Senior/Staff Quality Assurance Engineer or Manager (OSAT)

About the role

This role covers quality management for semiconductor assembly and test processes in an OSAT environment. It involves maintaining quality standards, driving root cause analysis and corrective actions, monitoring process capability, supporting supplier and customer quality, and conducting audits.

Key responsibilities

• Design, monitor and maintain quality standards for semiconductor assembly and test, and develop quality documentation such as Control Plans, PFMEA, process flow charts, incoming and outgoing quality requirements and work instructions.
• Ensure compliance with customer, industry and internal quality requirements, as well as relevant ISO standards such as ISO 9001.
• Lead root cause analysis using 8D, 3x5 Why, Fishbone and other tools, and drive CAPA for quality excursions and customer complaints.
• Support failure analysis and coordinate with engineering teams on resolution.
• Monitor process capability using SPC, analyse yield, defect trends and reliability data, and lead continuous improvement projects to reduce defects and improve yield.
• Support supplier audits and qualification, interface with OSAT partners, customers and internal stakeholders on quality issues, and manage change control requests for materials, processes and equipment.
• Conduct internal and external quality audits and support customer audits and certification; ensure compliance with QMS, ISO 9001, IATF 16949, JEDEC and customer requirements.
