MCU Networking & Diagnostics Engineer

Role Purpose

Design, develop, integrate, and validate MCU-based automotive communication and diagnostic software, ensuring robust vehicle-network connectivity, standards-compliant diagnostics, reliable fault handling, and traceable delivery across ECU programs.

Main Responsibilities

Core duty description: Design and configure MCU communication stacks and develop diagnostic services for automotive applications.

• Design and configure MCU communication stacks for CAN, CAN FD, LIN, Ethernet, SOME/IP, and transport protocols based on project architecture.
• Develop and integrate diagnostic services using UDS, DoIP, OBD, DTC management, diagnostic sessions, security access, and routine control.
• Configure AUTOSAR communication and diagnostic modules, including COM, PduR, CanIf, CanTp, Dcm, Dem, NvM interfaces, and Ethernet-related services where applicable.
• Translate customer signal databases, diagnostic specifications, and network descriptions into maintainable software configurations and interface contracts.
• Implement network management, wake-up and sleep handling, communication control, timeout supervision, bus-off recovery, and degraded-mode behavior.
• Perform bench, SIL, HIL, and vehicle-level debugging using traces, bus logs, diagnostic logs, and MCU runtime measurements.
• Ensure bidirectional traceability from networking and diagnostic requirements through design, implementation, configuration, and verification evidence.
• Coordinate with system, BSW, application, validation, cybersecurity, and customer teams to resolve interface issues and deliver production-ready releases.

Key Requirements

• Strong embedded C development and debugging experience on automotive microcontrollers.
• Hands-on knowledge of CAN, CAN FD, LIN, Ethernet, SOME/IP, DoIP, UDS, ISO-TP, OBD, and vehicle network management concepts.
• Experience with AUTOSAR Classic communication and diagnostic BSW configuration, integration, and issue analysis.
• Ability to interpret DBC, ARXML, ODX, CDD, diagnostic extracts, signal matrices, and customer interface specifications.
• Proficiency with bus analyzers, debuggers, diagnostic testers, oscilloscopes, and log-analysis methods.
• Good understanding of ASPICE engineering practices, functional safety awareness, cybersecurity constraints, and disciplined defect resolution.

Nice to Have

• Experience with Vector CANoe, CANalyzer, CANape, DaVinci Configurator/Developer, EB tresos, or equivalent automotive tools.
• Exposure to bootloaders, secure diagnostics, OTA or flash programming, Ethernet test tools, scripting, and test automation.

Other Details

Bachelor's or Master’s degree in Electronics, Electrical Engineering, Computer Science, Embedded Systems, Automotive Engineering, or a related discipline. Equivalent relevant industry experience may also be considered.

Expected leadership behaviors include owning networking and diagnostic delivery outcomes, promoting reusable configurations, and coaching engineers in protocol analysis and systematic debugging.
