We're looking for dependable, hardworking people who take pride in their work and want to grow with us.

About the Role

You'll advance the development of 200G+ systems and interfaces for our next-generation Co-Packaged Optics (CPO) products, owning the high-speed electrical data path from concept to production. This is deep, hands-on signal and power integrity work at the cutting edge of AI data center connectivity, and you'll guide and mentor junior engineers along the way.

Advance the development of 200G+ systems and interfaces for our NPO and CPO products, including 224G/448G PAM4 signal and power integrity (SIPI)
Own technology selection, architecture, development, integration, and productization of cutting-edge CPO solutions
Define PCB material selection and stack-ups, and evaluate S-parameters, eye diagrams, crosstalk, jitter, and COM performance
Assess host (switch fabric and xPU) and optical technologies, including compute fabrics and scale-up/scale-out topologies
Guide the electrical data path from concept to production, and mentor junior design team members

What You'll Bring

Have a BS in Electrical Engineering and 3+ years of hands-on high-speed design experience
Bring a background in high-speed transceiver or transponder development, ideally for 200G/PAM4+ interconnect
Have experience designing and applying 224G/448G PAM4 or PAM6 interconnect and related OIF-CEI or IEEE standards
Are well-versed in high-speed signaling fundamentals, channel behavior, PCB technologies, and RF design techniques
Are comfortable with SI simulation tools such as ADS or HFSS, and with EMI/EMC evaluation and mitigation
