Senior Manufacturing Engineer – Solid Rocket Motor Production

Castelion is bringing a new approach to defense development and production: one that focuses on short, iterative design cycles, rapid testing in development, and modern commercial manufacturing strategies for production at scale. We’re designing, building, and testing next generation long range strike weapons systems to give America and its Allies a definitive edge and deter future conflicts.

Role: Castelion is seeking a mechanically minded and autonomously driven manufacturing engineer to lead day to day production of solid rocket motors, to include manufacturing processes like machining, propellant dispensing and casting, non-destructive evaluation, and mechanical assembly. This role will report directly to Castelion’s Head of Manufacturing and coordinate closely with other members of the engineering leadership team to eliminate roadblocks to achieving the company’s technical goals.

  • Develop process and factory design to transition from development to production rates of 1,000s of units per year
  • Develop and refine process documentation including build instructions, safety standards, and mBOMs

  • Work closely with Castelion supply chain to develop new and existing suppliers
  • Participate in design reviews to drive design for manufacturing (DFM)

Basic Qualifications:

  • Experience Manufacturing Integrated Systems. Ability to drive for and understand the fundamental reason for why a tool or piece of infrastructure is important to the company’s technical goals. Experience managing suppliers for large parts and a willingness to get on site with vendors to solve issues and get delivery of parts on time
  • High Commitment, High Initiative. A successful candidate will have a genuine passion for Castelion’s mission and consistently look for ways to contribute to the company’s technical goals and prevent hardware blockers

  • Clear Communicator. Capable of tactfully managing relationships with stakeholders to achieve company-desired outcomes without compromising relationships. Emails, IMs and verbal interactions are logical, drive clarity, and detailed enough to eliminate ambiguity

  • 5+ Years of Manufacturing, Fabrication, Assembly, or Testing Experience

Preferred Qualifications:

  • Experience in solid rocket motor fabrication
  • Experience with chemical dispensing
  • Experience with ordnance
