • You communicate fluently in English and Dutch OR French.
