Senior Functional Analyst (with business analysis skills)

About the mandate

A large organisation is running a multi-year transformation project around a central platform for member data, contributions, premiums and reimbursements. The platform supports federal and regional processes and is linked to accounting, SEPA payments and analytical reporting. The programme combines the migration from an existing central member and financial management system with new bespoke functionality. As a freelance Senior Functional Analyst, you translate complex business processes into clear, feasible functional specifications. You work closely with domain experts, product owners, testers, developers and suppliers. You verify data migrations and financial calculations, and you carry out the business analysis yourself when needed. The working environment is hybrid, with meetings at the office in Brussels.
