Propulsion Base Software Low Level Driver Engineer

The PRS Base Software Low-Level Driver Engineer is responsible for the design, development, integration, and validation of low-level driver software for propulsion and electrified powertrain control modules.

Key responsibilities include:

• Design, develop, and maintain embedded low-level driver software including requirements analysis, architecture, coding, integration, and verification.

• Implement hardware interface drivers for peripherals and external devices including high-side and low-side drivers (HSD/LSD), SPI, I2C, H-Bridge interfaces, and motor control drivers (e.g., PWM, FOC, position/speed sensing interfaces).

• Develop and integrate Microcontroller Abstraction Layer (MCAL) components, hardware interface drivers, and complex device drivers supporting propulsion applications.

• Configure and integrate AUTOSAR Basic Software modules such as OS, IOHWAB, FEE, and WDG using Vector or ETAS toolchains.

• Perform hardware-software integration by working with hardware schematics, device reference manuals, and microcontroller documentation.

• Support ECU hardware bring-up and early software enablement activities on new controller platforms.

• Debug and troubleshoot hardware/software integration issues using oscilloscopes, logic analyzers, JTAG debuggers, trace tools, and emulators (e.g., Lauterbach).

• Optimize low-level driver implementations for deterministic real-time performance, efficient memory usage, and reliable peripheral operation on multicore microcontrollers.

• Collaborate with hardware engineering, systems, controls, and supplier teams to ensure proper hardware interface functionality and alignment with propulsion system requirements.

• Ensure alignment with AUTOSAR architecture, including RTE integration and system resource usage.

• Conduct and participate in design reviews, code reviews, and technical inspections to ensure high-quality software deliverables.

• Develop and maintain technical documentation including software design specifications, interface definitions, and test plans.

• Perform software verification and validation activities including unit testing, integration testing, and validation on target hardware (white box, black box, and gray box testing).

• Ensure compliance with automotive software standards and development processes including MISRA-C, ASPICE, and ISO 26262.

• Contribute to continuous improvement of development processes, tools, and methodologies.

• Support vehicle program milestones and production software releases with high-quality, validated deliverables.

• 5 years experience developing or integrating low-level drivers, MCAL, or complex device drivers.

• Experience developing drivers or interfaces for hardware components such as SPI, I2C, HSD/LSD, H-Bridge circuits, timers, ADCs, communication peripherals, and motor control interfaces (PWM, current sensing, position/speed sensors).

• Experience with AUTOSAR Basic Software configuration (e.g., OS, IOHWAB, FEE, WDG) using Vector or ETAS toolchains.

• Experience with multicore automotive microcontrollers and hardware/software integration, including interpreting schematics and device reference manuals.

Preferred Qualifications:

• Experience with embedded C/C++ development (hand coding) in real-time operating system environments.

• Strong understanding of functional safety concepts and experience working within ISO 26262 frameworks.

• Familiarity with automotive software standards such as MISRA-C and ASPICE.

• Experience using embedded development tools including compilers, debuggers, emulators (e.g., Lauterbach), and automation scripting.

• Experience using hardware debugging tools such as oscilloscopes and logic analyzers.

• Experience in software verification and validation including white box, black box, and gray box testing.

• Experience with data acquisition and calibration tools such as ETAS INCA, CANoe, and CANalyzer.
