Telecom & Modem Engineer (Senior/Staff)

About the role

You will be building the system that modem and Wi-Fi engineers at device makers rely on to get from a trace to a root cause. You'll build the first system that does automatic cross-layer root cause from the baseband, through QMI and the radio HAL, into Android, grounded in the customer's own stack.

What you'll do

• Build parsers and analysis for modem traces: DIAG, QMI, QXDM/QCAT, modem ramdumps and crash logs
• Build parsers and analysis for AP/CPE diagnostics: wlan driver and firmware logs, hostapd/wpa_supplicant logs, syslog, and packet captures
• Map observed failures to root cause across NAS, RRC, and L1/L2, and across the RIL / radio HAL interface into Android
• Implement Wi-Fi-stack reasoning: association/auth flows, roaming, mesh (EasyMesh), throughput and interference triage, driver/firmware crash analysis
• Encode the cellular- and Wi-Fi-stack reasoning the platform uses to ground remediations
