Airlines/Aviation
Responsibilities
Design and deliver tooling, jigs, and fixtures for aircraft assembly and fabrication processes
Program and machine custom tooling components using CAM software and CNC equipment
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
Qualification
Required
Proficiency in CAD software (Fusion, SolidWorks, CATIA, NX, or similar) for designing tooling, fixtures, and jigs
Hands-on CAM programming experience and ability to machine own parts on vertical mills and multi-axis CNC equipment
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
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
Ability to balance speed with precision—knowing when 'good enough' is appropriate versus when tight tolerances are critical
Preferred
Experience with Fusion 360 for integrated CAD/CAM workflow
