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.
