Role Description Reading modem traces well is rare, which is why this stays a specialist problem. 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. Location: Remote (4h overlap with Pacific or IST; Seattle or Bengaluru on-site preferred). Full-time. Qualifications - 10+ years of relevant engineering experience. - Deep modem or baseband experience: bringup, debug, or protocol-stack work. - Fluency with DIAG/QMI, QXDM/QCAT, and reading modem crash dumps. - Working knowledge of 4G/5G NAS, RRC, and lower-layer behavior. - IMS/VoLTE/VoNR debugging: SIP/IMS signaling and carrier field issues. - Comfort at the RIL / radio HAL boundary. - Proficient in day-to-day work with CLI-based AI coding tools like Claude Code (or an equivalent). Requirements - Build parsers and analysis for modem traces: DIAG, QMI, QXDM/QCAT, modem ramdumps and crash logs. - Map observed failures to root cause across NAS, RRC, and L1/L2, and across the RIL / radio HAL interface into Android. - Encode cellular-stack reasoning the platform uses to ground remediations. Benefits - Qualcomm modem internals. - MediaTek modem familiarity (ELT / MTK logging). - Carrier certification or lab/field debug experience. - Any exposure to log-analysis or ML tooling. - Network-side or RAN familiarity (gNB, RRC, NGAP, CU/DU/RU splits, open-RAN).
