Senior​/Principal Engineer - Test Engineering

Build the future nobody's dreamed of yet... are you ready to rethink the impossible? Develop, debug, and maintain A93K test programs in SmarTest7, including test methods, levels, timing, specifications, equations, limits, and test flows. Create modular test methods and measurement algorithms using C++, implementing data processing and limit-validation routines. Lead silicon bring-up, characterization, bench-to-ATE correlation, production release, test coverage improvement, robustness enhancement, and test-time reduction.

Design and validate mixed-signal load boards; troubleshoot hardware/software issues using oscilloscopes, spectrum analyzers, and ATE diagnostics. Implement multi-site and parallel-test strategies to increase high-volume manufacturing throughput. Analyze characterization and production data to identify yield and quality opportunities; automate engineering workflows and generate correlation, yield, and customer-facing test reports. Collaborate with Design Engineering on test requirements and DFT, with Product Engineering on manufacturing optimization, and with Applications/Marketing on product evaluations.

Bachelor's degree in Electrical, Electronics, or Computer Engineering, or a related discipline. At least 3 years of experience in semiconductor test development, with strong hands‑on knowledge of Advantest
93000 and Smar Test. Proficiency in Java, C++, or another object-oriented language, plus familiarity with software version control. Solid semiconductor measurement knowledge and mixed‑signal experience with ADCs, DACs, MEMS sensors, and digital communication interfaces. Working knowledge of sampling theory, Nyquist criteria, FFT/DFT, FIR/IIR filtering, SNR, THD, and frequency response analysis. Strong communication and collaboration skills, with a sense of ownership for the product.

A drive for independent learning High-volume manufacturing experience. Testing of MEMS sensors, silicon microphones, audio products, or mixed‑signal ICs. Experience using data analysis tools to perform data exploration, statistical analysis, process optimization, and data-driven decision-making. Mandarin capability is an added advantage for collaboration with manufacturing partners in China.
