Qnx Jobs (NOW HIRING)

Job Summary

The AV Platform team designs, develops, andmaintainsthe 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.

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

WhatYou'llDo

• LeadLinux/QNX platform OS development and integrationforcurrent production Super Cruise programs, ensuring BSP, drivers, platform services, middleware, and core OS componentsoperateas a cohesive, production-ready system.

• Ownplatform BSP bring-up, integration, and debuggingacross Linux- and QNX-based environments, including boot flow, startup, board configuration, peripheral enablement, and low-level system initialization.

• Design, implement, andmaintainlow-level platform services, system daemons, kernel-adjacent components, and resource-managed interfacesfor custom hardware and core platform functionality.

• Define andmaintainkey aspects ofplatform OS architecture, including process and service partitioning, IPC mechanisms, scheduling behavior, interrupt handling, and system resiliency.

• Develop software inEmbedded C/C++for low-level operating system components, board support package layers, hardware abstraction, drivers, and system libraries.

• Driveboard and platform bring-upfor currentproduction ofSuper Cruise hardware, including clocks, memory, storage, networking, PCIe, UART, SPI, I2C, and other platform peripherals.

• Debug complex cross-layer issues spanningbootloaders, kernels, OS services, drivers, middleware, and applicationsusing logs, traces, dumps, and lab tools.

• Use platform debugging and performance tools such asgdb, core dumps, JTAG, serial consoles, tracing, logging, and bench instrumentationto isolate and resolve system issues across Linux and QNX environments.

• Define andmaintainclean interfaces betweenOS/BSP, platformmiddleware, vehiclesoftware layers, and application teams.

• Support and improve platform reliability throughrequirements 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 forplatform OS architecture, including scalability, performance, fault isolation, maintainability, and debug-ability.

• Mentor engineers onplatform 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

• StrongproficiencyinEmbedded C/C++development for low-level system software.

• Experience withplatform 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 implementinglow-level platform services, system daemons, or resource-managed interfaces.

• Solid understanding ofembedded OS architecture, including process isolation, scheduling, interrupts, IPC, services, and system startup flows.

• Experience withboard bring-upand 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 shippingproduction-quality embedded/POSIX systems.

• Experience withCI/CD pipelines, build systems, andintegration ofworkflows in large multi-team environments.

• Familiarity with common hardware interfaces and protocols such asPCIe, Ethernet, CAN, SPI, I2C, UART, USB, and storage subsystems.

• Strong collaboration, communication, and technical leadership skills.

Preferred Qualifications

• Experience withcurrent production Super Cruise programsor similar high-compute automotive SoC platforms.

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

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

• FamiliaritywithROSor mixed-OS environmentsinvolving Linux, QNX, or RTOS systems.

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

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

• Experience withmulti-core, SMP, or AMPembedded system configurations.

• Experience supporting validation onbenches, 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.
