Electro-Optic Link Hardware Engineer

Responsibilities:

• Run hands-on lab characterization and debug of high-speed electrical/optical hardware
• Characterize eye diagrams, BER, jitter, equalization, and channel impairments across process/voltage/temperature
• Build and correlate electrical/optical/EO channel models against your own bench measurements
• Execute link budget validation measurements and flag gaps between model and silicon
• Support silicon bring-up and root-cause debug alongside analog, package, PCB, and SerDes teams
• Build automation and scripts (instrument control, data pipelines, analysis) to speed up characterization
• Document measurement setups, methods, and results so others can reproduce them

Qualifications:

• PhD in EE, Photonics, Physics; or MS +3 years of relevant experience
• Hands-on experience characterizing and debugging high-speed serial links (56G/112G+)
• Working knowledge of SerDes equalization (CTLE/FFE/DFE) and signal integrity fundamentals (S-parameters, insertion/return loss, crosstalk)
• Strong bench skills: VNA, real-time and sampling scopes, BERTs, TDRs
• Comfortable building a setup from scratch and knowing when the measurement is lying to you
• Solid Python or MATLAB for instrument automation and data analysis
• Track record of closing out debug investigations at the bench
• Preferred Qualifications:
• Silicon photonics or EO link exposure (modulators, photodetectors, optical test)
• ADS, HFSS, or similar simulation tools
• COM/IBIS-AMI familiarity
• Package/PCB channel measurement or de-embedding experience
• We offer competitive compensation. The base salary range for this role determined based on location, experience, educational background, and market data.
