Coherent Systems Architect - Mixed Signal AFE development

Coherent RF Architect – Job Description

We are seeking a hands‑on Coherent RF Architect to lead silicon bring‑up, validation, and production test development for a mixed‑signal Analog Front‑End (AFE) featuring high‑speed DACs, ADCs, PLL/clocking, and the RF electrical interface to the Transmitter and Receiver Optical Sub‑Assembly (TROSA) used in the optical coherent pluggable. The role owns end‑to‑end AFE characterization, from bench measurement and automation through correlation to simulation test coverage.

How You Will Contribute And What You Will Learn

Key Responsibilities

• Silicon Bring‑up & Debug
  • Own first‑silicon bring‑up for DAC/ADC/PLL blocks: power‑up sequencing, register access, clock tree bring‑up, and initial functional validation.
  • Debug mixed‑signal issues across domains (clocking, analog biasing, digital control, interfaces, and test modes).
  • Create debug playbooks and known‑good procedure...
