Job description

As a Wireless Validation Engineer, you will develop, document, and execute unit and system-level validation tests for network-connected devices. This includes mission-critical 4G-LTE, 5G-NR, Wi-Fi, and Bluetooth wireless interfaces, integrated with Zoox’s on-vehicle and cloud-based networks. You will collaborate with engineers to ensure network performance meets quality of service targets, including availability. You will be hands-on to develop and execute test frameworks for prototypes and commercial system releases, ensuring network compliance with international regulations. We seek an expert, enthusiastic, innovative, and self-starting individual to join our team.

In this role, you will:

• Execute Tests - Conduct hands-on functional, compliance, performance, environmental, and reliability testing on wireless and fixed networks in-house and via external labs. Develop and execute test cases to analyze 4G-LTE, 5G-NR, Wi-Fi, Bluetooth, Ethernet, and IP behavior internally and with partners. Collaborate with suppliers and external test houses for Ethernet and IP network validation. Identify root causes of failures, whether found internally or externally. Perform or commission conformance testing for regulatory requirements, using both in-house and external resources as needed.
• 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.

Qualifications:

• B.S. in Electrical Engineering, telecommunications or a similar discipline
• 10+ years of professional work experience
• Hands-on experience configuring/programming wireless test platforms (Keysight, Rohde & Schwarz) and testing/troubleshooting Automotive Ethernet products,
• Expertise in Ethernet standards (IEEE 802.1AS, 802.11), IP network protocols, and 3GPP 4G-LTE / 5G-NR network architecture
• 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).
