We are growing quickly and looking for an 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 Accounting Manager Role
