Rio Rancho, US · Full-time · $140,000 – $180,000

About this role

Castelion is bringing a new approach to defense development and production, focusing on short, iterative design cycles, rapid testing in development, and modern commercial manufacturing strategies for production at scale. The company designs, builds, and tests next-generation long-range strike weapons systems to give America and its Allies a definitive edge. The Senior Propulsion Engineer designs solid rocket motor primary and secondary structures along with propulsion components, emphasizing schedule, affordability, and scale.

Translate project objectives into cost-effective designs that can be produced at scale the Castelion way. Spearhead the creation of innovative solid rocket motor designs, demonstrating autonomy even with limited expert guidance. Actively engage in the assembly, testing, and troubleshooting of prototypes and production builds, providing expert guidance as necessary.

Use rapid iteration cycles to validate product performance and facilitate necessary design adjustments. Produce, evaluate, and authorize CAD models and drawings adhering to internal standards and ASME Y14.5-2009 guidelines. Collaborate with supply chain to ensure seamless support and adapt designs to mitigate availability risks and time delays.

Provide thorough assessments and resolutions for any discrepancies in hardware, including supporting analyses when required. Work in a fast-paced environment supporting rapid product development for high-rate production. Demonstrate bias to action and creative problem solving by questioning assumptions and implementing breakthrough ideas.

Requirements

  • Bachelor's or advanced degree in aerospace engineering, manufacturing engineering, materials engineering, mechanical engineering or physics
  • 5+ years of mechanical or fluids design, analysis, or build experience (student project team, university rocketry club and internship experience counts)
