Requirements

Education: Bachelor's degree in Electrical Engineering, Computer Engineering, Telecommunications, or a similar discipline.
Experience: 6+ years of professional, relevant work experience in electronics development.
Technical Expertise: 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.
Experience with Wi-Fi and Bluetooth Classic/LE protocol and PHY designs.
Proficiency with lab equipment, including oscilloscopes, e-loads, VNAs, and spectrum analyzers.
Experience with regulatory conformance testing and analyzing network diagnostics using tools like Wireshark and Qualcomm QXDM logs.
Familiarity with Ethernet lab equipment (Ixia, Spirent) and associated software (IxNetwork, TTworkbench).

Nice To Haves

Advanced degree (M.S. or Ph.D.) in Engineering.
Experience with team/club competitions (e.g., SAE, FIRST, DARPA).
Foundational knowledge of systems and networking (e.g., systems architecture, memory hierarchy, storage subsystems, routing).
Experience with specific protocols (PCIe, CAN, SPI, I2C, MDIO) and Ethernet standards (IEEE 802.3x).
Familiarity with specific chipsets (e.g., Broadcom, Marvell) and signaling (NRZ and PAM-4).
Certifications such as CCNA, CCNP, or CCIE.
Experience with data acquisition systems (UEI or Keysight), requirement-test case management tools (Polarion), and Atlassian products (Jira/Confluence).

Responsibilities

Test Execution & Analysis: Conduct hands-on functional, performance, environmental, and reliability testing on both physical hardware and network systems. You'll use a variety of tools, from oscilloscopes, VNAs, and environmental chambers to specialized wireless test platforms from vendors like Keysight and Rohde & Schwarz.
Test Infrastructure Development: Select, procure, commission, and configure test equipment and software. Develop custom test assets such as load simulators, test harnesses, and scripts using Python and TTCN. Construct and maintain lab infrastructure, from fixed network test harnesses to RF cabling.
Protocol & System Validation: Develop and execute test cases to analyze the behavior of wireless and fixed networks, including 4G-LTE, 5G-NR, Wi-Fi, Bluetooth, Ethernet, and IP. Collaborate with suppliers to validate network performance and identify the root cause of failures.
Documentation & Compliance: Draft and present detailed documentation, including test plans, design reviews, and data reviews. You will also perform or commission conformance testing for international regulatory requirements, such as FCC emission compliance, PTCRB/GCF test suites, and U.S. MNO conformance testing.
