Test Engineer 4

Responsibilities:

• Own all TE activities for assigned NPI programs from first silicon through mass production release — including test program development, characterization, and NPI flow execution
• Work closely with R&D, Product Engineering, and Operations teams to drive NPI milestones through Final Production Release
• Develop and optimize ATE test programs and hardware for production and characterization testing — primarily on the S100 platform
• Design and execute device characterization plans; collect parametric data across process, voltage, and temperature corners to establish test limits and validate test coverage
• Develop T-FMEA for all new NPI programs; identify and document test coverage gaps with full datasheet spec traceability before production release
• Define and implement new test strategies to improve coverage, reduce test time, and improve test hardware architecture for high-volume production
• Implement CP1 functional screening and CP2 full parametric flows including analog trim sequences; coordinate FT trim sequence validation against design team specifications
• Create probe and final test schematics and lead or participate in hardware review meetings; lead probe card and FT fixture bring-up at OSAT from NPI through mass production
• Port and correlate test programs across alternate OSAT platforms; document correlation approach, site-to-site GR&R & Cpk sign-off criteria, and qualification lot results
• Support OTP programming qualification and post-program verify flows; provide first-response ATE technical support for production issues at primary and alternate OSATs
• Identify and drive test time and test cost reductions; document best practices and sustaining procedures for long-term program health

Minimum Qualifications:

• Bachelor’s degree in Electrical, Electronic, Computer Engineering (or equivalent)
• 5+ years of experience in ATE test engineering within the semiconductor industry
• Direct ATE test program development from NPI through mass production on the S100 platform; sustaining-only backgrounds will not meet this requirement
• Ability to interpret hardware schematics, datasheet parameters, and DFT documents
• Strong understanding of analog/mixed-signal test methodology, including trim, characterization, and parametric screening
• Experience designing multi-site test architectures: DUT board design, contact schemes, site-to-site correlation, and parallel test efficiency
• Hands-on probe card and FT fixture bring-up experience
• Excellent problem-solving skills and attention to detail; must be a team player
• Strong written and verbal communication skills; proficiency in English required; Mandarin working proficiency preferred

Desired Qualifications

• Direct experience with MEMS force/capacitive sensing or haptic actuator ATE test
• Expertise in S100 tester platform — test program development and debugging tools; Advantest V93000 (SMT7/SMT8) experience is a plus
• Experience in automotive testing for haptic feedback or force-sensing applications is a plus
• Experience with OTP programming on ATE: charge pump control, VPP sourcing, and post-program retention verification
• Prior work on T-FMEA development and coverage gap analysis of inherited test programs
• Experience with alternate OSAT qualification: correlation lot design, Cpk sign-off, and multi-site validation
• Demonstrated ability to define and implement new test strategies that reduce hardware complexity or test time
• Experience with PCB schematic and layout tools (OrCAD or equivalent)
• Proficiency in scripting or programming for test automation: C/C++, Python, or Java
• Knowledge of DFT, DFM, and 6-sigma principles
