• Establish and enforce tooling design standards, documentation practices, drawing packages, and configuration control.

• Drive Design for Manufacturability and Design for Tooling input into new product introduction and design changes.

• Partner with Manufacturing Engineering and Automation & Controls on work-cell concepts, fixture interfaces, and semi-automated or automated tooling solutions.

• Oversee tooling qualification, first-article tryouts, process capability assessments, and production release.

• Manage tooling maintenance, spare-parts strategy, life tracking, and continuous improvement of existing tooling.

• Coordinate with suppliers and internal machine shops on tooling fabrication, materials, and lead times.

• Ensure tooling designs support safety, contamination control, and compliance requirements in energetic-materials facilities.

• Support facility ramp and production scaling at Midland, TX and the Project Ranger campus in New Mexico.

• Report tooling readiness, risk, cost, and schedule metrics to senior manufacturing leadership.

Required Qualifications

Education: Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or related field required. Master’s degree preferred.

Experience:

• 8+ years of tooling design or manufacturing engineering experience in aerospace, defense, or complex composite/precision assembly.

• 3+ years leading engineers or serving as a technical lead on tooling programs.

• Demonstrated success designing and releasing production tooling for composite structures, bonded assemblies, or propulsion hardware.

Technical Skills

• Strong proficiency in 3D CAD (SolidWorks or NX) for fixture and tooling design.

• Experience with GD&T, tolerance stack-up, fixture concepting, and manufacturing documentation.

• Working knowledge of composite layup/winding fixtures, bonding fixtures, machining fixtures, and assembly tooling.

• Familiarity with tooling materials, surface treatments, and design for wear, cleanability, and maintainability.

• Ability to interface with automation systems and understand work-cell constraints.

• Understanding of aerospace quality systems (AS9100) and configuration control.

Preferred Experience

• Direct tooling experience on solid rocket motor cases, nozzles, liners, or missile composite structures.

• Background in fast-paced defense or space manufacturing environments.

• Experience scaling tooling from development to high-rate production.

• Prior people leadership of a tooling or fixture design team.

• Familiarity with ITAR programs, classified manufacturing, and energetic-materials facilities.

• Track record reducing tooling-related scrap, cycle time, or changeover time.

Soft Skills

• Proven ability to lead and develop tooling engineers while retaining technical credibility.
