• Own qualification and release of additional manufacturing capacity (sites, lines, tools) 

• Ensure readiness for high-volume production, including alignment of test capability and manufacturing flow 

• Partner with Operations on demand/capacity balancing and risk mitigation 

Test Strategy Execution in Production 

• Drive production test optimization, including test conversions across ATE platforms 

• Ensure correlation, stability, and scalability of test solutions in manufacturing 

• Support test coverage improvements, cost optimization, and hardware/software transitions 

• Partner with Test Engineering and Test Architecture teams for long-term platform strategy 

Change Management & Product Lifecycle Support 

• Own execution of PCNs, ECOs, and manufacturing transfers 

• Ensure robust change control processes with minimal disruption to production 

• Support EOL and last-time-buy activities and long-term product sustainability planning 

Cross-Functional Leadership 

• Lead global sustaining engineering teams across multiple sites 

• Act as primary interface between Product Engineering, Test, Quality, Reliability, and Operations 

• Drive alignment on priorities, issue escalation, and factory performance improvement 

• Build strong engagement with OSATs and internal manufacturing partners 

Organization & Business Leadership 

• Own sustaining engineering roadmap, metrics, and performance tracking 

• Manage headcount, budget, and capital planning related to sustaining/test infrastructure 

• Build and develop a high-performing global team 

• Drive standardization, best practices, and scalable processes across product lines 

Required Qualifications 

• Bachelor's degree in Electrical Engineering or related field (advanced degree preferred) 

• 12-15+ years of semiconductor experience across Product Engineering, Test Engineering, or Manufacturing 

• Proven leadership experience managing teams in high-volume production environments 

• Strong expertise in:  

• Yield analysis and improvement 

• Failure analysis and root cause methodologies 

• Semiconductor manufacturing flows (fab, assembly, test) 

• ATE systems and production test methodologies 

Preferred Qualifications 

• Experience with power semiconductors (modules, controllers, PMICs, Si/SiC/GaN) 

• Experience with OSATs and global supply chain manufacturing 

• Strong background in test conversions and ATE platform strategy 

• Familiarity with data center power applications and high-reliability requirements
