About the position

You’ll be working on the foundational system in a complex, large-scale transformation chain of actuarial data. This platform serves the Global Office of a leading insurance group, providing the first touchpoint for data coming from over 40 countries. These countries are required to deliver and upload their actuarial extracts into the system within tight timeframes, forming the data bedrock for financial reserves calculations across all regions.

Your Role

As an PL / SQL Engineer, you'll be responsible for uploading and validating large volumes of actuarial datasets, ensuring their technical accuracy (formatting, structure, compliance). You will be at the critical entry point of a global data flow — where quality, speed, and attention to detail are essential.

This is not just about uploading files. It’s about handling 200+ datasets, arriving in rapid succession, identifying and resolving errors, and keeping the flow moving for downstream actuarial processing. You'll collaborate closely with senior technical experts and functional analysts and be a key player in communication with global teams.

While full automation is on the near horizon, this role currently demands agility, precision, and strong communication skills more than advanced technical development. You’ll need to listen carefully, adapt quickly to priorities, and keep the team moving forward under pressure.
