Full Job Description
Job Description
The Role:

You will be a senior individual contributor in the Wireless Technology organization, with primary responsibility for Wi-Fi and Bluetooth connectivity on multi-radio products. You will:
  • Translate vehicle-level use cases into robust, testable RF hardware and system requirements.
  • Contribute to Wi-Fi/BT RF system architectures defined by Staff/Principal engineers and help drive those architectures into concrete designs and validation plans.
  • Lead RF validation, characterization, and debug across bench, chamber, and in-vehicle environments, with a strong emphasis on multi-radio coexistence.
  • Actively collaborate with GM's compliance teams and external labs in debugging and troubleshoot issues found in Wi-Fi Alliance and Bluetooth SIG certification.


What You Will Do (Responsibilities):

System Definition, Requirements, and Architecture Contribution
  • Translate vehicle-level Wi-Fi/BT use cases into clear, testable hardware and system requirements for connectivity ECUs and subsystems.
  • Develop, maintain, and trace connectivity requirements for Wi-Fi/BT hardware and RF performance, ensuring alignment with program and customer objectives.
  • Contribute to Wi-Fi/BT RF system architectures and connectivity modules - including clocking, filtering, front-end partitioning, and antenna/interconnect concepts.
  • Provide structured feedback from validation, characterization, and field issues back into requirements and architecture documents to drive continuous improvement.


Schematic, Layout, and Interconnect Support
  • Support schematic development and guide PCB layout for Wi-Fi/BT RF signal paths, including PAs, LNAs, FEMs, switches, diplexers, filters, and antenna interfaces.
  • Influence PCB stack-up, routing discipline, impedance control, and grounding strategies to meet GM and industry RF performance margins across voltage, temperature, and environmental conditions.
  • Define and review sub-system interconnect strategies (power, RF, high-speed 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 Multi-Radio Coexistence
  • Develop and refine RF performance targets and KPIs for Wi-Fi and Bluetooth (Classic and BLE), ensuring traceability to program requirements and user experience goals.
  • Analyze and validate multi-radio coexistence across Wi-Fi/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 system-level validation strategies for:
    • Wi-Fi AP and STA modes across all supported bands and channel widths (2.4/5/6 GHz).
    • Bluetooth Classic and BLE-based use cases (e.g., low-power peripherals, proximity-based experiences, and audio).
    • High-throughput wireless data paths (e.g., wireless streaming) and low-power/always-on connectivity behaviors.
  • Own Wi-Fi, Bluetooth, and relevant coexistence test plans and execution across bench, RF chambers, and in-vehicle environments for connectivity modules that integrate Wi-Fi/BT.
  • Integrate Wi-Fi/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 scripting-based automation to evaluate performance vs. voltage, temperature, mechanical tolerances, and packaging.
  • Troubleshoot and root-cause connectivity issues using oscilloscopes, protocol analyzers, RF diagnostic tools, and logs - driving issues to closure with clear data and recommendations.
  • Coordinate environmental and vehicle-level hardware validation related to Wi-Fi/BT performance, ensuring issues are captured, reproduced, tracked, and resolved across programs.


Cross-Functional 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 Wi-Fi/BT performance and coexistence issues by structuring problems, designing targeted experiments, analyzing logs and measurements, and coordinating corrective actions with domain experts.
  • Represent Wi-Fi/BT connectivity hardware considerations in cross-functional reviews and program forums, providing data-driven recommendations.


Documentation, Mentorship, and Continuous Improvement
  • Prepare high-quality technical documentation, including RF system block diagrams, validation strategies, test reports, and ERD/CTRS updates suitable for design and program reviews.
  • Develop reusable Wi-Fi/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 GM's wireless hardware standards, design guidelines, and RF review checklists.


Your Skills & Abilities (Required Qualifications):
  • Bachelor's degree (or higher) in Electrical Engineering, Computer Engineering, or a related field with 5+ years of relevant experience with a bachelor's degree.
  • Substantial experience in RF and connectivity hardware design and validation for Wi-Fi and Bluetooth (Classic and BLE), ideally including multi-radio modules (e.g., GNSS, cellular) in automotive or other high-reliability environments.
  • Experience with wireless protocols and features relevant to modern vehicle connectivity and/or other IoT products (e.g., Wi-Fi 6/6E, Wi-Fi 7 readiness, advanced Bluetooth audio, Matter or similar ecosystems).
  • Hands-on experience with Wi-Fi and Bluetooth protocol analyzers/sniffers for packet capture, protocol-level analysis, debugging, and root-cause investigation.
  • Hands-on 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 multi-radio coexistence, EMC/EMI considerations, and practical mitigation techniques (filtering, shielding, antenna isolation, time-domain coordination) for Wi-Fi/BT in dense RF environments.
  • Strong technical communication, documentation, and cross-functional collaboration skills, with comfort driving technical discussions and issue resolution.


What Will Give You A Competitive Edge (Preferred Qualifications):
  • Master's degree in Electrical Engineering, Computer Engineering, or a related field with 7+ years of relevant experience with a master's degree in similar RF/connectivity roles.
