 * Experience with Open RAN (O-RAN) architectures and interfaces.

## Description

Qualcomm's Wireless R&D group develops the Test Base Station (TBS), a platform used to verify the functionality of QCT mobile chipsets. In this role, you will define, develop, and execute protocol test plans that validate next-generation cellular technologies. You will work closely with development teams to debug complex protocol stack issues, ensure compliance with 3GPP standards (Release 15 through 18 and beyond), and help build the foundation for 6G wireless protocols., * Test design and execution : Create, update, and execute comprehensive test plans for 5G NR (Standalone and Non-Standalone) and early 6G protocol layers (L1/L2/L3).

 * Protocol analysis : Analyze air interface logs and debug complex signaling across the NAS, RRC, PDCP, RLC, and MAC layers.
 * Test automation : Design and maintain Python test scripts that improve test coverage and execution efficiency.
 * Collaboration : Work with software developers, system architects, and field engineers to reproduce, isolate, and resolve critical defects.
 * Standards alignment : Track evolving 3GPP standards and turn new feature requirements into actionable test cases.
 * Documentation : Write detailed test plans, procedures, and reports that track validation progress and coverage.
