System Architect

GM•Warren, MI

3d•Hybrid

About The Position

Lead the end-to-end architecture of automotive display Electronic Control Units (ECUs), defining and evolving the hardware, software so that systems are safe, scalable, and fit for their intended vehicle and feature roadmaps. Our vision is a world with Zero Crashes, Zero Emissions and Zero Congestion and we embrace the responsibility to lead the change that will make our world better, safer and more equitable for all. We believe we all must make a choice every day – individually and collectively – to drive meaningful change through our words, our deeds and our culture. Every day, we want every employee to feel they belong to one General Motors team.

Requirements

Bachelor’s degree in Electrical Engineering, Computer Engineering, or related degree.
10+ years in embedded automotive ECU development, covering both hardware and software aspects.
Strong knowledge of microcontrollers/SoCs, power supplies, clocks ,memory, and board-level design constraints.
Experience in requirements tools (DOORS, Polarion, RTC).
Experience with in-vehicle networks (CAN/CAN FD, LIN, Ethernet) and related tools (e.g., Vector CANoe/CANalyzer, Vehicle Spy).
Working knowledge of ISO 26262 and ASPICE (or equivalent safety/quality frameworks) as applied to ECU design and verification.

Nice To Haves

MSE preferred.
Familiarity with diagnostics and service (UDS, OBD, DTCs, fault handling strategies).
Proven ability to lead cross-functional technical discussions, drive decisions, and manage complex trade-offs.
Excellent communication and documentation skills.

Responsibilities

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.
