• Strong RF fundamentals, wireless systems, and interference mechanisms.
• Experience with RF test equipment including spectrum analyzers and network analyzers.
• Familiarity with OTA testing and RF performance validation.
• Exposure to RF simulation tools such as CST/HFSS/FEKO.
• Automotive wireless know-how is a plus (infotainment, telematics, ADAS).

Responsibilities

• Evaluate RF desense performance across vehicle systems and subsystems.
• Measure receiver sensitivity degradation from interference sources.
• Identify RF performance risks early in design and integration.
• Support RF troubleshooting activities at vehicle/subsystem level.
• Perform conducted and over-the-air RF testing.
• Conduct sensitivity, desense, coexistence, and antenna isolation measurements.
• Validate RF coexistence across LTE, 5G, Wi‑Fi, Bluetooth, and GNSS.
• Develop, execute, and document test plans and validation activities.
• Analyze test results and recommend engineering actions.
• Investigate interference sources within vehicle electronics.
• Diagnose issues from processors, memory, power, displays, and interfaces.
• Use lab equipment: spectrum/network analyzers, signal generators, near-field probes.
• Conduct root cause investigations and regression testing.
• Collaborate with GM hardware engineering teams during product development.
• Review PCB layouts for RF interference risks.
• Support grounding/shielding/isolation/signal integrity improvements.
• Recommend mitigation strategies: shielding, filtering, antenna tuning, software fixes.
• Provide feedback for future GM RF design methodologies.
• Work with RF, antenna, hardware, PCB, mechanical, software, and systems teams.
• Collaborate with suppliers and external test partners.
• Support FCC, CE, and OEM regulatory testing.
• Document test procedures, findings, and recommendations.
• Contribute to RF best practices and lessons learned.
• Support evolution of GM's internal RF validation methods.
