DSP SW Engineer

You will work closely with the Analog and Mixed-Signal (AMS) and Digital IC design teams to

contribute to system architecture, partition analog and digital implementations, model channels,

and support IC design, verification, and characterization.

Your key responsibilities will include

:• Channel Modeling: Model optoelectronic components (e.g., laser drivers, Transimpedanc

eAmplifiers (TIA)), photonics (e.g., VCSEL, PIN photodiodes), and optical transmission effect

s(e.g., chromatic dispersion (CD), effective modal bandwidth (EMB), modal noise (MN), an

dmode partition noise (MPN)), understanding their impact on signal distortion, both linear an

dnon-linear, noise and jitter

.• Algorithm Development: Invent, simulate, and validate energy-efficient DSP algorithms i

nboth floating-point and fixed-point precision. These algorithms will be used for adaptive AM

Sblocks calibration, adaptive channel equalization, timing recovery, symbol synchronization

,FEC encoding/decoding, and signal quality assessment for both electrical and optical physica

llayers

.• Hardware Testing & Optimization: Measure and optimize algorithms on actual hardware

,correlating models and performance with prior simulations. You will refine models and updat

esimulation environments to ensure alignment with experimental data
