Primary Function of Position The Senior Embedded Linux / Yocto Software Engineer will join the platform team for a robotic-assisted bronchoscopy navigation and biopsy planning software product, reporting to the software development manager. This role owns the Linux operating system and platform-layer software for the procedure planning laptop, a medical image-processing system running a custom Yocto-based Linux distribution. This role owns embedded Linux OS development, Yocto/OpenEmbedded layer and recipe maintenance, secure boot, field software update mechanisms, hardware bring-up for new commercial laptop platforms, and platform-level debugging. The engineer will work closely with application software, security, field service, systems engineering, and hardware teams to maintain and evolve a reliable, secure, and serviceable medical device platform. Essential Job Duties Own and maintain a custom Yocto/OpenEmbedded-based Linux distribution for a medical device platform, including layer authoring, BitBake recipes, image configuration, SDK/toolchain support, and OS version upgrades. Bring up and qualify new commercial laptop hardware platforms, including Linux driver configuration, BIOS/firmware settings, secure boot enrollment, storage/display/peripheral validation, and platform compatibility testing. Maintain and harden the secure boot chain across multiple hardware platforms, including UEFI Secure Boot, GRUB2, TPM 2.0, bootloader signing, key management, and BIOS interactions. Sustain and enhance field software update and service upgrade workflows, including package validation, update orchestration support, partition management, rollback mechanisms, BIOS firmware upgrade flows, and error recovery. Debug and resolve platform-level issues such as boot failures, unexpected reboots, TPM lockouts, login screen freezes, USB/HID issues, storage issues, display/GPU issues, and software update failures. Implement and maintain platform-layer services, utilities, scripts, and APIs used by application teams, field service, manufacturing, and system diagnostics. Perform OS-level security hardening and vulnerability remediation, including CVE fixes, user/account hardening, permissions, kernel/module configuration, endpoint security integration, and required documentation. Produce and maintain engineering design documents, software change analysis artifacts, test evidence, and technical documentation in accordance with medical device quality procedures. Collaborate cross-functionally with application software, security, field service, systems engineering, hardware, manufacturing, and quality teams. Required Education, Skills & Experience Bachelor's degree with 6+ years of industry experience, or Master's degree with 4+ years of industry experience, in Computer Science, Computer Engineering, or a related engineering discipline. 4+ years of embedded Linux software engineering, with direct OS-layer development experience. Candidates MUST have hands-on experience building, customizing, debugging, and maintaining Linux-based product platforms. Deep expertise in Yocto Project / OpenEmbedded: layer authoring (meta-*), Bitbake recipes, image manifests, and SDK toolchain configuration. Proficiency in Bash shell scripting and at least one system-level language (C or C++ preferred) for platform daemons, service utilities, and installer scripts. Experience designing and implementing field software update mechanisms: package validation, partition management, rollback, and error recovery. Practical knowledge of Linux system security hardening: file permissions, user/group privilege controls, credential management, kernel module configuration, and security scanning tools. Experience managing hardware lifecycle transitions, including end-of-life risk mitigation, replacement platform qualification, and software compatibility maintenance across hardware generations. Hardware bring-up experience on x86 laptop or embedded platforms: driver configuration, peripheral debugging (USB, HID/trackpad, display adapters, storage). Familiarity with D-Bus IPC, systemd service management, and Linux log infrastructure Proficiency with Git, Jira, Bitbucket/GitHub, and Jenkins (or equivalent CI/CD toolchain). Preferred Skills & Experience Preferred Skills and Experience Deep experience with UEFI Secure Boot, GRUB2 signing, TPM 2.0, PCR policy binding, BIOS firmware interaction, or secure key-management workflows. Experience with OTA, field update, or service update frameworks for Linux-based medical, industrial, robotics, automotive, aerospace, or regulated devices. Experience with commercial laptop BIOS tools, firmware upgrade automation, hardware lifecycle management, or replacement-platform qualification. Experience integrating NVIDIA drivers, CUDA components, GPU/display stacks, or accelerated compute packages into Yocto-based Linux systems. Experience with Qt5/Qt-based Linux GUI application environments. Experience with D-Bus IPC, systemd service d
