Job description

This program involves:

• Complex data migration spanning 16 years of legacy data,

The Data Integration Lead is responsible for designing, preparing, and executing the data migration and integration strategy, while ensuring alignment with business processes and future reporting and data usage needs.

As the owner of the data migration and integration strategy, the Data Integration Lead will design, prepare, and execute data flows that align technology with real business processes and long-term reporting and analytics needs.

Reporting to Transformation Program Leadership, this role operates at the intersection of business processes, data architecture, and system integration, requiring both strategic thinking and hands-on execution, offering a rare opportunity to combine strategic influence with hands-on execution and leave a lasting impact on NATEK’s digital foundation.
