Job summary

Poseidon Aerospace is seeking a Composites Engineer to bridge design and fabrication for advanced aerospace structures. You will develop and document manufacturing processes for composite airframe components and work closely with production teams to ensure manufacturability and quality.

The role involves tool development, process optimization, and collaboration with design engineering to transition designs to production, while mentoring technicians and contributing to lean and digital

Qualifications

• Bachelor’s degree in Mechanical, Aerospace, Manufacturing, or Materials Engineering
• 2–5 years of hands‑on composite fabrication or manufacturing engineering experience in aerospace or related industries
• Strong working knowledge of composite materials (carbon fiber, fiberglass, epoxy systems) and associated processes (hand layup, resin infusion, RTM, bonding)
• Demonstrated experience supporting technicians and shop‑floor operations
• Ability to design and develop tooling and fixtures using CAD software
• Strong understanding of GD&T and the ability to apply proper tolerancing to tooling designs and composite fabrication drawings

Responsibilities

• Design, fabricate and procure tooling, molds, jigs, and fixtures required for fabrication and assembly
• Develop and document manufacturing processes for composite airframe components, including layup, bonding, curing, trimming, drilling, and assembly
• Collaborate closely with design engineering to ensure manufacturability, structural integrity, and production efficiency of composite parts and assemblies
• Work directly with technicians on the floor to support prototype builds, troubleshoot issues, and optimize build quality and efficiency
• Define material handling, kitting, and cure cycle parameters to ensure process consistency and compliance with specifications
• Support prototype builds and transition new designs to production, troubleshooting issues on the shop floor
• Develop detailed work instructions, travelers, and manufacturing documentation
• Analyze process capability and identify opportunities for cost reduction, yield improvement, and defect prevention
• Support non‑conformance investigations and implement corrective/preventive actions
• Interface with suppliers on composite materials, tooling, and equipment
• Provide training, mentoring and technical guidance to production technicians on new processes or tooling
• Maintain accurate BOM information for all airframe components and subsystems
• Contribute to continuous improvement initiatives, lean manufacturing efforts, and digital manufacturing integration
