Senior Systems Engineer / Linux Plumber (OS Tooling & Distro Customization)

## Company: Qualcomm Europe, Inc. Italy Branch Office ## Job Area: Engineering Group, Engineering Group > Software Engineering General Summary: We are looking for a Linux Plumber to join our team of world-class engineers. While our kernel team focuses on upstream development and subsystem internals, your mission will be to bridge the gap between the kernel and user space. You will be the architect and mechanic of our custom operating system environment, responsible for building robust OS-level tooling, optimizing the user-space/kernel-space boundary, and driving our custom distribution engineering. In this role, we strictly adhere to a "mainline first" philosophy, ensuring our work is pushed upstream rather than maintaining fragmented forks. You will work in exceptionally close collaboration with an elite team of Qualcomm open-source engineers, co-developing cutting-edge platforms and ensuring our custom Linux distribution seamlessly integrates with upstream developments. Key Responsibilities * Distro Customization & Release Engineering: Own the architecture, assembly, and maintenance of our custom Linux distribution (including rootfs, package management pipelines, and image generation). * Upstream-First Development: Design and build system-level components with an upstream-first mindset, ensuring code is destined for mainline project acceptance. * Debian Ecosystem Management: Maintain, build, and optimize our package ecosystem, leveraging deep Debian packaging mechanics to ensure rock-solid stability and reproducibility. * OS-Level Tooling: Design and build reliable system-level tools, utilities, and daemons in C, Go, or Rust to interface with custom hardware and kernel features. * Boot & Init Optimization: Optimize the early boot pipeline (bootloaders, initramfs, systemd/init systems) for speed, security, and deterministic behavior. * Cross-Team Collaboration: Act as the technical bridge between our internal teams and Qualcomm’s upstream engineering stars to align OS plumbing with next-gen silicon capabilities. Minimum Qualifications: • Bachelor's degree in Computer Science, Electrical/Electronics Engineering, Engineering, or related field and 6+ years of Hardware Engineering or related work experience. OR Master's degree in Computer Science, Electrical/Electronics Engineering, Engineering, or related field and 5+ years of Hardware Engineering or related work experience. OR PhD in Computer Science, Electrical/Electronics Engineering, Engineering, or related field and 4+ years of Hardware Engineering or related work experience. Technical Qualifications Must-Haves (The "Plumbing" Core): * Deep Linux Internals: Strong understanding of Linux OS architecture (process lifecycle, memory management, VFS, networking stack). * Containerization & Sandboxing: Proficiency in using containerization and isolation technologies (e.g., Docker, LXC, Podman) to architect reproducible CI/CD build pipelines and enforce granular, secure, on-device application access control. * Systems Programming: Proficiency in C and at least one modern systems/automation language (Go, Rust, or advanced Python/Bash). * Upstream Philosophy: Experience contributing to or navigating open-source mailing lists, maintaining a strict adherence to mainline-first development. * User-Kernel Boundary: Hands-on experience working with systemd, udev, D-Bus, network configuration, and standard Linux CLI plumbing. Nice-to-Haves (Big Pluses): * Debian Expert: Strong expertise in Debian packaging (dpkg, apt, debootstrap), maintaining custom repositories, and managing complex dependency trees. * Familiarity with Linux security primitives (Namespaces, Cgroups, SELinux/AppArmor, dm-verity). Cultural & Team Fit * The "Glue" Mentality: You enjoy collaborating closely with pure kernel engineers on one side and application/cloud engineers on the other. * Open-Source Citizen: You thrive in the public eye of open-source development and are comfortable collaborating with external industry leaders. * Pragmatic Problem Solver: You care about building stable, maintainable, production-ready systems over theoretical perfection. Why Join This Team? You will work alongside world-class kernel experts and rub shoulders daily with some of the top open-source minds at Qualcomm. You won't be siloed into a single subsystem; instead, you will have a massive impact on the overall performance, reliability, and developer experience of our entire OS platform. We heavily support open-source contributions, encourage participating in the broader Linux plumbing community, and strictly back a mainline-first engineering culture. *References to a particular number of years experience are for indicative purposes only. Applications from candidates with equivalent experience will be considered, provided that the candidate can demonstrate an ability to fulfill the principal duties of the role and possesses the required competencies.
