About the role

Key responsibilities & impact

Own the overall ECU system architecture: MCU selection, power architecture, memory, I/O, network interfaces, boot and update concepts, and diagnostics.
Define and maintain system and subsystem requirements, including performance, resource budgets (CPU, RAM, flash), and latency constraints.
Lead HW/SW partitioning and interface definitions.
Develop and maintain communication architectures including message maps and bandwidth/load assessments.
Define ECU-level functional safety concepts (ASIL allocation, safety mechanisms, monitoring concepts) in alignment with ISO 26262 and system safety engineering.
Define ECU-level cybersecurity concepts (secure boot, secure flashing, secure diagnostics, key handling) in alignment with relevant standards.
Ensure alignment with vehicle electrical architecture and network strategies; participate in architecture reviews and change control forums.
Lead architecture and design reviews, drive systematic root-cause analysis for cross-domain issues, and guide corrective actions.
Collaborate with controls, software, hardware, diagnostics, calibration, safety, and manufacturing teams to ensure the ECU design meets program cost, timing, quality, and feature objectives.
Coordinate with suppliers on architectural topics (HW schematics, PCB layout constraints, BSW stacks, AUTOSAR configurations), ensuring compliance with internal standards.
Own and maintain architecture documentation: block diagrams, interface control documents, safety and security concepts, configuration guidelines.
Provide technical leadership and mentoring to engineers; influence without direct authority across multiple teams.
