• Define and review subsystem interconnect strategies (power RF highspeed data) for connectivity modules including connector selection and placement with attention to EMI/EMC robustness and manufacturability.
• Review design changes for their RF and coexistence impact providing practical guidance to hardware design teams.

RF Systems Performance and MultiRadio Coexistence

• Develop and refine RF performance targets and KPIs for WiFi and Bluetooth (Classic and BLE) ensuring traceability to program requirements and user experience goals.
• Analyze and validate multiradio coexistence across WiFi/BT and neighboring radios (e.g. UWB LTE/5G GNSS NFC and other radios) in shared modules focusing on desense blocking intermodulation and noise coupling paths.
• Propose and evaluate mitigation strategies - such as filtering shielding antenna isolation timing/resource coordination and layout/placement changes.
• Support regulatory and standards compliance by providing RF data participating in EMC/IME reviews and contributing to certification test planning and issue resolution.

Test Planning Validation and Execution

• Define and execute RF and systemlevel validation strategies for:
  • WiFi AP and STA modes across all supported bands and channel widths (2.4/5/6 GHz).
  • Bluetooth Classic and BLEbased use cases (e.g. lowpower peripherals proximitybased experiences and audio).
  • Highthroughput wireless data paths (e.g. wireless streaming) and lowpower/alwayson connectivity behaviors.
• Own WiFi Bluetooth and relevant coexistence test plans and execution across bench RF chambers and invehicle environments for connectivity modules that integrate WiFi/BT.
• Integrate WiFi/BT coexistence coverage into connectivity modules wireless and antenna validation plans; track execution trend data and monitor recurrence using structured dashboards and KPIs.
• Perform detailed RF characterization using spectrum analyzers VNAs VSGs OTA chambers and shielded environments leveraging scriptingbased automation to evaluate performance temperature mechanical tolerances and packaging.
• Troubleshoot and rootcause connectivity issues using oscilloscopes protocol analyzers RF diagnostic tools and logs - driving issues to closure with clear data and recommendations.
• Coordinate environmental and vehiclelevel hardware validation related to WiFi/BT performance ensuring issues are captured reproduced tracked and resolved across programs.

CrossFunctional Leadership and Issue Resolution

• Collaborate closely with hardware systems software antenna validation manufacturing and supplier teams throughout the full development lifecycle for connectivity ECUs.
• Drive resolution of WiFi/BT performance and coexistence issues by structuring problems designing targeted experiments analyzing logs and measurements and coordinating corrective actions with domain experts.
• Represent WiFi/BT connectivity hardware considerations in crossfunctional reviews and program forums providing datadriven recommendations.

Documentation Mentorship and Continuous Improvement

• Prepare highquality technical documentation including RF system block diagrams validation strategies test reports and ERD/CTRS updates suitable for design and program reviews.
• Develop reusable WiFi/BT test setups automation scripts and scalable dashboards to enable consistent RF and coexistence validation across modules and vehicle programs.
• Share best practices and provide informal mentorship to junior engineers and lab personnel in RF design test methodologies and debug approaches.
• Contribute to the definition and continuous improvement of GMs wireless hardware standards design guidelines and RF review checklists.

• Bachelors degree (or higher) in Electrical Engineering Computer Engineering or a related field with 5 years of relevant experience with a bachelors degree.
• Substantial experience in RF and connectivity hardware design and validation for WiFi and Bluetooth (Classic and BLE) ideally including multiradio modules (e.g. GNSS cellular) in automotive or other highreliability environments.
• Experience with wireless protocols and features relevant to modern vehicle connectivity and/or other IoT products (e.g. WiFi 6/6E WiFi 7 readiness advanced Bluetooth audio Matter or similar ecosystems).
• Hands-on experience with WiFi and Bluetooth protocol analyzers/sniffers for packet capture protocol-level analysis debugging and root-cause investigation.
• Handson experience with RF lab equipment (spectrum analyzers VNAs VSAs oscilloscopes OTA chambers shielded boxes) and RF characterization methods.
• Proven ability to define and maintain hardware/system requirements (e.g. ERDs CTRS) and to translate system use cases into executable test plans and validation strategies.
• Solid understanding of multiradio coexistence EMC/EMI considerations and practical mitigation techniques (filtering shielding antenna isolation timedomain coordination) for WiFi/BT in dense RF environments.
• Strong technical communication documentation and crossfunctional collaboration skills with comfort driving technical discussions and issue resolution.
