Vehicle-Level Troubleshooting

• Diagnose and resolve integration issues spanning hardware, software, calibration, instrumentation, and wiring
• Support problem investigation and issue tracking through systems such as PRTS and GIM

Development and Fleet Support

• Participate in development trips, assembly plant activities, prototype shop activities, garage support, and fleet testing as needed
• Travel is expected to be less than 10%

Experimental Software and Technical Reviews

• Develop and validate experimental software for proposed changes
• Support rapid prototyping and proof-of-concept activities
• Conduct and participate in code reviews for algorithms, software, and specifications
• Ensure alignment between I/O functional requirements and corresponding test cases, This role is categorized as hybrid. This means the selected candidate is expected to report to a specific location at least 3 times a week {or other frequency dictated by their manager}.

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Software Engineering, or a related field
• 3+ years of experience in automotive electronics, embedded systems, or control module development
• Proficiency in Python, C, and C++
• Hands-on experience with Hardware-in-the-Loop (HIL) systems and vehicle diagnostics
• Strong knowledge of automotive communication protocols including CAN, LIN, and Ethernet
• Experience working with embedded Android and Linux systems
• Strong troubleshooting skills across hardware and software integration domains
• Experience supporting experimental software development and rapid prototyping
• Strong communication, documentation, and cross-functional collaboration skills, * Experience with vehicle calibration and instrumentation
• Familiarity with ETAS INCA
• Familiarity with dSPACE and AMS
• Familiarity with Autobot and Robot Framework
• Familiarity with Vehicle Spy, Vector CANalyzer, and CANoe
• Working knowledge of TCP/IP, UDP, and Wireshark
• Strong problem-solving mindset with the ability to work effectively across cross-functional teams
