Sr. Photonic/Radio Frequency (RF) R&D Test Engineer

About the role

As a member of the test engineering team, you will design, implement, automate, and execute test solutions to validate the functionality of Silicon Photonics devices and Photonic Integrated Circuits (PIC) at the wafer, die, and package levels. The testing focus includes high-speed electro-optic modulator testing of S parameters up to 100 GHz and eye diagrams with data rates up to 400 Gb/s.

What you'll do

• Develop custom test hardware and automated test software for wafer and die testing on proprietary test stations.
• Design and implement custom test solutions for 100-400 Gb/s optical eye testing at the die and wafer level, executing DVT testing on 1.6T and 3.2T optical transceivers using BERTs, DCAs, VNAs, and AWGs.
• Match experimental data to modulator equivalent circuit models.
• Implement different methods of measuring laser RIN and compare their performance.
• Write and debug test automation scripts in Python, implement and verify analysis equations, and execute tests on designated test stations.
• Perform data analysis in JMP or Python, communicating test plans, results, and project status with internal and external customers.
• Supervise facilities technicians and equipment contractors for ongoing equipment maintenance.

What you'll need

• Advanced degree in Electrical/Optical Engineering or Physics.
• Experience in photonic and high-speed RF testing.
• Programming experience, preferably in Python.
• Demonstrated experience in data acquisition systems, data analysis, and fitting test data to model equations.
• Written and verbal communication skills for technical documentation and reporting.

Skills: wafer test, RF testing, S parameters, BERT, VNA
