Full Job Description
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.
