AV Platform OS Staff SW Engineer

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. 

The  Staff Software Engineer – Platform OS  will provide technical leadership for  Linux/QNX-based platform OS development on current production Super Cruise programs , with primary focus on  platform OS debugging, BSP integration, low-level system services, kernel and user-space interfaces, and robust embedded system architecture . This role will lead low-level platform bring-up, cross-layer debugging, and integration of core OS services required to deliver a robust, secure, and production-ready compute platform for vehicle programs. 

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 operate 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 platforms. 

• Experience integrating  Linux and/or QNX BSPs, platform software drops, supplier deliverables, and internal baselines . 

• Experience in  automotive, ADAS, AV, robotics, or other safety-critical systems . 

• Familiarity with  ROS or mixed-OS environments  involving Linux, QNX, or RTOS systems. 

• Experience with  secure boot, signed images, system hardening, HSM integration, and OTA/software update flows . 

• Experience with system performance tuning across  CPU, memory, latency, throughput, and I/O . 

• Experience with  multi-core, SMP, or AMP  embedded system configurations. 

• Experience supporting validation on  benches, HIL rigs, and target ECUs . 

• Experience influencing supplier technical direction and reviewing low-level architecture and implementation quality. 

• Experience mentoring senior and mid-level engineers in platform OS and debugging disciplines.
