If you are excited by building real hardware, scaling production, and owning critical systems from the ground up, we want to hear from you. Over the coming months, we will be hiring across a range of functions, including manufacturing, engineering, facilities, operations, test, quality, EHS, supply chain, and program support.

Castelion is building the future of American hypersonic defense - and Rio Rancho, New Mexico will be a central part of that mission.

We’ve recently broken ground on a 1,000+ acre hypersonic production campus, purpose-built to support high-cadence manufacturing, testing, and final assembly of advanced long-range systems. This site represents a major step forward in Castelion’s trajectory and a clear signal of both the speed and seriousness with which we are executing.

Castelion is three years into its journey and entering a defining moment. With more than 25 flight tests completed, active U.S. Army and U.S. Navy integration contracts, over $450M in funding, and a newly launched manufacturing campus in New Mexico, we are moving from proving capability to delivering deterrence at scale.

Our mission is urgent and undeniable: hypersonics only matter if they can be built in the numbers deterrence requires. That belief has earned us unprecedented early buy-in from military leadership and customers - and it demands speed, ownership, and execution from our team.

This is a ground-floor opportunity with real responsibility, real consequences, and real visibility. Castelion is not a place to observe from the sidelines. It’s a place for driven, talented, mission-oriented builders who want to move fast, take ownership, and help rebuild America’s Arsenal of Freedom when it matters most.

You may be a fit if you:

• Want to work on real systems, not paper designs
• Thrive in fast-moving, hardware-rich environments
• Take ownership and responsibility seriously
• Care deeply about mission, quality, and execution
• Want to help build scalable manufacturing and test infrastructure from the ground up

We will be reaching out as we get roles posted through the coming months, please drop your resume and a note on where you can best contribute
