• Understand kitting, staging, hardware integration, torque requirements, and final assembly labor
• Estimate wire harness manufacturing including cut, strip, crimp, terminate, continuity testing, shielding, grounding, connectors, backshells, and strain relief

Tools, Systems, and Data

• Use job-based ERP, MRP, and MES systems for estimating and routing development
• Experience with ProShop ERP, Epicor, JobBOSS, SAP, or Oracle strongly preferred
• Utilize CAD viewers and technical documentation systems

Required Qualifications

• 5+ years of experience in manufacturing engineering with direct cost estimation and quoting responsibility
• Proven experience estimating mixed-process jobs across machining, fabrication, welding, assemblies, and wire harnesses
• Strong understanding of CNC machining, fabrication, welding, and assembly processes
• Experience in aerospace or defense manufacturing environments
• AS9100 environment experience
• Strong written documentation of assumptions, exclusions, and risks
• Ability to challenge undefined or unrealistic customer requirements

Preferred Experience
