Job Summary:

We are seeking a highly technical Wireless System Validation Engineer to drive the qualification and optimization of our next-generation cellular products. In this role, you will be responsible for the end-to-end validation of cellular modem performance, focusing on 5G NR (SA/NSA) and LTE-A technologies. You will bridge the gap between wireless HW development and system-level deployment, by understanding compliance with 3GPP standards and carrier requirements while maintaining industry-leading performance in power, sensitivity, and throughput.

Key Responsibilities:

-Test Strategy & Execution: Define, develop, and execute comprehensive test plans for cellular modem validation across various radio access technologies (5G NR FR1/FR2, LTE-A, UMTS).

-Protocol Stack Analysis: Perform deep-dive log analysis of the cellular protocol stack (L1, MAC, RLC, RRC, and NAS layers) to identify and root-cause signaling failures, handovers, and throughput drops.

-System Performance Benchmarking: Characterize key performance indicators (KPIs) such as RSRP, SINR, BLER, and Peak Throughput under varying network conditions (fading, interference, and mobility).

-Test Automation: Design and maintain scalable automation frameworks using Python to increase test coverage and efficiency in lab and regression environments.

-Failure Analysis & Debugging: Collaborate with Firmware, Hardware, and System teams to debug complex system-level issues.

-Lab Management: Operate and configure high-end cellular network emulators and RF test equipment for both signaling and non-signaling test modes. Tools & Software Environment
