Develop and execute test cases to analyze Ethernet, IP, 4G-LTE, 5G-NR, Wi-Fi, and Bluetooth behavior. Identify root causes of failures and service underperformance. Perform or commission conformance testing to meet regulatory requirements.
• Develop Test Infrastructure - Select, procure, commission, and configure test cases on network emulators and related test equipment supplied by vendors such as Keysight or Rohde & Schwarz. Develop custom test assets, setups, and scripts to enable efficient testing, including scripts using Python and TTCN. Construct and maintain lab infrastructure, from fixed network test harnesses to RF cabling.
• Generate Documentation - Draft and present Test Plans, Design Reviews, Test Readiness Reviews, and Data Reviews. Review and provide feedback on test plans and reports from suppliers.

• Hands-on test experience with PTCRB/GCF test suites and U.S. MNO conformance testing
• Experience with Wi-Fi, Bluetooth Classic/LE protocol and PHY designs, and coexistence between Wi-Fi and Bluetooth
• Experience in regulatory conformance testing (e.g., FCC emission compliance)
• Ability to use network analysis tools (e.g., Wireshark) and analyze network diagnostic monitors (e.g., Qualcomm QXDM logs)
• Experience using ethernet lab equipment (Ixia or Spirent), and IxNetwork or TTworkbench

Bonus Qualifications:

• Systems and networking foundational knowledge (systems architecture, memory hierarchy, storage subsystems, LANs, routing).
• Experience with: IEEE 802.3x Ethernet standards and both NRZ and PAM-4 signaling. CCNA, CCNP, CCIE certifications are a plus. Common bus protocols (SPI, I2C, MDIO). Automotive Ethernet switching chipsets (i.e., Broadcom, Marvell), TCP/IP, L2/L3, etc. Automotive Ethernet standards.
• Process/Tool Familiarity with: Requirement-Test Case management tools (Polarion preferred). Ubuntu operating system and Command Line Interface. Python scripting. Atlassian software products (Jira/Confluence).
