Your tasks

The project focuses on validation and automation of Wi-Fi connectivity, networking, security, and tunneling features across Android and embedded environments. The role involves testing network reliability, authentication mechanisms, routing behavior, and connectivity scenarios while supporting automated validation frameworks and continuous integration processes.

• Develop and maintain automated test suites covering Wi-Fi, DHCP, VLAN, routing, tunneling, and security scenarios.
• Design and execute fault injection tests, including network interruptions, packet loss, DHCP conflicts, and TLS failures.
• Configure and maintain OpenWrt-based routers and embedded test environments.
• Perform Android Wi-Fi testing, including connection flows, WPA3/EAP validation, and log analysis.
• Capture, analyze, and validate network traffic using Wireshark and tcpdump.
• Develop and extend automation solutions using Python and Robot Framework.
• Integrate automated testing outcomes into GitLab and Jenkins CI/CD pipelines.
• Collaborate closely with Android developers, embedded engineers, and verification teams.
• Document test cases, execution results, and findings in Confluence and Jira.
