Electrical Hardware Engineer – MCU

Job Description

The Role

General Motors is at the forefront of the transformation of automotive with the electrification of our portfolio and the development of leading-edge central compute connectivity and autonomous capabilities. Our Semiconductor Engineering team is a dynamic high-energy and innovative group focused on the design and commercialization of leading-edge silicon enabling the future of GMs Software Defined Vehicle (SDV) platformscentral compute units aggregators connectivity modules and other controllers.

We are seeking a driven Hardware Engineer MCU to join our Semiconductor Center of this role you will own the microcontroller (MCU) hardware engineering deliverables that bring our in-house ECU designs to lifefrom I/O and resource mapping through application schematic support component-level safety analysis and hands-on board bring-up and validation. You will work shoulder-to-shoulder with ECU design software functional safety and PCB layout teams and collaborate directly with silicon suppliers to ensure our MCU-based platforms are designed right the first time.

• Own MCU I/O and resource mapping for in-house ECU designs reserving and allocating pins across GPIO ADC eMIOS/PWM SPI I2C LIN and other peripherals and optimizing use of I/O expanders and ADC MUXes to meet system requirements.
• Develop and maintain MCU application deliverables including the HSIS signal matrix pin-mapping documentation reference schematics and symbol/library content ensuring alignment with requirements and electrical design intent.
• Lead component-level Design Failure Mode and Effects Analysis (DFMEA) for MCU sub-circuits (power crystal MCU-to-networking MCU-to-PMIC MCU-to-Driver etc.) and ensure findings roll up correctly into ECU (system) level DFMEA.
• Establish and execute electrical characterization and functional test plans for MCUs and supporting silicon including board bring-up voltage-rail and ADC verification and interface validation to confirm design intent ahead of formal qualification.
• Perform hands-on debug and validation using tools such as oscilloscopes and JTAG/debug probes on ARM cores including GPIO toggling and register-level verification.
• Define MCU-to-peripheral interfaces (PMIC ethernet switch I/O expander etc) and support change-control activities coordinating design changes across suppliers and internal stakeholders.
• Collaborate cross-functionally with ECU hardware design HWIO/software functional safety Power and PCB layout teams to define specifications and align on architectural and system-level requirements.
• Develop clear component specifications within your scope to enable timely sourcing decisions aligned with electronic development and vehicle program milestones.
• Partner with silicon and tooling suppliers (e.g. MCU vendors and analysis partners) to resolve technical issues and align on requirements.
• Stay current with MCU product portfolios supply-chain dynamics and emerging technology roadmaps.

• Bachelors degree in electrical engineering computer engineering or a related field.
• 4 years of experience in hardware design and development including component- or board-level ownership.
• Knowledge of microcontroller subsystems and IP blocks including processor cores memory analog/ADC communication peripherals (SPI I2C UART/LIN CAN ethernet) timers/PWM and GPIO.
• Demonstrated experience with MCU I/O and resource mapping pin planning and translating system/connector requirements into a hardware pin definition.
• Hands-on experience with circuit design and analysis including worst-case analysis DFMEA circuit simulation tools and schematic capture tools (e.g. Mentor Graphics).
• Experience with board bring-up electrical characterization and hardware validation of MCUs or similar silicon.
• Hands-on experience with hardware debugging tools such as oscilloscopes and JTAG/debug probes.
• Exceptional collaboration and teamwork skills; proven ability to work across functional and organizational boundaries.
• Demonstrated ability to manage multiple assignments simultaneously including planning execution and monitoring.
• Strong problem-solving skills and ability to learn quickly.

• Masters degree in electrical engineering computer engineering or a related field.
• Experience with automotive-grade MCUs (e.g. NXP S32K Infineon AURIX or similar) and their supporting PMICs.
• Familiarity with automotive functional safety (ISO 26262) and component/ECU DFMEA methodology.
• Experience with debug/validation toolchains such as Lauterbach TRACE32 and ARM Cortex-M/R core bring-up.
• Familiarity with ECU-level hardware integration HWIO software interaction and requirements-driven design flows.
• Experience contributing to hardware design processes guidelines or tools that enable other engineers.
• Proven track record supporting ECU hardware development from requirements definition through validation.
