Network Test Automation Engineer

Network Test Automation EngineerCompany is helping an on-demand, autonomous ride-hailing company hire a Network Test Automation Engineer to develop scalable automated testing solutions that validate the performance, reliability, and compliance of Ethernet-connected sensor networks across its autonomous vehicle platform. In this role, you’ll build and maintain automation frameworks for network validation while partnering with Systems, Integration, Software, and Sensor Engineering teams. You’ll develop diagnostic and fault-injection tooling, configure bench and Hardware-in-the-Loop (HIL) environments, and validate network interoperability across sensors, switches, and other connected vehicle systems. The ideal candidate is an experienced test automation engineer with strong Python development skills and deep knowledge of Ethernet networking, protocols, and diagnostic tools. You’re comfortable debugging across the full OSI stack, developing scalable test frameworks, and working across hardware and software environments to identify complex network integration and performance issues.As a Network Test Automation Engineer, you'll:Build and maintain Python-based automation frameworks for Ethernet compliance, integration, and performance testing.Develop PCAP/tcpdump tooling and fault-injection scripts to validate ARP, ICMP, FCS, link-loss, and failure-recovery scenarios.Configure and manage VLAN-segmented (802.1Q) network topologies across bench and HIL environments, including power supplies, DAQ systems, and relay controls.Validate interoperability between network switches and sensors and support compliance with security and PPAP requirements for Ethernet ECUs.Develop and maintain technical documentation for automation frameworks, test methodologies, and system configurations.Ideal candidate profileBonus Qualifications: DoIP and UDS over IP (highly preferred) Automotive Ethernet standards: 100BASE-T1, BroadR-Reach, H-MTD/FAKRA connectors Time sync protocols: IEEE 1588v2/PTP, 802.1AS in bench/air-gapped environments Advanced Linux networking and HIL infrastructure experience (DAQ, relay-controlled power rails)Daily tasksThe Advanced Hardware Engineering team is looking for a Network Test Automation Engineer to build and maintain automation frameworks that validate Ethernet-connected sensor networks on our AV platform.
