About the job
Leads hands-on verification, characterization, modeling, and debug of high-speed electro-optic links across silicon and system programs.
What you'll do
- Characterize and debug high-speed electrical/optical hardware; measure eye diagrams, BER, jitter, equalization, and channel impairments.
- Develop system-level channel models, link budgets, and verification methods, correlating models with bench measurements.
- Support silicon bring-up and root-cause investigations, guide architecture tradeoffs, mentor engineers, and build characterization automation.
What they ask for
- Ownership of verification strategy for a full silicon/system program.
- Deep expertise in 56G/112G/224G+ serial links, SerDes equalization, and signal integrity.
- Hands-on lab experience leading difficult investigations; track record mentoring engineers.
- Strong Python/MATLAB skills and proficiency with VNA, scopes, BERTs, TDRs, and tools such as ADS, HFSS, Cadence, or COMSOL.
Nice to have
- Silicon photonics/EO systems at the architecture level; package/PCB/channel co-design ownership.
- COM/IBIS-AMI modeling or patents/standards contributions (OIF, IEEE 802.3).
