About The Position

iRESTORE is seeking a Fulfillment Operations Supervisor to oversee the day-to-day performance of our multi-node fulfillment network across our La Mirada, CA warehouse and third-party logistics (3PL) partner supporting the Eastern U.S. In this role, you will own fulfillment execution across both locations, ensuring orders are routed and shipped accurately, on time, and at the right cost. You will serve as the primary operational partner to our 3PL and oversee order routing, inventory visibility, systems integrations, shipping performance, and cost reconciliation across the network. This is a hands-on role for an operationally strong problem solver who can identify issues quickly, coordinate across internal and external partners, and continuously improve fulfillment performance as the business scales. You will work closely with the Warehouse Operations Supervisor, who leads physical warehouse operations in La Mirada, and report to the eCommerce Operations Manager.
