Propulsion Base Software Low Level Driver Engineer

Job Description / Duties

The Propulsion Base Software Low Level Driver Engineer is responsible for the design and development of embedded base software for EE/core and propulsion control modules, with a strong emphasis on low-level driver development and hardware-software integration. This role includes requirements analysis, detailed design, implementation, integration, and validation of high-performance, safety-critical software components.

The engineer will lead complex driver development activities, interface directly with hardware and semiconductor teams, and ensure robust, production-ready software aligned with AUTOSAR architecture and automotive standards. Deep expertise in microcontroller peripherals, silicon behavior, and low-level debugging is critical to success in this role.

Key Responsibilities

• Develop and integrate hardware abstraction and MCAL drivers, including customization and optimization of AUTOSAR MCAL modules.

• Implement device drivers for advanced peripherals such as SPI, I2C, UART, SENT, CAN, LIN, ADCs, PWM, GTM, timers, watchdogs, DMA, and interrupt controllers.

• Design and develop drivers for power electronics interfaces, including HSD/LSD drivers, H-Bridge control, injector drivers, and gate driver IC interfaces.

• Interface directly with microcontroller registers, memory-mapped I/O, and peripheral control units, ensuring correct initialization, configuration, and runtime behavior.

• Analyze and interpret hardware schematics, MCU reference manuals, and datasheets to design accurate and efficient driver implementations.

• Lead hardware-software integration and bring-up activities, including early silicon validation and debugging on prototype ECUs.

• Perform advanced debugging of low-level issues using Lauterbach, oscilloscopes, logic analyzers, trace tools, and bus analyzers.

• Diagnose and resolve timing, concurrency, interrupt, and multicore synchronization issues in real-time environments.

• Optimize drivers for deterministic real-time performance, low latency, efficient memory usage, and high reliability.

• Collaborate with Base Software Architecture teams to ensure alignment with AUTOSAR stack, RTE integration, and OS scheduling.

• Conduct detailed reviews of requirements, low-level design, register configurations, and embedded C/C++ implementations.

• Ensure compliance with MISRA-C, ASPICE, and ISO 26262, including support for safety mechanisms such as diagnostics, fault handling, and safe states.

• Design and execute driver-level verification strategies, including unit testing, integration testing, hardware validation, and fault injection.

• Contribute to virtualization, SIL/HIL, and simulation-based validation of low-level drivers.

• Develop and maintain detailed technical documentation, including register-level design specs, timing diagrams, and interface definitions.

• Collaborate with semiconductor vendors, hardware teams, and ECU suppliers to debug silicon-level issues and ensure correct driver behavior.

• Support production software delivery, vehicle integration, and launch activities.
