Job description

Job 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.

Requirements

• Core Protocol Knowledge: Deep understanding of IEEE 802.11 standards (802.11n/ac/ax and emerging 802.11be), including frame formats, state machines, channel access mechanisms (CSMA/CA, EDCA), and security standards (WPA2/WPA3 Personal and Enterprise).
• Hands-on Lab Instrumentation: Proficiency in operating RF test equipment:

Job Responsibilities

• Vector Signal Analyzers (VSA) and Vector Signal Generators (VSG)
• Spectrum analyzers, power meters, and digital oscilloscopes
• Dedicated Wi-Fi test solutions (e.g., OctoScope/Spirent, LitePoint IQxel, Keysight, Rohde & Schwarz)
• RF attenuation matrix switches and programmable faders
• Bachelor's or Master's degree in Computer Science, Computer or Electrical Engineering, Mathematics, or a related field.
