Senior Software Test Engineer

Hands-on Senior Software Test Engineer responsible for test architecture, automation, device characterization, system integration, data analysis, and debugging across SLT, Burn-In, HPC, and semiconductor manufacturing test platforms. The role works directly across semiconductor testers, automated handlers, hardware, firmware, software, instrumentation, thermal systems, test programs, and manufacturing environments.

• Design, develop, and maintain automated test solutions for semiconductor devices and SLT, Burn-In, HPC, and manufacturing platforms.
• Develop test programs, automation, scripts, and tools using Python, C#, C++, or similar languages.
• Define test methodologies, validation plans, acceptance criteria, and production test requirements.
• Perform electrical, thermal, functional, and device characterization.
• Correlate test results across ATE, SLT, Burn-In, validation, and manufacturing environments.
• Develop automated data collection, analysis, reporting, and yield-monitoring solutions.
• Analyze test data to identify yield excursions, device behavior, performance trends, and root causes.
• Define test infrastructure, instrumentation, and system requirements for new products and platforms.
• Debug hardware and system issues using oscilloscopes, logic analyzers, protocol analyzers, and other lab equipment.
• Work closely with hardware, software, firmware, thermal, product, and manufacturing engineering teams.
• Support new product introduction, manufacturing readiness, customer integration, and production ramp.
• All other duties as assigned.

• S. in Electrical Engineering, Computer Engineering, Computer Science, or related technical field.
• 5+ years of experience in semiconductor test, validation, product engineering, or related fields.
• Hands-on experience with SLT, Burn-In, ATE, semiconductor validation, or manufacturing test systems.
• Experience developing automated test software using Python, C#, C++, or similar languages.
• Strong understanding of digital and analog circuit fundamentals, schematics, instrumentation, and board-level debugging.
• Experience with communication interfaces such as SPI, I2C, UART, USB, Ethernet, and PCIe.
• Experience with statistical analysis, yield analysis, test correlation, and large test datasets.
• Must be willing to work onsite in our Lake Forest, CA office.

• Experience with semiconductor SLT, Burn-In, HPC, or ATE platforms.
• Experience with automated characterization and high-volume manufacturing test.
• Experience correlating device performance across multiple test platforms and environments.
• Experience with test-data analytics, dashboards, and automated reporting.

• Willingness to work in an on-prem and on-site setup (No Hybrid) in Lake Forest, CA.
• Ability and willingness to travel domestically and internationally, sometimes on short notice.
• Strong written and verbal communication skills.
