Senior / Staff Test Engineer

Key Responsibilities

• OSAT Management: Direct and manage wafer sort (CP), final test (FT) and system-level test (SLT) operations at OSAT/subcontractor sites.

• Test Ownership: Own end-to-end test coverage, test flows, and statistical test limits across product lifecycles.

• Cross-Functional Collaboration: Partner closely with Design for Testability (DFT), Product Engineering, Quality, and Manufacturing teams to achieve NPI milestones.

• New Product Introduction (NPI): Lead NPI test execution, including test program validation, platform correlation, hardware bring-up, and production ramp-up.

• Yield & Quality Optimization: Continuously monitor test yields, DPPM, and quality metrics; drive root-cause analysis and implement cost-reduction and test-time-reduction (TTR) initiatives.

• Failure Analysis & Quality Escapes: Lead technical investigations for yield fallouts, test escapes, customer returns, and 8D reporting.

• Change Management: Oversee engineering change orders (ECOs), test program revisions, and product transfers across test sites.

• Hardware & Process Reliability: Ensure all test hardware (probe cards, load boards, sockets) and test procedures conform to quality, budget, and delivery timelines.

Required Qualifications

• Education: Bachelor’s degree in Electrical Engineering, Electronic Engineering, or a related technical discipline.

• Experience: 3-10 years of hands-on and proven experience in semiconductor test engineering, product engineering, or high-volume semiconductor manufacturing environments.

• Technical Knowledge: Strong understanding of wafer sort, final test (FT), and system-level test (SLT) methodologies.

• Hardware Expertise: Practical knowledge of test hardware design and troubleshooting, including probe cards, load boards, sockets, and DUT boards.

• OSAT Exposure: Direct experience interfacing with external OSAT vendors and OSAT manufacturing environments.

• Soft Skills: Strong analytical thinking, problem-solving mindset, attention to detail, and cross-functional communication skills.

Preferred Qualifications

• ATE Platforms: Hands-on experience with modern Automated Test Equipment (ATE) platforms, such as Advantest 93000 (93K) SmartScale PS1600 or ExaScale.

• System-Level Testing (SLT): Hands-on experience troubleshooting SLT hardware/software interactions and board-level issues.

• Programming & Automation: Proficiency in C/C++ (for ATE program development) and Python/Bash (for data parsing and SLT test automation).

• Signal & Power Integrity: Fundamentals of high-speed digital/analog testing, signal integrity, and power integrity design.

• Data & Yield Analysis: Experience with yield analysis tools, STDF data parsing, and Statistical Bin Limiting (SBL/SBC).
