Job description

About Poseidon Aerospace:

Poseidon Aerospace is reimagining how the world moves goods. We build and operate full-size autonomous cargo aircraft - capable of carrying two tons of payload over a thousand nautical miles. From remote communities to contested logistics operations, our platforms unlock a new cost curve for air freight, making it faster, cheaper, and accessible anywhere it's needed. Headquartered in the San Francisco Bay Area with locations in Washington DC, Oregon, and Maine; we're building something consequential.

As a Composite Technician at Poseidon Aerospace you will be responsible for the fabrication and assembly of advanced composite components for aerospace prototype and development programs. This role requires a strong understanding of composite materials, custom tooling, and hands-on manufacturing techniques. The ideal candidate is a skilled fabricator who can interpret engineering concepts, build tooling or jigs as needed, and support one-off as well as high-rate composite builds from start to finish.

Responsibilities:

• Fabricate composite components using hand layup, resin infusion, and bonding techniques.
• Build, modify, and maintain custom molds, fixtures, and jigs to support prototype part fabrication and assembly.
• Collaborate closely with engineers and designers to interpret 3D models, drawings, and verbal instructions.
• Develop and refine layup methods, cure cycles, and fabrication approaches for new designs.
• Set up and monitor vacuum bagging, and oven curing processes.

• Strong problem-solving and troubleshooting skills in a fast-paced, dynamic environment.
• Comfortable working with epoxy resins, adhesives, and solvents while following safety procedures.

Nice to Have:

• Experience fabricating or modifying jigs, fixtures, or tooling using metal, wood, or composite materials.
• Familiarity with precision measurement tools and quality inspection processes.
• Familiarity with 3D modeling software.
• Experience working in a fast paced prototyping environment and large scale production.
