Senior NPI Test Engineer

Job Title

Senior NPI Test Engineer

Role Summary

Lead technical contributor for new product introduction (NPI) test development across mixed-signal, high-speed digital, and RF product lines. The role owns test strategy from early silicon validation through transfer to high-volume manufacturing and drives reusable test IP and methodologies.

Experience Level

Senior-level — typically 8+ years of semiconductor test engineering experience, including 5+ years in mixed-signal/RF test development.

Responsibilities

Key duties include technical leadership, cross-functional NPI support, innovation, and production scaling.

• Develop and implement test strategies for complex mixed-signal SiGe products from concept through production, including devices operating above 200 Gbps.
• Lead development of test methodologies for high-speed SerDes, CDRs, signal conditioning, and high-speed I/O.
• Specify DFT/testability requirements and create reusable test IP, libraries, and frameworks.
• Represent test engineering in architecture reviews, NPI gate meetings, and test readiness reviews.
• Collaborate with IC design, product engineering, and customer quality teams on characterization, correlation, and manufacturability.
• Evaluate and adopt new ATE platforms and measurement techniques; apply AI/ML for yield and test optimization.
• Transfer test solutions to OSATs, monitor KPIs, and drive test cost and cycle-time reduction.
• Mentor junior engineers and maintain test methodology documentation and training materials.

Requirements

Must-have technical skills and experience; concise list of required capabilities.

• 8+ years progressive semiconductor test engineering experience; 5+ years in mixed-signal/RF test development.
• Proven track record leading NPI programs for high-speed communication ICs.
• Expert-level experience with Advantest V93000 (SmarTest 7/8).
• Advanced programming skills in C/C++, Python, and TCL.
• Deep understanding of high-speed signal integrity, jitter analysis, and BER testing.
• Experience with analog/mixed-signal DFT techniques (BIST, scan, boundary scan).
• RF/microwave test experience beyond 40 GHz and familiarity with PCB design tools (Cadence, Altium).
• Strong foundation in statistical process control, quality methodologies, and cross-functional communication.

Nice-to-have:

• Experience with SiGe BiCMOS process testing, automotive qualification (AEC-Q100), 93000 PS modules and Wave Scale RF.
• Wafer-level testing, probe card design, and test data analytics / machine-learning applications.

Education Requirements

Required: Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field. Preferred: Master’s degree or PhD in a relevant engineering discipline.
