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 GM's Software Defined Vehicle (SDV) platforms—central compute units, aggregators, connectivity modules, and other controllers.

We are seeking a driven Hardware Engineer – MCU to join our Semiconductor Center of Excellence. In this role you will own the microcontroller (MCU) hardware engineering deliverables that bring our in-house ECU designs to life—from 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.

Responsibilities

• 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.

Qualifications – Required

• Bachelor's 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.

Qualifications – Preferred

• Master's 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.
