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.

Senior Technical Recruiter
As a Senior Technical Recruiter at Castelion, you will play a critical role in building an elite engineering and technical organization responsible for developing and manufacturing next-generation hypersonic defense systems.

This is a highly hands-on role for a recruiter who knows how to build pipelines from scratch, navigate competitive talent markets, and consistently deliver results. We are looking for someone who takes extreme ownership, operates with urgency, and understands that great recruiting requires much more than managing applicants and coordinating interviews.
