ATE Test Engineer – Optical Transceiver Silicon

The role

You will develop and own production test programs for mixed-signal ICs including SerDes, TIAs, modulator drivers, and control silicon. You will manage test content from bench bring-up through OSAT release and production.

What you will do

• Own test program development for assigned devices or blocks.
• Develop, debug, and optimize ATE test programs for mixed-signal and high-speed devices.
• Support test hardware bring-up and review load board and probe card designs.
• Participate in first-silicon bring-up alongside design and validation.
• Correlate ATE results to bench characterization.
• Act as the day-to-day technical contact for programs at OSATs.
• Analyze sort and final test data to find yield limiters and support failure analysis.
• Build reusable test IP, scripts, and data tooling.

Required qualifications

• BS/MS in Electrical Engineering, Computer Engineering, Physics, or a related field.
• 3–5 years developing production test for mixed-signal or high-speed ICs.
• At least one test program taken to production release.
• Hands-on ATE experience on at least one major platform (Advantest 93K or T2000, Teradyne UltraFLEX or J750, Eagle, Chroma, or comparable).
• C/C++ and Python programming on Linux.
• Solid analog and mixed-signal fundamentals.
• Load board and probe card debug, bench instrumentation, and lab troubleshooting.
• Working knowledge of optical systems and networks, optical power and link budgets, and high-speed serial protocols such as Ethernet and PAM4 signaling.
• Statistical fluency for yield and correlation work using JMP, MATLAB, Python/pandas, or equivalent.
• Exposure to OSAT or subcontract test operations.
• Willingness to travel regionally to test sites.
• Willingness to overlap with US and India hours.

Nice to have

• Silicon photonics, optical transceiver, or opto-electrical test background.
• High-speed SerDes test experience.
• DFT familiarity.
• STDF and test data pipelines.
• Experience supporting a product through its first production ramp.
