Digital Key enables customers to use their phones and other devices to securely access and start their vehicles. These experiences rely on advanced Ultra-Wideband (UWB), Bluetooth Low Energy (BLE) and Near-Field Communication (NFC) technologies that must perform reliably in challenging automotive environments alongside Bluetooth, Wi-Fi, cellular, and GNSS systems. As a Staff Hardware Engineer- UWB/BLE 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 you will collaborate with teams across GM and with leading silicon and module vendors.
Job Responsibility
Act as a hardware and wireless subject matter expert for UWB/BLE within GM's Digital Key and short-range access systems
Define hardware and RF/Wireless requirements for UWB ranging/BLE that support features such as passive entry, passive start, trunk access, and backup 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 UWB/BLE including accuracy, precision, latency, robustness, and reader field strength and alignment in automotive packaging
Provide UWB/BLE input into short range wireless and antenna roadmaps that can scale across nameplates and regions
Lead schematic and PCB layout reviews for UWB/BLE subsystems on Digital Key controllers, focusing on RF paths, antenna and reader interfaces, and coupling paths to other radios
Bring up and debug UWB/BLE hardware in the lab, including front-end components, antennas, readers, power and clocking, calibration, and tuning for real vehicle environments
Develop and execute test plans for UWB ranging across distances, angles, doors or zones, and environments that reflect real customer access paths, as well as NFC card and phone performance in reader locations
Use RF and time domain instrumentation, and over-the-air setups to characterize UWB/BLE performance across voltage, temperature, and mechanical conditions
Lead coexistence analysis and test content for UWB/BLE with Wi-Fi and Bluetooth, Cellular, GNSS, and other radios
Define blocking, defense, and link budget degradation limits for UWB/BLE channels under realistic aggressor conditions, and drive mitigations such as filtering, shielding, containment, and antenna placement and orientation tradeoffs
Coordinate with 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
Ensure UWB/BLE 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 UWB, BLE behavior, limitations, and coverage concepts are correctly reflected in system architecture, algorithms, and test strategies
Build reusable reference test setups for UWB/BLE performance, and coexistence 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
Requirements
Bachelor's degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related field
10+ years of relevant RF or wireless hardware experience
Hands-on experience with UWB, and BLE transceivers and systems, including ranging, link budgets, and RF front end design
Strong understanding of RF fundamentals, propagation, and multi antenna systems, and the ability to reason about interference and coupling paths in dense multi radio designs such as CHM
