Automated Test Engineer

Job Title

Role Overview

Responsibilities

• Develop, maintain, and extend software and proprietary scripting language for custom ATE platforms
• test sequencer, instrument control, safety and interlocks, logging, and UI as needed
• Design and implement automated test flows for wafer‑level and die-level uLED transceiver devices, including LIV (light–current–voltage) characterization, photodiode responsivity, parametric tests, and reliability screens
• Debug test failures across the full stack: probe card electronics, load/probe boards, cabling, instrumentation, and ATE software
• Work closely with probe card and hardware engineers to bring up new probe card designs, define pin‑maps, verify connectivity, and validate signal integrity on test stations
• Integrate new instruments and subsystems into the ATE (SMUs, oscilloscopes, light measurement instruments, motion stages, etc.), including driver development and calibration routines
• Build robust data pipelines for LIV and parametric measurements: automated collection, storage, and post‑processing (yield analysis, trend analysis, outlier detection, correlation with design/process data)
• Create dashboards and reports for engineering and operations, including automated daily/lot‑level summaries and failure analysis
• Support new product introduction on the tester: first silicon/first build bring‑up, characterization plan execution, and transition to production flows
• Drive root‑cause analysis for test escapes, yield excursions, and systemic failures, and implement corrective actions in test code, hardware, or documentation
• Write and maintain technical documentation: test specifications, software design notes, ATE configuration baselines, and troubleshooting guides for operations
• Provide hands‑on support to production and lab technicians for ATE usage, including training and on‑call support for critical issues

Required Qualifications

• BS or MS in Electrical Engineering, Computer Engineering, or related field
• 1–4 years of experience in semiconductor test engineering, ATE development, or similar automated test roles (wafer sort, final test, or system‑level test)
• Strong proficiency in Python
• Demonstrated ability to debug hardware‑software interactions: understanding schematics, probing boards, and correlating electrical issues with software behavior
• Experience with basic semiconductor test methodologies: parametric testing, functional testing, and characterization; familiarity with concepts like test coverage, guardbanding, and yield
• Strong data analysis skills (e.g., using Python, Pandas, or similar tools) for large test datasets, including statistical analysis and visualization
• Working knowledge of common lab equipment (SMUs, oscilloscopes, power supplies, DAQ, signal generators) and their remote‑control interfaces
• Excellent communication and documentation skills, with a track record of writing clear test specs and debug notes

Preferred Qualifications

• Experience with wafer‑level probe test, including probe cards, prober integration, and chuck/motion control
• Background in LED, laser diode, or optoelectronic device testing; familiarity with LIV curves, optical power measurement, and related metrics
• Familiarity with data infrastructure for test: SQL or time‑series databases and dashboarding tools
• Knowledge of version control (Git) and modern software development practices (code reviews, CI for test software)
• Exposure to reliability and qualification testing (HTOL, temperature cycling, etc.) and how these integrate with production test flows
• Experience working with cross‑functional teams (design, process, packaging, operations, and product engineering) to define and refine test requirements
