Manufacturing Engineer – Composite Motor Cases

Castelion Corporation•Torrance, CA

About The Position

The Manufacturing Engineer – Composite Motor Cases will own the development, industrialization, and production of manufacturing processes used to build advanced composite solid rocket motor cases. This is a highly hands-on role supporting the transformation of filament-wound composite structures and associated components into completed motor-case assemblies. Depending on experience and program needs, engineers in this role may own processes including insulation and rubber application, bonding, cure, hardware integration, assembly, tooling, or other composite motor-case manufacturing operations. You will work closely with Filament Winding, Design, Materials, Quality, Propulsion, and Production teams to develop robust manufacturing processes and transition hardware from development into repeatable production.

Requirements

  • B.S. in Mechanical, Aerospace, Manufacturing, Materials Engineering, or related field.
  • Experience in manufacturing engineering or production of complex hardware.
  • Experience developing and improving manufacturing processes.
  • Ability to develop tooling, work instructions, and process controls.
  • Demonstrated ability to solve manufacturing problems in a hands-on production environment.

Nice To Haves

  • Experience with composite structures, aerospace, defense, or propulsion manufacturing.
  • Experience with bonded assemblies, adhesives, rubber, insulation, cure, or structural integration.
  • Experience taking composite hardware or manufacturing processes from development into production.
  • Experience with manufacturing tooling, process qualification, or production scaling.
  • Experience working across multidisciplinary engineering and production teams.

Responsibilities

  • Own manufacturing processes within the composite motor-case production flow.
  • Develop and optimize bonding, cure, integration, assembly, and material application processes.
  • Develop tooling, fixtures, work instructions, routings, and process controls.
  • Support insulation, rubber, adhesives, and other material systems used in composite motor-case manufacturing.
  • Integrate filament-wound structures and associated hardware into completed motor-case assemblies.
  • Lead process qualification and production-readiness activities.
  • Partner with Filament Winding, Design, and Materials Engineering to ensure manufacturability and robust processing.
  • Partner with Quality to establish inspection requirements and process controls.
  • Lead root-cause investigations and resolve manufacturing issues.
  • Develop capacity and production scaling plans for assigned processes.
  • Support supplier development and outsourced manufacturing as needed.
  • Provide hands-on support to technicians during development and production builds.
