Staff Hardware Engineer- NFC Digital Key Hardware

Staff Hardware Engineer – NFC Digital Key Hardware Digital Key enables customers to use their phones and other devices to securely access and start their vehicles. These experiences rely on advanced Near‑Field Communication (NFC), Bluetooth Low Energy (BLE) and Ultra‑Wideband (UWB) technologies that must perform reliably in challenging automotive environments alongside Bluetooth, Wi‑Fi, cellular, and GNSS systems. As a Staff Hardware Engineer‑NFC Digital Key Hardware, you will help architect, design, and validate the wireless hardware that makes secure, precise Digital Key experiences possible for millions of vehicles and customers worldwide. You will work at the intersection of hardware, RF systems, security, and vehicle access, and collaborate with teams across GM and leading silicon and module vendors. Responsibilities Act as a hardware and wireless subject matter expert for NFC within GM’s Digital Key and short‑range access systems. Define hardware and requirements for NFC readers that support features such as passive entry, passive start, trunk access, and NFC card and phone access. Lead the concept and requirements for vehicle Digital Key system development. Translate vehicle level use cases and customer scenarios into clear link budgets and performance targets for NFC, including accuracy, precision, latency, robustness, and reader field strength and alignment in automotive packaging. Provide NFC input into short‑range wireless and antenna roadmaps that can scale across nameplates and regions. Hands‑on RF Design, Bring‑up, and Validation: lead schematic and PCB layout reviews for NFC and Secure Element subsystems on Digital Key controllers, and NFC readers, focusing on NFC reader coil geometry, tuning networks, interaction with nearby metals (for example, the wireless charging coil), and coupling paths to other radios. Bring up and debug Digital Key hardware in the lab, including reader front‑end components, coils, tuning networks, power and clocking, calibration, and performance optimization for real vehicle environments. Develop and execute NFC‑focused test plans covering realistic positions, orientations, doors or zones, and packaging conditions that reflect real customer access paths, and validating behavior for key Digital Key use cases. Use RF and time domain instrumentation to conduct NFC‑specific tests such as field strength and load‑modulation maps over the pad area, coupling and detuning versus phone cases and nearby metals, and ISO/IEC 14443/15693 interoperability and timing margin checks across voltage, temperature, and mechanical conditions. Short Range Coexistence Leadership: lead coexistence analysis and test content for Digital Key NFC readers in the presence of other technologies, maintaining robust NFC detection and transaction reliability under multi‑radio activities. Coordinate with UWB, BLE, Wi‑Fi, Bluetooth, Cellular, and GNSS teams on time domain and resource sharing strategies where appropriate, ensuring coexistence remains a shared responsibility while you provide technical leadership on problem framing, test design, and mitigation plans. CCC Digital Key, Security, and System Alignment: ensure NFC hardware implementations support current and emerging Car Connectivity Consortium (CCC) Digital Key expectations, particularly for secure, precise ranging and multi device operation. Work with Digital Key system and software leads so that NFC, BLE, and UWB behaviors, limitations, and coverage concepts are correctly reflected in system architecture, algorithms, and test strategies. Execution, Documentation, and Mentorship: build reusable reference test setups for NFC performance that can be used across labs and programs, including setups that directly compare different implementations. Produce clear, structured documentation of requirements, architecture decisions, test strategies, coverage studies, and coexistence analysis that can be used in design reviews, engineering requirements, and supplier communication. Mentor junior wireless, RF and hardware engineers and lab staff, modeling GM behaviors and helping to scale the Wireless Technology organization’s impact on Digital Key and short‑range connectivity. Required Qualifications Hands‑on experience with CCC Digital Key specifications and broader industry trends in digital vehicle access and secure ranging, including standards such as IEEE 802.15.4z and draft 802.15.4ab for UWB ranging and NFC standards like ISO/IEC 14443, ISO/IEC 15693, and ISO/IEC 18092 (or equivalent regional variants). Strong understanding of Electromagnetic fundamentals, and material properties, and the ability to reason about interference and coupling paths in dense automotive designs. Experience with NFC reader antenna and coil design and placement in vehicle contexts optimizing WCM pad geometry, reader orientation, and nearby metal keep‑outs for robust card/phone detection at door, trunk, and center console locations. Demonstrated experience with short‑range coexistence involving NFC, Qi, UWB, BLE, Wi‑Fi and Bluetooth, cellular, and GNSS, including test definition, analysis, and mitigation strategies. Strong written and verbal communication skills and a track record of leading cross‑functional technical initiatives across hardware, software, systems, and supplier teams. Preferred Qualifications Hands‑on experience with UWB, and BLE transceivers and systems, including ranging, link budgets, and RF front‑end design. Experience with RF and hardware design reviews, bring‑up, and debug on complex, multi‑radio boards that integrate NFC, Qi, UWB, BLE, Bluetooth, Wi‑Fi, cellular, and GNSS. Awareness of cybersecurity and privacy considerations for UWB, BLE and NFC systems used for secure vehicle access. Proficiency with RF test equipment and at least one scripting language such as Python for test automation and data analysis. Contributions to patents, standards, or technical publications in UWB, UWB‑NBA, NFC, or short‑range wireless hardware design. Compensation The compensation information is a good faith estimate only.
