Project Description:

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.

Additional Project Requirements:

• The project involves working with hardware prototypes located in the office; therefore, occasional on-site presence will be required.

• Occasional travel to the client's site in Berlin may be required as part of project activities.

Scope of Services:

• 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.
