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.
Castelion is building affordable, rapidly producible hypersonic strike weapons for the U.S. military. We move quickly from design to flight test to production, and we are standing up R&D manufacturing at our facility in Midland, Texas.
