Workday HCM Data Migration Consultant

About this role

The Role
We need a Workday HCM specialist who has done the hard data migration work — not just the easy stuff. This engagement involves acquisition-driven migrations, Workday-to-Workday tenant consolidations, and a mid-year payroll cutover. If mid-year payroll conversions make you nervous, this isn't your role. If you've survived one and know why they're brutal, keep reading.
What You'll Own

• Data migration strategy and execution for acquired entities into Workday HCM

• Workday-to-Workday data migration — legacy tenant to target tenant

• Parallel testing for payroll, benefits, and 401(k)

• Mid-year payroll conversion planning and execution

• Benefits and 401(k) data validation across cutover periods

The Critical Requirement
This engagement also requires experience with ring-fencing — specifically, isolating an acquired entity as a standalone legal entity within Workday while the broader integration work continues. This includes org structure, security domains, payroll processing, and benefits segmentation for that entity. If you don't have direct experience here, please say so upfront.
You Must Have

• 7+ years of Workday HCM implementation and data migration experience

• Proven experience migrating acquired company data into Workday

• Direct experience with Workday-to-Workday tenant migrations

• Payroll parallel testing and mid-year payroll conversion — hands-on, not advisory

• Benefits and 401(k) data migration and validation

• Ring-fencing / standalone entity configuration experience (required — not preferred)

Nice to Have

• Workday certification in HCM or Payroll

• Experience with M&A integration timelines

• EIB and iLoad proficiency for data loading

Honest Note
The mid-year payroll cutover is the hairiest piece of this engagement. We need someone who has done it, knows the risks, and won't be surprised by what they find. If this matches your background, reach out. If you know someone who fits, send them our way.
No Third Party
