• Define and execute the manufacturing footprint and operating model strategy, blending company-run and contract-manufactured capacity to exceed customer expectations.
• Establish a consistent, data-driven manufacturing system (standard work, statistical process control, KPIs, governance, and audit cadence).
• Drive field reliability, first-pass yield, and cost-per-watt improvements through Lean, Kaizen, automation, and design-for-manufacturability feedback to the factory and matrixed organizations.
• Manage CM operational performance, including capacity commitments, throughputs, cost models, quality agreements, and continuous improvement planning.
• Build and develop a high-performing manufacturing engineering bench, with strong plant operational excellence, and continuous improvement capability.
• Continuously drive innovation in manufacturing processes, automation, and test as a technology-based company, and lead factory start-ups and capacity expansions on schedule and on budget.
