Data Migration Specialist-Contractual Role

Role- Data Migration Specialist

Vistra is a global leader in corporate services, and we’re in the middle of one of the most ambitious payroll transformation programs in our history. Our purpose is progress: we remove the complexity of global business so our clients can move forward without friction.

Right now, Vistra is migrating payroll client entities from our legacy middleware application - OverseasConnect (OSC) - into our target iiPay global payroll platform; a complex, high-stakes program that demands more than a lift-and-shift.

You will report into a matrixed reporting structure, working directly with the Lead Data Migration Engineer & Architect and Migration Project Manager and working closely with leadership team members such as EVP Operations and Payroll, EVP Business Applications.
