Staff Test Operations Engineer

Job Title

Staff Test Operations Engineer

Role Summary

Provide Test Operations and engineering support for products after manufacturing release. Drive operational improvements—OEE, yield, cycle time, and cost reductions—across internal factories and outsourced test suppliers in APAC.

Report to Test Operations within the Operations Engineering Department and coordinate with Product Groups, Supply Chain, Quality, Packaging, Foundry and PMO.

Experience Level

Senior-level. Preferably more than 5 years' experience in high-volume semiconductor test manufacturing.

Responsibilities

Execute and coordinate test operations activities and improvements across sites and suppliers.

• Interface test operations with product groups and cross-functional teams across US, Japan, India, Malaysia and China.
• Manage daily test operations with internal factories and OSATs: lot tracking, dispositions, test program releases, hardware troubleshooting/repairs.
• Monitor and improve equipment uptime, tester utilization and OEE.
• Coordinate probe/final test transfers from NPI to high-volume manufacturing.
• Plan and execute new test capacity and technology deployments (tester, handler, hardware).
• Implement test best practices and process standards at manufacturing sites.
• Drive gross margin improvements via OEE, yield and retest reduction initiatives.

Requirements

Must-have technical skills and experience for the role.

• 5+ years in high-volume semiconductor test manufacturing (probe/WLCSP and final test) preferred.
• Hands-on experience with major ATE tester platforms (e.g. Teradyne UltraFLEX/Flex, Advantest 93K).
• Familiarity with test processes, equipment operations and production planning concepts.
• Strong problem-solving skills (8D, Why-Why analysis) applied to process and manufacturing challenges.
• Good understanding of analog/digital/power product test methodology, failure analysis and reliability testing.
• Strong communication and interpersonal skills for interaction at all levels.
• Strong project management skills to coordinate transfers and capacity expansions.

Nice-to-have:

• Experience managing OSAT test operations.
• Proficiency with WLCSP probing hardware, test probers and map merging.
• Experience with statistical data analysis tools (JMP, Spotfire, etc.).

Education Requirements

Minimum bachelor's degree in Electrical, Electronic, Computing or related engineering discipline.
