Senior RF Coexistence & Desense Engineer

Jobtailor; California (MO); On-site; USD 100,000 - 150,000; Full time

Job summary

Jobtailor is seeking an experienced RF Engineer to evaluate desense performance across vehicle systems and perform OTA RF testing. You will measure sensitivity degradation from interference and identify RF risks early in design, collaborating with hardware, software, and systems teams.

The role requires hands-on RF testing expertise, knowledge of CST/HFSS/FEKO, and experience with automotive wireless environments including infotainment and ADAS. On-site in the US is expected.

Qualifications

• Bachelor's or Master's degree in Electrical Engineering or related technical discipline.
• 5+ years of RF engineering, RF validation, or wireless systems development.
• Hands-on RF testing, troubleshooting, or desense analysis experience.
• 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.
