Mission:
As the Network Senior Developer, you will be involved the design, implementation, and optimization of vehicle communication networks across electronic and electrical (EE) platforms. Leveraging industry standards such as AUTOSAR, CAN/CAN FD (ISO 11898), Ethernet (IEEE 802.3), and OEM-specific specifications, you will architect and maintain network databases (DBC/LDF/FIBEX/ARXML), ensuring seamless integration of communication matrices and protocols. Your expertise in network topology design, signal routing, and diagnostic-over-communication (DoIP, UDS-on-CAN) will enable robust data exchange, reduce development cycles, and align network architectures with functional safety (ISO 26262) and cybersecurity (ISO 21434) requirements throughout the vehicle lifecycle.
