About the role

Senior Analog & Mixed-Signal Engineer at Ciena driving the design and validation of analog subsystems. Working with DSP team on next-gen coherent optical modems.

Responsibilities

Define and review system‑level analog and mixed‑signal functions for coherent optical modems
Develop behavioral models of analog and mixed‑signal blocks using C++ and SystemC
Collaborate closely with analog, digital, DSP, firmware, and lab teams to align models, specifications, and validation plans
Support ASIC lab bring‑up and characterization, correlating silicon and lab data with behavioral models and system simulations
Mentor junior engineers and contribute to best practices in analog behavioral modeling and system‑level validation

Expert‑level understanding of analog and mixed‑signal processing in high‑speed communication systems
Proven experience writing C++ and/or SystemC behavioral models for hardware‑adjacent systems
Solid understanding of key analog impairments, including noise, distortion, non‑linearity, bandwidth limitations, jitter, and phase noise, and their impact on modem‑level performance
Comfortable working in a Linux‑based development environment, using Git and modern collaborative workflows
Post‑graduate degree in Physics or Engineering with a focus on ASIC hardware, communication systems, and/or control systems
