Sr. Staff MCU BSW Engineer – OS Design

Job Description – Sr. Staff MCU BSW Engineer – OS Design

Summary:

We are seeking a Sr. Staff MCU BSW Engineer – OS Design to lead the development and integration of real-time operating system (RTOS) components on automotive microcontroller (MCU) platforms. This role focuses on OS architecture, task scheduling, and resource management for safety- and non-safety-critical ECUs, such as Zonal Controllers, Powertrain Modules, and Body Electronics.

As a senior member of the Base Software (BSW) Engineering team at Stellantis, you will work on OS design, driver integration, performance optimization, and compliance with automotive safety and quality standards.

Key Responsibilities:

• Design and implement real-time operating system (RTOS) components, including task scheduling, memory allocation, and timing mechanisms.
• Proven experience as a BSW Architect, delivering solutions for multicore systems, including core allocation strategies and inter-core communication mechanisms.
• Integrate and configure AUTOSAR OS, OSEK, or proprietary RTOS solutions for automotive MCU platforms.
• Optimize OS-level software for efficient memory usage and CPU utilization, enhancing overall system performance, reliability, and determinism through code optimization and configuration tuning.
• Ensure compliance with AUTOSAR standards and functional safety requirements (e.g., ISO 26262, ASPICE, and MISRA C).
• Implemented safety requirements such as memory protection unit, task monitoring, and watchdog.
• Collaborate with hardware, ECU architects, SW requirement engineers and application teams to ensure seamless Software integration and robust OS abstraction.
• Debug using tools such as oscilloscopes, logic analyzers, JTAG debuggers and timing analysis tools.
• Create and maintain detailed software architecture documentation, safety work products, and traceability artifacts.
• Contribute to CI/CD workflows, automated testing, and Test-Driven Development (TDD)
• Work in an Agile development environment and actively participate in code reviews and sprint planning.
• Define and design Wakeup/Sleep strategies to support power management.

Basic Qualifications:

• Bachelor's degree in computer engineering, Electrical Engineering, Computer Science, or a related field
• 10+ years of experience in embedded software development, with a strong focus on RTOS and low-level platform software
• Proficiency in C programming with a deep understanding of real-time system constraints
• Experience with AUTOSAR OS, OSEK, or other embedded operating systems.
• Familiarity with MCU architectures such as ARM Cortex-M, Renesas RH850, or Infineon AURIX
• Strong understanding of the CPU core load distribution
• Strong experience in debugging, timing analysis, and driver development
• Excellent collaboration, documentation, and technical leadership skills

Preferred Qualifications:

• Master's degree in computer engineering, Electrical Engineering, Computer Science, or a related field
• Experience with ASIL-B/D software development and ISO 26262 work products.
• Proficiency in Python, Shell scripting, and automation tool development
• Familiarity with Vector DaVinci, EB tresos, or other AUTOSAR configuration tools
• Familiarity with debugging and trace analysis tools such Vector TA, GLIWA or trace debuggers
• Exposure to power management, state machines, and secure boot in MCU-based ECUs
• Understanding of vehicle communication protocols (CAN, LIN, Ethernet)
