Senior Embedded Linux Software Engineer - OS & Device Platform

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.

- 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.

- 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).

- 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 design, platform daemons, diagnostics utilities, or hardware abstraction services. - Knowledge of Linux disk and partition management, including boot partitions, recovery partitions, encryption, and block-device troubleshooting. - Familiarity with Linux networking configuration, wireless networking, firewall management, and endpoint security agents. - Background in regulated product development, medical device software lifecycle, IEC 62304, FDA software guidance, or equivalent safety/quality processes.
