• Provide manufacturing expertise during design reviews and product development.

• Partner with Design Engineering, Applications Engineering, and Operations teams to ensure manufacturability.

• Develop process validation plans and qualification criteria for new products.

• Support prototype builds, pilot runs, and production ramp activities.

Global Operations Collaboration

• Partner closely with AIS's Taiwan assembly operations to establish common process standards and best practices.

• Drive cross-site process harmonization and knowledge transfer.

• Participate in global manufacturing reviews and continuous improvement initiatives.

• Support benchmarking and replication of successful process improvements across AIS assembly locations.

Equipment & Technology Leadership

• Define equipment requirements and process technology roadmaps.

• Support selection, installation, qualification, and optimization of SMT manufacturing equipment.

• Collaborate with Maintenance and Equipment Engineering teams to maximize uptime and process capability.

• Evaluate emerging SMT technologies and automation opportunities.

Quality & Compliance

• Ensure compliance with IPC standards and customer-specific manufacturing requirements.

• Support customer audits, internal audits, and corrective action activities.

• Lead PFMEA, Control Plan, and process validation activities.

• Drive a culture of operational excellence and continuous quality improvement.

Leadership & Mentoring

• Provide technical leadership to manufacturing engineers, technicians, and production personnel.

• Develop standardized work instructions, process documentation, and training materials.

• Mentor junior engineers and help build AIS's long-term manufacturing capabilities.
