Introductie
We are looking for a rigorous and analytical Functional Analyst to join a team responsible for business-critical, real-time operational software.
Organisatie
As part of initiatives related to regulatory compliance and data exchange with external market actors, you will play a central role in the implementation and configuration of inbound and outbound data flows between internal systems and external organisations.
You will bridge the gap between business requirements, functional specifications and the technical realities of systems integration.
Functie
The Role
This is specifically a Functional Analysis role, distinct from Business Analysis. Business requirements are provided by Business Analysts, after which you translate them into specifications that development teams can build and testers can verify.
This includes defining system behaviour, interfaces, data, edge cases and failure scenarios that may not yet be covered by the initial business requirements.
Responsibilities
• Review incoming business and user requirements for completeness, consistency andfeasibility.
• Identify ambiguities, contradictions and unstated assumptions.
• Translate requirements into detailed functional specifications, including features,user stories, acceptance criteria, business rules, system behaviour and error handling.
• Specify system-to-system integrations and define exchanged data, failure scenarios and performance expectations.
• Work closely with architects, developers and testers throughout implementation.
• Maintain functional documentation as projects evolve.
• Participate in defect reviews and UAT campaigns.
• Investigate data directly when analysing or qualifying defects.
Functie-eisen
Required Experience & Skills
• Minimum 3 years of professional Functional Analysis experience within the last 8 years.
• At least 2 years of proven experience with traffic management systems in the railway sector or comparable operational environments, such as aviation, ports, logistics or utilities.
• Professional experience specifying or analysing system-to-system integrations, including REST/SOAP APIs or message/event-based interfaces, payload structures such as JSON/XML and error handling.
• Ability to independently write SQL queries, including SELECT, JOIN, aggregation and filtering, to investigate data, validate business rules or analyse defects. This must be clearly demonstrated with an example in the CV.
• Experience producing functional specifications, user stories, acceptance criteria, business rules and system behaviour.
Languages
• English: C1 or higher, written and spoken.
• Dutch or French: minimum B2, spoken.
Specifications and project documentation are produced in English. Dutch or French is required for workshops, defect reviews and day-to-day communication with stakeholders.
Additional Relevant Experience
Experience with the following will strengthen the profile:
• BPMN, UML, use cases or equivalent modelling techniques.
• Traceability between regulatory requirements, functional requirements, interfaces and tests.
• XML/XSD, JSON and OpenAPI.
• Error handling, message sequencing and versioning.
• Conceptual and logical data modelling.
• Master and reference data.
• Data-quality initiatives.
• Defect triage, migrations, test preparation and UAT.
Practical Information
• Hybrid working arrangement.
• Minimum 2 days per week on-site.
• Additional on-site presence may be required for workshops, incidents or release activities.
• This assignment starts in January 2027.
