We are growing quickly and looking for a Compensation Accounting Manager to join our Finance team.

This is an exciting opportunity for a technically strong accounting professional to own the full accounting lifecycle for compensation-related activity, including payroll, bonuses, equity, benefits, reconciliations, and close support across a multi-entity, multi-country environment.

About the Compensation Accounting Manager Role

This individual will partner closely with Compensation, Recruiting, FP&A, and Payroll to ensure compensation activity is recorded accurately, reconciled thoroughly, and supported by clear documentation.

We value talent from all backgrounds; however, for this position, we are unable to sponsor employment visas. We welcome applications from individuals who are already authorized to work in the United States without sponsorship.
