• Hands-on experience with network diagnostic tools such as Wireshark, iPerf, tcpdump, traceroute, and ethtool
• Experience with CI/CD pipelines and DevOps practices
• Ability to troubleshoot issues across the full network stack

Preferred Qualifications

• Experience with automotive Ethernet standards (e.g., 100BASE-T1, BroadR-Reach)
• Familiarity with DoIP and UDS over IP
• Knowledge of time synchronization protocols (e.g., IEEE 1588v2/PTP, 802.1AS)
• Experience working in HIL environments, including integration with DAQ systems and relay-controlled power setups

Why Join

• Work on cutting-edge autonomous vehicle technology
• Collaborate with highly skilled, cross-functional engineering teams
• Opportunity to contribute to innovative, real-world systems at scale
