Coherent RF Architect – Job DescriptionWe 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 LearnKey ResponsibilitiesSilicon Bring‑up & DebugOwn 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‑positive procedures to accelerate lab triage and cross‑team communication.Full AFE Characterization (Bench + Automation)DAC: SFDR, IMD, THD, SNR, ENOB, spurs vs. output amplitude, output frequency, sampling frequency, temperature, supply, and code format; static linearity where applicable.ADC: SNR, ENOB, SFDR, interleaving mismatch (offset/gain/timing), harmonic/spurious behavior, clock sensitivity.PLL/Clocking: phase noise, integrated jitter, spur analysis, jitter
