Modem System Test Engineer - Wireless Technologies and Ecosystems |
Core
End-to-end system testing, performance characterization, and failure triage of advanced cellular baseband and multi-radio coexistence features to ensure seamless concurrent operation between cellular technologies (LTE, 5G NR) and adjacent radios (Wi-Fi, Bluetooth, UWB, GNSS).
Role type
Senior IC modem system test engineer (wireless coexistence)
Builds
Robust real-world performance of multi-radio platforms under hostile interference conditions
Domain
Telecommunications / Wireless / RF / 3GPP
Required skills
3GPP LTE/5G NR protocol stack expertise, RF transceiver architecture knowledge, in-device coexistence (IDC) mitigation techniques, RF instrumentation operation, Python test automation, root-cause analysis of multi-layer failures, lab testbed integration
Preferred skills
Dual-SIM/Dual-Active scenario testing, 3GPP IDC specifications familiarity, non-cellular wireless standards (Wi-Fi 6/6E/7, Bluetooth, UWB, NFC, GNSS), data analysis libraries (Pandas, NumPy, Plotly/Matplotlib), 3GPP standardization contributions
