• Hands-on experience with Linux, QNX in production environments.
• Proficiency in Embedded C/C++ for low-level software.
• Experience with boot issues, IPC, and device bring-up.

Responsibilities

• Lead Linux/QNX platform OS development and integration for current production Super Cruise programs.
• Own BSP bring-up, integration, and debugging across Linux- and QNX-based environments.
• Design, implement, and maintain low-level platform services, system daemons, and resource-managed interfaces.
• Define platform OS architecture including IPC, scheduling, interrupts, and system startup flows.
• Develop Embedded C/C++ for OS components, BSP layers, drivers, and system libraries.
• Drive board and platform bring-up for Super Cruise hardware, including clocks, memory, PCIe, UART, SPI, I2C, and peripherals.
• Debug cross-layer issues using logs, traces, dumps, and lab tools.
• Collaborate with silicon vendors, security teams, validation teams, and release teams.

Job Description

Job Summary

The AV Platform team designs, develops, and maintains the foundational embedded software platform for GM's software-defined vehicle (SDV) and AV solutions, including operating systems, board support packages (BSP), drivers, and the core software stack for high-compute SoCs.

What You'll Do

• Lead Linux/QNX platform OS development and integration for current production Super Cruise programs , ensuring BSP, drivers, platform services, middleware, and core OS components o perate as a cohesive, production-ready system.
• Own platform BSP bring-up, integration, and debugging across Linux- and QNX-based environments, including boot flow, startup, board configuration, peripheral enablement, and low-level system initialization.
• Design, implement, and maintain low-level platform services, system daemons, kernel-adjacent components, and resource-managed interfaces for custom hardware and core platform functionality.
• Define and maintain key aspects of platform OS architecture , including process and service partitioning, IPC mechanisms, scheduling behavior, interrupt handling, and system resiliency.
• Develop software in Embedded C/C++ for low-level operating system components, board support package layers, hardware abstraction, drivers, and system libraries.
• Drive board and platform bring-up for current production of Super Cruise hardware, including clocks, memory, storage, networking, PCIe, UART, SPI, I2C, and other platform peripherals.
• Debug complex cross-layer issues spanning bootloaders, kernels, OS services, drivers, middleware, and applications using logs, traces, dumps, and lab tools.
• Use platform debugging and performance tools such as gdb , core dumps, JTAG, serial consoles, tracing, logging, and bench instrumentation to isolate and resolve system issues across Linux and QNX environments.
• Define and maintain clean interfaces between OS/BSP, platform middleware, vehicle software layers, and application teams .
• Support and improve platform reliability through requirements generation, automated testing, CI/CD integration, issue tracking, code reviews, and regression validation .
• Partner closely with silicon vendors, suppliers, security teams, validation teams, and release teams to review designs, close interface gaps, and ensure program execution.
• Drive technical direction for platform OS architecture , including scalability, performance, fault isolation, maintainability, and debug-ability.
• Mentor engineers on platform OS internals, BSP architecture, bring-up strategy, debugging techniques, and integration best practices .
• Provide regular technical status, risks, and mitigation plans to leadership and cross-functional stakeholders.
• Perform other related duties as assigned.

Basic Qualifications

• 12+ years of experience in embedded systems, platform OS, BSP, or low-level systems software development.
• Strong hands-on experience with Linux, QNX, or other embedded/POSIX operating systems in production or advanced embedded development environments.
• Strong proficiency in Embedded C/C++ development for low-level system software.
• Experience with platform OS debugging , including analysis of boot issues, process or service failures, IPC or synchronization issues, memory or timing issues, and device bring-up problems.
• Experience designing and implementing low-level platform services, system daemons, or resource-managed interfaces .
• Solid understanding of embedded OS architecture , including process isolation, scheduling, interrupts, IPC, services, and system startup flows.
• Experience with board bring-up and BSP integration on ARM or x86-based SoCs.
• Experience with bootloaders, startup flows, hardware initialization, and board configuration for embedded platforms.
• Demonstrated experience debugging issues across multiple layers of the stack, including bootloaders, kernels, OS services, drivers, middleware, and applications.
• Experience building, testing, and shipping production-quality embedded/POSIX systems .
• Experience with CI/CD pipelines , build systems, and integration of workflows in large multi-team environments.
• Familiarity with common hardware interfaces and protocols such as PCIe, Ethernet, CAN, SPI, I2C, UART, USB, and storage subsystems .
• Strong collaboration, communication, and technical leadership skills.

Preferred Qualifications

• Experience with current production Super Cruise programs or similar high-compute automotive SoC platf
