Staff Hardware Engineer- NFC Digital Key Hardware

Job Description
Why Join Us
Digital Key

enables customers to use their phones and other devices to securely access and start their vehicles. These experiences rely on advanced

and

technologies that must perform reliably in challenging automotive environments alongside Bluetooth, Wi‑Fi, cellular, and GNSS systems.

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.

You will be a Staff Wireless Hardware Engineer focused on NFC subsystems used for Digital Key, including NFC readers, Secure Element and controllers. You will split your time between system-level architecture and requirements and hands‑on lab work, including bring‑up, measurements, coexistence testing, and debug. You will partner closely with Vehicle Access and Digital Key, Connectivity, Cybersecurity, Antenna, Validation, Manufacturing, and suppliers to deliver robust solutions that can be reused across programs and platforms.

• 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.

• 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.

• 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.

• 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.

• Build reusable reference test…
