Role summary
We are seeking a Sr. Engineer for Silicon Validation to own the bringup and characterization of optical chiplets. This role involves executing post-silicon validation across SerDes, photonic, and mixed-signal blocks, developing test infrastructure and automation, and troubleshooting silicon anomalies. You will utilize lab equipment for high-speed characterization, write Python test scripts, and collaborate with cross-functional teams. A Bachelor's degree in Electrical Engineering with 3+ years of experience in post-silicon validation of high-speed or mixed-signal devices is required. Proficiency in SerDes operation, Python, lab equipment, and version control is essential.
Sr Engineer: Silicon Validation
In this role, you will own the silicon bringup and validation of our optical chiplets. You will execute post-silicon bringup and characterization across SerDes, photonic, and mixed-signal blocks, building the test infrastructure and automation that ensures our products meet and exceed specification before customer deployment.
Essential Functions:
-
Perform initial power-on and bringup of new silicon tape-outs, including boot sequence validation, clock/power domain verification, and initial functionality tests.
-
Perform functional and electrical characterization of high-speed SerDes interfaces, photonic control blocks, and mixed signal blocks. Define and execute test plans at both block and chip level.
-
Use lab test equipment (BERT, oscilloscope/DCA, OSA, signal generators) to characterize signal integrity, eye diagrams, BER, jitter, and optical performance metrics.
-
Develop and maintain Python-based test scripts and automation frameworks for regression and characterization testing.
-
Systematically investigate silicon anomalies and failures; collaborate with design and firmware engineers to develop and verify fixes.
-
Write clear test plans, validation reports, and signoff documentation; communicate findings to cross-functional teams.
-
Partner with firmware, analog/mixed-signal, digital, and systems engineering teams across the full product development cycle.
Basic Qualifications:
-
Bachelor's degree in Electrical Engineering or related field with 3+ years of relevant industry experience.
-
Hands-on experience with post-silicon bringup and validation of high-speed SoC or mixed-signal devices.
-
Working knowledge of SerDes PHY operation and characterization, including NRZ and/or PAM-4 signaling.
-
Proficiency with lab equipment used for high-speed characterization: BERT, oscilloscopes, signal analyzers.
-
Proficiency in Python for test scripting and data analysis.
-
Strong troubleshooting skills and ability to work independently in a lab environment.
-
Proficiency with version control (Git) and software development environments.
Preferred Qualifications:
-
Experience with photonic device or electro-optic system characterization and validation.
-
Familiarity with optical measurement equipment (OSA, optical power meters, lasers).
-
Experience with high-speed serial standards: Ethernet (100G+), PCIe, OIF CEI.
-
Experience with board-level debug and hardware bring-up using JTAG or I2C/SPI interfaces.
