Customer-Facing Product Development
Partner with customer design, mechanical, and manufacturing teams during early development phases
Provide DFM (Design for Manufacturability) and DFA (Design for Assembly) recommendations
Support design reviews, tolerance analysis, and material selection
Process Development & Industrialization
Develop and validate manufacturing processes for precision components and assemblies (glass, metal, composites, etc.)
Define process flows, tooling, fixtures, and control plans
Lead process qualification (IQ/OQ/PQ) and capability validation
NPI Program Execution
Drive end-to-end NPI builds (EVT / DVT / PVT through mass production)
Identify technical risks and implement mitigation strategies during ramp
Coordinate cross-functional teams across engineering, quality, and operations
Cross-Regional Engineering Collaboration
Translate customer requirements into actionable specifications for global manufacturing sites
Partner with Asia and Mexico teams to ensure process readiness and yield targets
Support onsite builds and production ramp as needed
Quality & Continuous Improvement
Analyze yield issues and lead root cause analysis (RCA)
Implement corrective actions to improve quality and process stability
Support sustaining engineering activities and engineering change management (ECO/ECN)
