Wi-Fi System Engineer IRC307227
Description Collaborate with Baseband, RF, Antenna, and Software/Firmware teams to define system architectures, throughput targets, and latency budgets. Perform PHY/MAC layer performance trade-off studies (MIMO, beamforming, OFDMA, MU-MIMO, Multi-Link Operation / MLO, AFC) Architect, build, and maintain automated test beds for Wi-Fi performance, interoperability, roaming, and functional compliance. Characterize system throughput, packet error rate (PER), latency, jitter, EVM, and spectral emissions using conducted and over-the-air (OTA) setups. Emulate complex real-world environments using multipath channel emulators, RF matrix switches, anechoic chambers, and attenuation arrays. Develop automated test frameworks and measurement scripts in Python to streamline regression testing and stress tests across diverse client ecosystems. Drive root-cause failure analysis (RCFA) for complex wireless anomalies using sniffer traces (Wireshark/OmniPeek), log parsers, and RF test instruments.
