Senior Business Analyst

📍 Brussels (hybrid) | Freelance or Permanent consulting contract | Minimum 1-year assignment

1/ ABOUT THE ROLE

Our client is a leading Belgian Property & Casualty insurer operating in the Commercial Lines / Corporate segment.

As part of a multi-year transformation programme, they are modernising their insurance platforms, replacing legacy product administration and offer/contract systems with a modern API-driven target architecture.

The programme aims to:

• Improve underwriting efficiency
• Accelerate time-to-market for product changes
• Improve broker and customer response times

The target architecture is built around:

• A shared product catalogue
• A shared decisioning layer
• A unified API layer serving multiple front-end channels

Several legacy systems are being decommissioned in parallel as capabilities are migrated to the new platform. To support this transformation, we are looking for a Senior Business Analyst who can lead migration workstreams end-to-end, from an initial, often ambiguous brief through to a fully validated and implementation-ready solution.

2/ WHY THIS ROLE IS DIFFERENT

This is not a traditional Business Analyst position where requirements arrive fully defined.

You will be given a problem statement that may be incomplete or inaccurate and will be expected to:

• Identify the actual business problem
• Determine who holds the required knowledge
• Validate assumptions
• Build a clear and robust understanding before moving into solution definition

If you enjoy bringing clarity to complex and ambiguous situations, this role is for you.

3/ KEY RESPONSIBILITIES

• Investigate and redefine the underlying business problem before starting detailed analysis.
• Identify, engage, and sequence stakeholders effectively to obtain the right information.
• Build structured business and data models for insurance products and processes within scope.
• Challenge and validate those models until they are robust and defensible.
• Produce clear, structured business requirements and business rule documentation.
• Track, manage, and resolve open questions throughout the analysis lifecycle.
• Present findings, recommendations, and analysis outcomes to stakeholders and sponsors.
• Ensure the quality and completeness of your own deliverables before submission.

4/ REQUIRED EXPERIENCE

Must have

• Senior Business Analyst experience (typically 5+ years) in complex systems transformation or process change programmes.
• Strong experience with structured business modelling and/or data modelling (UML, object-oriented modelling, or comparable methodologies).
• Experience documenting business requirements and business rules using structured and unambiguous formats.
• Fluency in French and English.
• Ability to work independently with incomplete information and uncover the real business requirement.

Nice to Have

• Insurance industry experience, ideally Property & Casualty or Commercial/Corporate Lines.
• Experience in legacy-to-target migrations or platform decommissioning programmes.
• Dutch language skills.
• Experience with formal business rule notation and/or requirements engineering frameworks.

5/ WORKING ENVIRONNEMENT

• High autonomy with ownership of dedicated workstreams.
• High trust and high accountability culture.
• Well-established delivery processes, documentation standards, and quality controls.
• Structured environment that values analytical rigour and evidence-based decision making.

6/ TECHNICAL ENVIRONMENT

• Insurance product, activity and clause modelling.
• Product hierarchies, eligibility rules and coverage structures.
• Current-state / target-state architecture and capability mapping.
• Formal business rule authoring.
• Internal knowledge management tools for tracking decisions, models and open questions.
• Documentation produced primarily in Microsoft Word.
