Inventory Lead Torrance, CA Supply Chain

Castelion is moving incredibly fast to develop and deliver advanced defense systems at a time when execution matters more than ever. We believe focus, ownership, and excellence are decisive advantages - and we're building a world-class team to turn bold ideas into real capability.

This is a rare opportunity to join at an early stage, where you'll have significant ownership, collaborate with exceptional teammates, and make a direct, measurable impact on our mission and the future of the company - regardless of your function.

As an Inventory Lead, you'll lead day-to-day inventory operations across physical and system environments, ensuring materials are accurately received, tracked, stored, issued, and available to support production schedules. You will provide direction to Inventory Specialists and material-handling personnel while serving as a key point of contact for Purchasing, Production, Supply Chain, and other cross-functional teams.

This is a hands-on leadership role requiring strong attention to detail, sound judgment, clear communication, and a continuous improvement mindset. You will own inventory accuracy, help establish operational priorities, resolve material issues, and ensure that physical inventory aligns precisely with ERP data. Your work will directly support production readiness, material flow, operational excellence, and the timely delivery of Castelion hardware.
