MCU Networking & Diagnostics Engineer

Quick Facts

MCU Networking & Diagnostics Engineer focused on automotive communication stacks and standards-compliant diagnostics.

Description

Design, develop, integrate, and validate MCU-based automotive communication and diagnostic software. Configure communication stacks for CAN, CAN FD, LIN, Ethernet, SOME/IP, and transport protocols, and implement diagnostic services including UDS, DoIP, OBD, DTC management, diagnostic sessions, security access, and routine control. Deliver traceable, production-ready ECU networking and diagnostic releases with robust fault handling.

Responsibilities

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

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
• Bachelor’s or Master’s degree in a relevant engineering/computer science field, or equivalent relevant experience

Benefits

Leadership expectations include owning networking/diagnostic delivery outcomes, promoting reusable configurations, and coaching engineers in protocol analysis and systematic debugging.
