Senior Hardware Engineer- Wi-Fi/BT Connectivity

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.
