Key Responsibilities:

Site & Partner Management

• Serve as Hyperlight's site manager for all test and OSAT activities in Taiwan.
• Lead and manage a team that acts as Hyperlight's primary on-site interface with external manufacturing partners, including foundry test teams and OSAT vendors, to ensure seamless production execution.
• Work with manufacturing partners and equipment vendors to debug test-related hardware and software issues, minimizing downtime and disruption to production.

Production Execution

• Own and drive wafer-level backend execution across foundry and OSAT partners — including dicing/singulation, bumping, and assembly — covering prioritization, scheduling, vendor readiness, and day-to-day execution to meet production timelines and delivery commitments.
• Partner with operations teams to optimize wafer flow from foundry to OSAT, ensuring smooth logistics and minimal delays.
• Ensure the integrity, accuracy, and organization of data received from foundries and OSATs to support effective analysis and decision-making.

Yield, Quality & Test Optimization

• Collaborate with test engineering, process engineering, operations, and quality teams to troubleshoot backend process yield and test-related issues.
• Work with Hyperlight test engineering teams to reduce production test time while maintaining coverage and product quality.
• Coordinate with internal stakeholders and external partners to identify root causes and drive timely resolution of yield excursions and test anomalies.
• Oversee implementation of corrective actions at foundry test and OSAT sites, and track effectiveness through yield and test metrics.

Requirements

Education

• Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, Materials Science, Photonics, or a related technical discipline.

Experience

• 10+ years of experience in semiconductor test, product engineering, or manufacturing operations, including at least 2 years in a management role, with direct engagement with foundries and OSAT partners.
• Proven track record managing OSAT operations end-to-end — production scheduling, execution, yield tracking, and vendor performance management.
• Demonstrated impact reducing cost-of-test and optimizing test time, with measurable improvements in production efficiency.

Continuous Improvement & Communication

• Drive continuous improvement initiatives for production workflows, focusing on efficiency, quality, and cycle time reduction.
• Establish and maintain clear communication and reporting formats on production status, issues, and improvement initiatives for internal and external stakeholders.
• Experience leading root cause analysis and driving corrective actions to closure across external partners, using a data-driven approach.
• Experience leading cross-functional initiatives across test engineering, process, operations, and external vendors, with the ability to influence without direct authority.

Technical Expertise: Deep knowledge of semiconductor backend (post-fab) manufacturing, including:

• Wafer sort / probe (wafer test)
• Wafer-level dicing/singulation — street layout awareness, saw/laser process fundamentals, tape/film selection, kerf/edge quality control, and dicing-to-pick handling
• Wafer bumping (e.g., Cu pillar / solder bump) — process flow (UBM/metallization, plating, reflow), bump metrology, reliability risks, and supplier control plans
• Die/chiplet assembly and packaging — die attach, pick-and-place/flip-chip, underfill/encapsulation, substrate/interposer considerations, and in-process quality checks through final test readiness
• Expertise in optical testing — characterization, validation, and troubleshooting of photonic or optical devices — is a plus

Skills & Attributes

• Excellent communication and stakeholder management skills, with experience presenting data, issues, and recommendations to both technical and executive audiences.
• Proficiency in written and spoken English and Chinese.
• Self-directed and results-oriented, with strong ownership and accountability in a fast-paced, high-ambiguity environment.

Benefits

• Competitive market-based compensation and benefits
• Professional growth and mentorship opportunities
