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.
