Senior Business Analyst (EU/Oracle/Legacy)

We are re-platforming a national public-sector system in the EU: ~750 screens of a legacy client-server 4GL (Uniface), rebuilt as a modern Java/Spring + React application on top of an Oracle database.

The hardest question on this project is not "does the new code work" — it is "does the new system do exactly what the old one does". The legacy system has decades of business rules encoded in screens and PL/SQL, much of it undocumented. Someone has to dig those rules out, write them down, agree them with the client, and turn them into the criteria that decide whether each migration wave goes live.

That someone is you. You own the business specification for every agenda, you work directly with the client's domain experts, and you hand the QA Lead a specification precise enough to be tested against without interpretation. Specification and verification are two roles on this project, but they share one artifact — so you stay close to QA, and you are expected to roll up your sleeves on QA work when a wave needs it.
