About the role

ABOUT POSEIDON AEROSPACE: Poseidon Aerospace is reimagining how the world moves goods.
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.

Design and deliver tooling, jigs, and fixtures for aircraft assembly and fabrication processes
Rapidly prototype manufacturing solutions to support evolving aircraft designs and assembly sequences
Conduct first article inspections and dimensional validation of tooling to ensure design intent is met
Collaborate with design engineers to provide DFM feedback and influence part designs for improved manufacturability
Develop and document assembly procedures, work instructions, and tooling usage guidelines
Troubleshoot and iterate on tooling designs based on real-world assembly feedback from the production floor
Maintain and improve existing tooling as aircraft designs evolve through development cycles
We build and operate full-size autonomous cargo aircraft; Heron, a seaplane, and Egret, a STOL aircraft; each capable of carrying two tons of payload over a thousand nautical miles.
As a Manufacturing Engineer at Poseidon Aerospace, you will design and machine the tooling that brings our composite aircraft to life.
You'll own the complete process from CAD design through CAM programming to running parts on our mills and routers, delivering functional jigs and fixtures on startup timelines.

Proficiency in CAD software (Fusion, SolidWorks, CATIA, NX, or similar) for designing tooling, fixtures, and jigs
Strong understanding of GD&T and ability to apply proper tolerancing to tooling designs
Knowledge of composite materials and their unique tooling requirements (layup surfaces, cure tooling, trim fixtures)
Experience with metrology equipment (calipers, micrometers, height gauges) and inspection techniques
Ability to balance speed with precision-knowing when "good enough" is appropriate versus when tight tolerances are critical
Hands-on CAM programming experience and ability to machine own parts on vertical mills and multi-axis CNC equipment
Understanding of design for manufacturing principles and common composite manufacturing processes (layup, bonding, trimming, drilling)
Self-directed problem solver comfortable working independently while supporting a small, fast-moving team

At Poseidon Aerospace, we value diverse perspectives and are always looking for talented individuals with unconventional backgrounds.
