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 .
