We are looking for a Solution Architect for the Future Proof Passenger Information (FPPI) program. As a Solution Architect, you will define solution architectures within the FPPI program.

• Act as a key partner between business stakeholders, IT managers, enterprise architects, domain architects, and delivery teams.
• Validate solution design and follow up on its implementation to ensure correct implementation of solution architecture.
• Share knowledge across colleagues.
• Evaluate project constraints to find alternatives, alleviate risks, and perform re-engineering if required.
• Update stakeholders about any issues connected to the architecture.
• Conduct architectural analysis of epics.

Conformity Criteria:

• Minimum 10 years of experience as a software architect (solution, integration, or application), demonstrated in the CV.
• Minimum 4 years of experience in the railway industry.
• Minimum 5 years of proven experience with API managers and API gateways.
• Minimum 5 years of proven experience in integration architecture.
• Certified for Archimate (minimum foundation level).
• Certified for Open Agile Architecture.
• Willing to work on-site up to 5 days per week in Brussels, if required.

Evaluation Criteria:

• Level of experience with Kafka, Azure Cloud, and event-driven architectures (number of projects, role, responsibilities).
• Experience in API design using Swagger/OpenAPI (number of APIs designed, role, complexity).
• Proficiency in UML and ArchiMate modeling (types of diagrams, use in projects, role).
• Depth and relevance of architectural experience in similar environments (scope, technologies, role, duration).
