- Lead the Hsinchu Test Engineering team to develop and release wafer probe and final test solutions for Navitas power semiconductor products, including SiC WLBI, KGD.
- Define test engineering strategy, resource planning, milestones, and release criteria to support NPI, transfer, and high-volume manufacturing.
- Drive production buyoff with OSATs and equipment vendors, ensuring test hardware, software, sockets, probe cards, handlers, and documentation are qualified on schedule.
- Provide technical and organizational leadership for troubleshooting yield, stability, accuracy, repeatability, and safety issues in engineering labs and offshore manufacturing sites.
- Lead design reviews for load boards, probe cards, daughter cards, and interface hardware, including schematic capture, PCB layout guidance, and design-for-debug considerations.
- Partner with Product Engineering, Design, Reliability, Quality, and Operations teams to accelerate product qualification, ramp, and manufacturing readiness.
- Establish and drive corrective actions for tester issues, correlation gaps, abnormal failure signatures, customer returns, and field-return analysis.
- Improve tester utilization, throughput, cost of test, and operational efficiency while maintaining product quality, safety, and long-term manufacturability.
- Recruit, mentor, and develop engineers and technicians, while strengthening cross-site communication, execution discipline, and succession planning.
Knowledge, Skills, Abilities, and Other Characteristics (KSAO's)
- Strong experience in power semiconductor test engineering, including wafer probe and final test for GaN, SiC, or related high-voltage / high-current products.
- Solid understanding of production test challenges including high-voltage safety, dynamic behavior, leakage, switching characteristics, thermal effects, and engineering-to-production correlation.
- Proven experience developing and releasing ATE solutions on platforms such as Accotest, Eagle, or equivalent semiconductor test systems.
- Strong programming capability in C, C++, C#, Python, or equivalent languages for production test software, data automation, and engineering analysis.
- Experience with load board / probe card design, schematic review, PCB layout direction, and debug of hardware issues at board and system level.
- Hands-on lab capability with semiconductor analyzers, oscilloscopes, signal generators, power supplies, DMMs, curve tracers, and reliability-related test setups.
- Strong data-analysis skills using JMP, Python, Excel, or equivalent tools to identify yield limiters, instability signatures, and improvement opportunities.
- Demonstrated people and project leadership: planning milestones, driving closure across stakeholders, coaching engineers, influencing without direct authority, and escalating risks with clear recommendations.
- Excellent written and verbal English communication skills, with the ability to present technical conclusions, plans, and decisions to senior management.
Required Qualifications
Basic
