• Support production ramp‑ups, engineering changes, and sustaining manufacturing activities.
• Partner with Operations and Production teams to resolve assembly issues and improve manufacturability.

Quality Engineering & Problem Solving

• Lead or support root cause investigations for manufacturing quality issues, nonconformances, and customer‑reported defects.
• Implement corrective and preventive actions that address true root cause and drive long‑term process stability.
• Apply risk‑based quality tools such as PFMEA and control strategies as part of process ownership.
• Participate in MRB (Material Review Board) activities, supporting data‑driven disposition and corrective actions.

Supplier Quality Support 

• Support the resolution of supplier‑related quality issues impacting manufacturing.
• Coordinate containment, investigation, and corrective actions for incoming or in‑process supplier nonconformances.
• Communicate effectively with suppliers and internal stakeholders on technical and quality topics.
• Provide manufacturing and quality feedback to support supplier performance improvement.

Quality Systems & Process Discipline

• Support execution and continuous improvement of the site’s quality management system.
• Ensure inspection methods, measurement practices, and calibration requirements are implemented and sustained.
• Support internal audits and corrective action follow‑up in alignment with global quality standards.

Cross‑Site & Cross‑Functional Collaboration

• Work closely with Operations, Production, Engineering, and Quality teams at the Taiwan site.
• Maintain strong collaboration with Manufacturing Engineering and Quality teams in Middlefield headquarters.
• Communicate clearly and effectively across sites, cultures, and time zones.

Key Requirements

• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Quality Engineering, or a related discipline.
• 3–8 years of experience in manufacturing engineering, quality engineering, or a hybrid role within a manufacturing environment.
• Hands‑on experience supporting mechanical assembly processes, preferably for precision or complex equipment.
• Strong problem‑solving skills, including root cause analysis and corrective action implementation.
• Ability to read and interpret engineering drawings and technical documentation.
• Fluent English communication skills (written and verbal).
• Comfort working in a global, matrixed organization with cross‑site collaboration.

Preferred Qualifications

• Experience with precision optics, optical instrumentation, or opto‑mechanical assemblies.
• Exposure to supplier quality or supplier engineering activities.
• Working knowledge of PFMEA, SPC, Lean, or Six Sigma tools.
• Familiarity with ISO 9001 or similar quality management systems.
• Experience supporting global manufacturing operations or distributed supply chains.

Bring your manufacturing and quality expertise to Zygo, where precision, collaboration, and continuous improvement define how we work. Join a global team that values hands‑on engineering, practical problem‑solving, and building products that inspire confidence in our customers.
