Job summary

Poseidon Aerospace seeks a Composites Engineer to bridge design and fabrication for advanced aerospace structures. You will develop and support molding, layup, bonding, and cure processes while ensuring manufacturability and quality on prototype and production airframe components.

You will collaborate with design engineers, assist technicians on the shop floor, and drive process improvements. Strong CAD, GD&T, and problem-solving in a fast-paced environment are essential.

Qualifications

• Bachelor’s degree in Mechanical, Aerospace, Manufacturing, or Materials Engineering or equivalent technical experience.
• 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.

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.
