Job summary

Ciena Corporation is seeking a hands-on Transmitter SerDes Design Lead to design and deliver high-speed transmitter macros for 224G and 448G SerDes in deep-submicron CMOS technologies. You will own schematic-level design, post-layout verification, and collaboration with cross-functional teams to meet product requirements.

The role requires 10+ years in high-speed analog/mixed-signal transmitter design, experience with DAC-based output stages, serializers, and clocking circuits, and proficiency

Qualifications

• Bachelor's degree required in Electrical Engineering or Computer Engineering
• 10+ years of industrial experience in high-speed analog, mixed-signal or SerDes transmitter circuits
• Experience from schematic design through post-layout verification
• Experience applying transmitter blocks (DAC output, serializers, output drivers, clocking circuits)
• Ability to perform post-layout simulations and validate performance across PVT
• Proven ability to deliver analog circuit designs through silicon validation

Responsibilities

• Own schematic-level design and post-layout verification of transmitter chain blocks (DAC output stage, serialization, clocking, output driver)
• Collaborate with management, system designers, and lab validation to evolve architecture and meet requirements
• Evaluate circuit topologies, tradeoffs on power, area, bandwidth, and tech constraints
• Work with layout/design engineers to deliver designs through full GDSII integration
• Drive extraction-based post-layout simulations and validate performance across PVT
• Lead root-cause analysis of gaps and implement corrective actions
• Maintain performance and power tracking against targets
• Translate system requirements into transmitter implementation and share learnings
• Build/use behavioral models (MATLAB, Verilog-A) to support tradeoffs
• Partner with lab teams to correlate silicon results and support bring-up
• Provide technical guidance and mentorship to junior engineers
