High-Speed Digital Design Engineer
About The Position
viaPhoton is seeking a High-Speed Digital Design Engineer to advance development of 200G+ systems and interfaces for next-generation NPO and Co-Packaged Optics (CPO) products. The role owns the high-speed electrical data path from concept through production and involves hands-on signal and power integrity work for AI data center connectivity. The engineer will guide and mentor junior design team members. Responsibilities include advancing 224G/448G PAM4 signal and power integrity, selecting technology and defining architecture, developing and integrating CPO solutions, and bringing products to production. The role also involves defining PCB materials and stack-ups; evaluating S-parameters, eye diagrams, crosstalk, jitter, and COM performance; and assessing host and optical technologies, compute fabrics, and scale-up/scale-out topologies. The position is onsite in Naperville, Illinois, Monday through Friday. Compensation is $80,000–$150,000 base salary, plus an annual bonus.
Requirements
- Bachelor of Science in Electrical Engineering.
- At least 3 years of hands-on high-speed design experience.
- Background in high-speed transceiver or transponder development, ideally for 200G/PAM4+ interconnect.
- Experience designing and applying 224G/448G PAM4 or PAM6 interconnect and related OIF-CEI or IEEE standards.
- Knowledge of high-speed signaling fundamentals, channel behavior, PCB technologies, and RF design techniques.
- Comfort with SI simulation tools such as ADS or HFSS, and with EMI/EMC evaluation and mitigation.
Responsibilities
- Advance development of 200G+ systems and interfaces for NPO and CPO products, including 224G/448G PAM4 signal and power integrity.
