THE ROLE

Mach Industries is seeking a Principal Reliability Supplier Industrialization Engineer focused on mechanical hardware, composites, and castings to qualify, develop, and scale suppliers that produce reliable components to engineering, manufacturing, and system requirements. You will translate mechanical design intent into capable material, tooling, molding, casting, finishing, inspection, and production processes. This role spans Mechanical Engineering, Structures, Supply Chain, Quality, Manufacturing, Test, and suppliers from early design reviews through prototype, qualification, production, and field support. The work is hands-on and requires regular engagement with composite fabrication, casting processes, inspection data, supplier process development, and hardware qualification.

KEY RESPONSIBILITIES

- Lead supplier industrialization for mechanical components, composite structures, castings, and related hardware from design release through production readiness.

- Support mechanical design reviews by identifying material, tooling, molding, casting, tolerance, inspection, and process risks.

- Develop commodity FMEAs, supplier qualification requirements, control plans, inspection methods, and acceptance criteria for critical mechanical hardware.

- Assess supplier capability across composite layup, curing, infusion, molding, casting, heat treatment, finishing, non-destructive inspection, and dimensional inspection.

- Establish first article requirements, process-validation plans, material-control methods, inspection coverage, and objective evidence for supplier production readiness.

- Monitor supplier performance using quality, delivery, yield, nonconformance, process-capability, material, and inspection data.

- Lead root-cause and corrective-action investigations for recurring supplier nonconformances, porosity, delamination, dimensional variation, surface defects, and process escapes.

- Support obsolescence, redesign, alternate-source, and supplier-transition activities while preserving configuration integrity and production continuity.

- Feed supplier lessons learned into mechanical design standards, manufacturing methods, inspection strategies, sourcing decisions, and reliability-growth activities.

- Up to 100% travel

REQUIRED QUALIFICATIONS

- Bachelor's degree in mechanical engineering, materials engineering, manufacturing engineering, or equivalent professional experience.

- Ten or more years of experience in supplier industrialization, manufacturing engineering, supplier quality, composites, castings, or related mechanical hardware.

- Experience with composite fabrication, casting processes, mechanical drawings, GD&T, inspection methods, or material and process controls.

- Ability to evaluate supplier processes, identify technical risks, and define practical controls for complex mechanical hardware.

- Ability to communicate clearly with suppliers and cross-functional teams while managing multiple industrialization activities.

PREFERRED QUALIFICATIONS

- Experience with aerospace, defense, propulsion, automotive, or other high-reliability mechanical hardware.

- Experience with autoclave or out-of-autoclave composites, prepreg, resin infusion, compression molding, or bonded structures.

- Experience with investment casting, sand casting, precision castings, heat treatment, machining allowances, or casting simulation.

- Experience with NDI or NDT methods, material certification, special-process qualification, or aerospace and defense quality requirements.

- Experience supporting prototype-to-production transitions in a startup, high-growth manufacturing, or regulated hardware environment.

- Experience with FMEA, control plans, first article inspection, process validation, and structured root-cause and corrective-action methods.
