• Build automated functional, regression, and interoperability tests.

• Maintain AI agent skills related to test automation and integration.

• Automate validation of RAN Intelligence apps (xApps, rApps).

• Support the integration of the platform with third-party components.

• Document scenarios, tools, and test procedures to support internal demos, partner trials, and training.

Pre-Requisites / Skills / Experience Requirements:

• Experience with agentic testing, AI-assisted coding and documentation.

• Master’s degree in Telecommunications Engineering, Wireless or Mobile Communications, or a related field. A bachelor’s degree with strong relevant experience will also be considered.

• Understanding of mobile networks (LTE, 5G, RAN, KPIs); knowledge of O-RAN is a plus.

• Good Python programming skills.

• Familiarity with Linux, Docker and Git.
