About The Position

Castelion is seeking a hands-on, high-agency NX Engineer to own the Siemens NX and support Teamcenter environment used by design engineers. The engineer will be the technical expert for NX across Castelion’s hypersonic vehicle programs, maintaining a fast, stable, and standardized CAD/PLM toolchain that helps engineers progress from concept to flight hardware. The role involves solving engineering support issues both directly with users and through scalable tools and processes. The position is based on-site in Torrance five days a week, with occasional travel to other U.S. sites. The role may require access to classified information or restricted U.S. Government sites, systems, or information. Candidates must be U.S. citizens and be able to obtain and maintain any required government security clearance or authorization. Access to export-controlled information is required, and hiring is contingent on eligibility to access that information without additional export licensing. Castelion develops and produces advanced defense systems using short, iterative design cycles, rapid development testing, and modern commercial manufacturing strategies. The company says the role offers significant ownership and direct impact on its hypersonic vehicle programs. Benefits listed include long-term equity, paid time off, company-paid holidays, health coverage, paid parental leave, a fitness stipend, onsite EV charging, catered meals, food during high-demand periods, and a stocked kitchen.
