Job summary

Spyrosoft Ltd seeks an expert to validate and automate Wi‑Fi, networking, security, and tunneling features across Android and embedded environments. You will test connectivity, authentication, routing, and support automated validation within CI/CD pipelines. On-site presence and occasional client travel are required.

The role emphasizes hands-on testing, fault injection, and collaboration with Android and embedded teams to ensure robust networking solutions.

Qualifications

• Strong knowledge of TCP/IP, DHCP, DNS, NAT, routing, VLANs, and firewalling.
• Solid understanding of WLAN technologies, including 802.11, WPA2/WPA3, EAP (PEAP/TLS/TTLS), and PSK/Open authentication.
• Hands-on experience with network fault injection using tools such as tc, netem, and scapy.
• Experience with packet-level troubleshooting and analysis using Wireshark and tcpdump.
• Strong understanding of the Android Wi-Fi stack, including ConnectionManager, NetworkStack, and wpa_supplicant.
• Experience using ADB for network testing, device connectivity validation, scanning, and log collection.
• Ability to analyze Android logcat data and correlate Wi-Fi, EAP, and TLS behavior with access point logs.
• Practical experience with Python-based test automation and Robot Framework.
• Linux system administration and shell scripting skills.
• Experience with Git workflows, CI/CD integration, Jira, and Confluence.

Responsibilities

• 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.
