Why Castelion, Why Now
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.
Senior Supply Chain Planner
As a Senior Supply Chain Planner, you will own planning execution for assigned programs, commodities, or product areas and help translate engineering and program requirements into executable, resilient supply plans. You will operate with a high degree of autonomy, use data and sound judgment to prevent hardware blockers, and influence cross-functional partners across sourcing, engineering, quality, manufacturing, finance, and program management.
This role is intended for a planner who can independently manage complex work, lead resolution of material and capacity risks, improve planning processes, and serve as a trusted resource to less-experienced planners. At the upper end of the level, you will be expected to shape planning strategy across a broader program or commodity and lead initiatives without formal people-management responsibility.
