Global Mobility Lead

IMC is seeking a Global Mobility Lead to join our Global Total Rewards Team to build and lead our global mobility program. Reporting to the Head of Total Rewards, this role will own the full spectrum of global mobility - from policy design and governance to tax compliance, immigration, and assignee experience - and will serve as IMC's primary subject matter expert on all matters related to cross-border employment.
As a strategic partner, you will work across HR, Finance, Legal, and senior business leadership to ensure that our mobility program is structured, competitive, compliant, and cost-effective. This is an individual contributor role, with strong dotted line relationships within HR. You will manage external consultants and vendors, and will be responsible for establishing the infrastructure, governance, and reporting capabilities that a program of this scale requires.
