Job Description

NAD - Modem HW/RF Engineer in Architecture and Networking Solutions Korea (Telematics)

Position Overview: The Senior Hardware/RF Engineer to join our Telematics R&D team, responsible for developing next-generation Telematics Control Units (TCUs) for global automotive OEMs. We deliver high-performance hardware platforms that integrate cellular (LTE/5G), GNSS, Wi-Fi, Ethernet, and in-vehicle network technologies, with strict adherence to automotive standards.

This role combines core hardware development with RF design, validation, and integration, ensuring optimal wireless performance under challenging automotive environments.

Responsibilities:

• Design, develop, and validate automotive-grade hardware including schematics and multi-layer PCB layouts.

• Integrate and evaluate RF components: cellular modems, GNSS modules, Wi-Fi/Bluetooth transceivers, antennas, and RF filters.

• Perform RF layout optimization, transmission line matching, and antenna placement analysis for optimal signal integrity and minimal interference.

• Conduct RF testing and troubleshooting using spectrum analyzers, network analyzers, and RF chambers.

• Support EMC and RF compliance testing (e.g., CISPR 25, ISO 11452) in collaboration with test and certification teams.

• Collaborate with software, system, validation, and mechanical engineers to ensure system-level integration and performance.

• Interface with component vendors for RF tuning, design reviews, and module certification support.

• Support hardware bring-up, root cause analysis, and failure resolution across development and validation phases.

• Create and maintain technical documentation: schematics, BOMs, validation reports, and design guides.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, RF Engineering, or related discipline.

• 7+ years of experience in automotive or embedded hardware development, with at least 3 years focused on RF systems.

• Strong understanding of RF fundamentals: impedance matching, S-parameters, return loss, and radiation patterns.

• Experience with tools such as Altium, OrCAD, ADS, CST, or HFSS for hardware and RF simulation/design.

• Hands-on experience with oscilloscopes, spectrum analyzers, VNA, signal generators, and RF measurement tools.

• Familiarity with cellular (LTE/5G), GNSS, Wi-Fi, and Bluetooth modules and RF design practices.

• Knowledge of vehicle network protocols (CAN, LIN, Ethernet) and power management systems.
