Job summary

N7 Mobile Sp. z o.o. is seeking a Senior / Mid Virtualization Engineer to advance a QEMU/QNX based simulation platform. You will stabilize and evolve the platform, integrate VirtIO devices, and implement SiL Kit time synchronization, ensuring end-to-end automation within CI/CD pipelines.

This full-time role in the United States emphasizes hands-on debugging with Azure DevOps, Git, and GDB, plus strong English documentation and cross-team collaboration.

Qualifications

• Deep experience with QNX RTOS and QEMU internals.
• Solid BSP/SoC peripherals and VirtIO standards knowledge.
• Experience with SiL Kit or virtual clock synchronization.
• Hands-on Azure DevOps, Git, and low-level debugging.

Responsibilities

• Stabilize QEMU platform, fix QNX boot issues, and build a complete virtual boot chain.
• Model virtual devices and integrate VirtIO (net/storage/serial).
• Ensure a single image runs on both HW and QEMU via unified boot flow.
• Develop SiL Kit time synchronization with the virtual clock.
• Automate builds/boots in CI/CD and document memory maps and boot flows.

Job description

N7 is looking for a Senior / Mid Virtualization Engineer to deliver a mission-critical project for our client. In this role, you will stabilize and evolve a QEMU-based simulation platform for QNX, integrate VirtIO devices, and implement SiL Kit time synchronization, ensuring end-to-end automation within CI/CD pipelines.

Fulltime position with flexible start date.

Key Responsibilities

• QEMU & QNX Boot: Stabilize the QEMU platform, resolve QNX boot issues, and implement a complete virtual boot chain (bootloader/boot manager).
• Virtualization & Device Modeling: Integrate VirtIO devices (net, storage, serial) and design prototype virtual device models for unsupported SoC peripherals.
• Single Image Execution: Build environment detection so a single, unmodified production image runs seamlessly on both physical HW and QEMU.
• SiL Kit Integration: Develop and measure time synchronization solutions between SiL Kit and the QEMU virtual clock.
• CI/CD & Tooling: Implement automated build/boot validation in Azure DevOps, integrate GDB debugging workflows, and produce technical architecture artifacts (memory maps, boot flows, BSP gap analysis).

Requirements

• Deep experience with QNX RTOS and QEMU internal architectures.
• Solid understanding of BSP/SoC peripherals, driver dependencies, and VirtIO standards.
• Experience with SiL Kit or virtual clock synchronization.
• Hands-on experience with Azure DevOps, Git, and low-level GDB debugging.
• Strong communication skills in English (for documentation and tech specs).
