• Support investigations and resolution activities related to:
  • Nonconformances
  • Deviations
  • CAPAs
  • Customer complaints
• Evaluate the impact of process, tooling, equipment, or material changes on validated states and product quality.
• Participate in internal, customer, and regulatory audits as a technical subject matter expert.

New Product Introduction (NPI)

• Support new product introduction activities from design transfer through production launch.
• Participate in design reviews and manufacturability assessments to ensure robust and capable manufacturing processes.
• Define manufacturing process requirements, equipment needs, tooling considerations, and validation strategies early in development.
• Collaborate cross‑functionally to identify and mitigate manufacturing and process risks to support successful product launches.

Continuous Improvement

• Lead and support continuous improvement initiatives focused on:
  • Scrap and defect reduction
  • Yield improvement
  • Process capability enhancement (Cp/Cpk)
  • Cycle time optimization
  • Downtime reduction
• Utilize Lean Manufacturing, Six Sigma, DMAIC, 8D, and other structured problem‑solving methodologies to improve operational and quality performance.
• Drive corrective and preventive actions that address true root causes and support sustainable process improvements.

Cross‑Functional Collaboration & Training
