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.
