Sr. to Lead Test Hardware Engineer

Job Description

We are looking for experienced Test Hardware Engineers, ranging from Senior Engineer to Lead level, to support test hardware development, bring-up, debugging, and correlation activities in a high-volume semiconductor manufacturing environment.

The successful candidate will play a key role in ensuring test hardware reliability, production stability, and yield improvement across wafer sort and final test operations.

Key Responsibilities

1. Test Hardware Bring-up & Qualification

• Support load board and probe card bring-up for new products on the Advantest V93K platform.

• Perform hardware validation, checkout, and debugging during silicon bring-up.

• Conduct GR&R, stability, and repeatability evaluations before production release.

• Collaborate with Test Engineering and Design teams throughout NPI and HVM transitions.

2. Hardware Debug & Failure Analysis

• Troubleshoot production issues related to test hardware, interfaces, and signal integrity.

• Perform bench-to-ATE correlation and root cause analysis using laboratory equipment such as oscilloscopes, DMMs, and thermal tools.

• Identify and resolve issues involving sockets, load boards, pogo pins, probe cards, and contact failures.

• Support RMA investigations, yield excursions, and lot-on-hold analysis.

3. Test Correlation & Production Release

• Perform ATE-to-ATE, ATE-to-bench, and load board-to-load board correlation.

• Prepare correlation reports and define acceptance criteria for production readiness.

• Validate test limits, guard bands, and parametric consistency across multiple test sites.

• Support hardware qualification and release to OSAT and production sites.

4. Production Support & Yield Improvement

• Monitor hardware-related yield performance and drive root cause investigations and corrective actions.

• Analyze failure trends, bin distributions, and contact yield issues.

• Support test time reduction (TTR) and production throughput optimization.

• Work closely with Product Engineering teams to improve yield and production efficiency.

5. Hardware Design & Optimization

• Review load board schematics, PCB layouts, and signal integrity considerations.

• Optimize site configurations, signal integrity, power distribution, and thermal performance.

• Support multi-site scalability and hardware cost optimization.

6. Cross-functional Collaboration

• Work closely with Test Engineering, Product Engineering, Failure Analysis, OSAT, and Manufacturing teams.

• Share technical knowledge and best practices in hardware debugging and correlation.

• For Lead-level candidates, provide technical guidance to junior engineers and drive project execution, risk management, and stakeholder communication.

Requirements

• Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, or a related field.

• 2+ years of experience in semiconductor test engineering or test hardware engineering.

• Hands-on experience with Advantest V93K platforms (SmarTest 7/8).

• Experience in load board and/or probe card bring-up, validation, and debugging.

• Understanding of semiconductor production testing, including wafer sort (WS) and final test (FT).

• Knowledge of silicon bring-up, characterization, test correlation, and hardware troubleshooting.

• Understanding of signal integrity, power delivery, and analog/digital measurements.

• Familiarity with ATE instrumentation such as DPS, AVI, PPMU, and HSIO.

Preferred Qualifications

• Experience supporting high-volume manufacturing (HVM).

• Familiarity with data analysis tools such as JMP, Exensio, or Excel.

• Understanding of test program structure and hardware interactions.

• Exposure to JEDEC / AEC qualification and reliability testing.

• Experience working with global engineering teams and OSAT partners.

• Strong problem-solving, communication, and cross-functional collaboration skills.
