We're hiring:
Test Development Engineer
The Test Development Engineer will be responsible for designing, developing, and optimizing test solutions for semiconductor devices, including analog, digital, and mixed-signal products. This role involves creating test programs, defining hardware setups, analyzing device performance, and supporting high-volume production to ensure product quality, reliability, and competitive time‐to‐market.
Key Responsibilities:
Test Development
* Design and implement test programs on ATE (Automatic Test Equipment).
* Develop functional, parametric, and characterization test sequences for new semiconductor devices.
* Create scripts, modules, and software libraries to automate test procedures and data analysis.
Hardware Integration & Debug
* Design, validate, and debug loadboards, probe cards, interposers, adapters, and other test interface hardware .
* Perform electrical debug, root-cause analysis, and troubleshooting on test setups.
* Collaborate with IC design teams to understand device specifications, operating modes, and test requirements.
Characterization & Qualification
* Conduct detailed measurements of electrical parameters, analog/digital performance, or RF characteristics .
* Analyze data using specific software, or internal data systems.
* Prepare technical reports, documentation, and recommendations for test improvements.
Production Support
* Transfer test programs from development to production lines (internal facilities or external test houses).
* Optimize test time, yield, repeatability, and overall cost of test.
* Ensure product quality through yield analysis, test optimization, and SPC (Statistical Process Control).
Requirements
* Bachelor's or Master's degree in Electronics Engineering, Computer Engineering, Telecommunications, or equivalent.
Technical Skills
* Strong understanding of analog/digital circuits and electrical measurement techniques.
* Experience with at least one ATE platform (e.G., Advantest V93K, Teradyne UltraFlex/ETest, NI STS).
* Proficiency in programming languages used in test development: C/C++, Python, LabVIEW, VisualBasic, or ATE‐specific languages.
* Ability to read and interpret electrical schematics, datasheets, and product specifications.
* Familiarity with lab instruments (oscilloscopes, SMUs, signal generators, spectrum analyzers).
Soft Skills
* Strong analytical and problem-solving mindset.
* Ability to work effectively in cross‐functional teams (design, production, quality, R&D).
* Clear communication and technical reporting skills.
* Attention to detail and strong organizational skills.
Preferred Qualifications (Nice-to-Have)
* Experience in post-silicon validation or characterization labs.
* Knowledge of DFT (Design for Testability) techniques and scan methodologies.
* Understanding of statistical analysis (CPK, Gage R&R, DOE).
* Experience working with high-volume semiconductor manufacturing .
