射频工程师，Wifi/蓝牙 RF Engineer，WIFI/Bluetooth

The Role We are seeking a highly motivated RF System Engineer to join our R&D team for WIFI/Bluetooth in Shanghai. In this role, you will design, validate, and optimize Wi-Fi and Bluetooth subsystems within Tesla's vehicles.

Responsibilities

• Design the RF system for Wi-Fi (802.11 a/b/g/n/ac/ax/be) and Bluetooth (Classic & BLE) subsystems, ensuring optimal link margin, throughput, and latency under real-world driving conditions.
• Implement comprehensive Conducted test setups. Develop test plans and guidelines to validate RF performance against industry standards (FCC, CE, RED) and internal Tesla performance metrics.
• Utilize advanced RF instrumentation (Spectrum Analyzers, VNA, Signal Generators, Oscilloscopes, Wi-Fi/Bluetooth Protocol Analyzers) to diagnose and resolve complex RF issues, including interference, sensitivity drops, and packet loss.
• Work closely with Hardware, Embedded Software, and Antenna teams to ensure seamless integration of RF subsystems into the vehicle architecture.
• Perform RF simulations and modeling to predict front-end performance, antenna coupling, and system-level link budgets.
• Ensure all RF designs meet global regulatory compliance requirements and automotive EMC/EMI standards.

Technical Qualifications

• Education: Bachelor’s or Master’s degree in Electrical Engineering, RF Engineering, or a related field .
• Deep understanding of Wi-Fi (802.11) and Bluetooth (BLE/Classic) protocols, physical layers, and MAC layer behaviors.
• Strong grasp of electromagnetic wave propagation, RF front-end design (LNA, PA, Mixers, Filters), and impedance matching.
• Experience with Antenna Design and integration in vehicle environments (metal shielding, multipath effects).
• Hands-on experience with RF test equipment including Vector Network Analyzers (VNA), Spectrum Analyzers, Signal Generators, and Wireless Protocol Analyzers (e.g., Keysight, Rohde & Schwarz).
• Proven ability to perform hardware debugging, root cause analysis, and failure isolation in RF systems.

Preferred Qualifications (Nice To Have)

• Experience with UWB or Cellular (4G/5G) technologies is a plus.、
• Familiarity with OTA update mechanisms and wireless security protocols.
• Experience with EMC/EMI pre-compliance testing and mitigation strategies.
• Proficient in Python or C++ for test automation, data analysis, and instrument control (SCPI/VISA).
