Senior Modem Hardware / RF Engineer - Telematics

About the role

AUMOVIO Korea is looking for a Senior Hardware/RF Engineer to join its Telematics R&D team, which develops next-generation Telematics Control Units (TCUs) for global automotive OEMs. The role combines hardware development with RF design, validation and integration, delivering high-performance platforms that integrate cellular (LTE/5G), GNSS, Wi-Fi, Ethernet and in-vehicle network technologies while meeting automotive standards.

Key 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.
• Optimize RF layout, transmission lines and antenna placement for signal integrity and minimal interference.
• Perform RF testing and troubleshooting with spectrum analyzers, network analyzers and RF chambers.
• Support EMC and RF compliance testing (e.g. CISPR 25, ISO 11452) with test and certification teams.
• Work with software, system, validation and mechanical engineers on system-level integration.
• Interface with component vendors for RF tuning, design reviews and module certification.
• Support hardware bring-up, root cause analysis and failure resolution.
• Maintain schematics, BOMs, validation reports and design guides.

Required profile

• Bachelor's or Master's degree in Electrical Engineering, RF Engineering or a related field.
• 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.

Required skills

• Hardware and RF simulation tools such as Altium, OrCAD, ADS, CST or HFSS.
• Hands-on use of oscilloscopes, spectrum analyzers, VNAs, signal generators and RF measurement tools.
• Familiarity with LTE/5G, GNSS, Wi-Fi and Bluetooth modules.
• Knowledge of CAN, LIN and Ethernet protocols and power management systems.

Applications are submitted via the company's application form together with a resume; applications remain open until the position is filled.
