Job Description

Position Overview
Need highly skilled and analytical Digital Key Engineer to lead the implementation, validation, and
debugging of next-generation vehicle access systems. Person will be responsible for ensuring seamless,
secure interoperability between smartphone devices and vehicle architectures and will serve as the core
technical expert for root-cause analysis, defect triage, and physical/protocol-layer timing analysis across
NFC, BLE, and UWB channels, closely aligning with Car Connectivity Consortium (CCC) standards.

Key Responsibilities
 End-to-End Implementation: Oversee the integration of CCC Digital Key specifications within the
vehicle architecture, ensuring strict compliance with security and privacy requirements.
 Defect Triage & Root Cause Analysis: Act as the primary technical point for identifying, isolating, and
tracking system defects across hardware, embedded software, and mobile application layers.
 Protocol & Timing Analysis: Analyze time-critical messaging sequences (ranging from BLE discovery
to UWB distance bounding) using logic analyzers, protocol sniffers, and oscilloscope captures.
 Interoperability Validation: Test and debug communication performance variations across diverse
mobile hardware platforms, operating systems (iOS/Android), and environmental conditions.
 Performance Tuning: Optimize physical-layer connection workflows to meet strict latency thresholds
for vehicle wake-up, welcome lighting, and hands-free passive entry.
 Cross-Functional Collaboration: Partner with Tier-1 suppliers, internal software teams, and
cybersecurity experts to address vulnerabilities and architectural bottlenecks.
Technical Requirements & Qualifications
 Education: Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, Embedded
Systems, or a related technical discipline.
 Connectivity Standards: Deep technical knowledge of the Car Connectivity Consortium (CCC)
Digital Key Architecture, including global standards for NFC, BLE, and UWB wireless technologies.
 Analysis Tools: Proven proficiency with network and hardware analysis tools such as Vector
CANoe/CANalyzer, Wireshark, BLE sniffers, and UWB/NFC protocol analyzers.
 Timing & Debugging: Demonstrated experience troubleshooting RF communication timing
constraints, signal propagation bottlenecks, and cryptographic handshake latencies.
 Automotive Networks: Solid understanding of vehicle networking protocols including CAN, CAN-FD,
LIN, and Automotive Ethernet.
 Security Fundamentals: Familiarity with Secure Elements (SE), GlobalPlatform standards, Public Key
Infrastructure (PKI), and asymmetric cryptography.

Preferred Skills
 Experience developing or testing mobile wallet integrations (Apple Wallet, Google Wallet, Samsung
Wallet).
 Hands-on background with automated hardware-in-the-loop (HIL) testing rigs and script development
(Python, CAPL).
 Active participation in CCC plugfests, working groups, or compliance certification programs.
