Senior Linux Platform Engineer

Benefits

Additional Information

Primary Function of Position The Senior Linux Platform 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. The engineer is the primary owner of OS bring-up, secure boot, remote software update infrastructure, platform security hardening, and hardware bring-up for new laptop models. This is a cross-functional role requiring close collaboration with application software, security, field service, and systems engineering teams, with opportunity to stretch into application-layer features and broader platform infrastructure work as product needs evolve. Essential Job Duties Own and maintain the Yocto-based Linux OS for the procedure planning laptop, including custom BSP and application layer authoring, OS version upgrades across multiple Yocto LTS releases, kernel configuration, and Bitbake recipe maintenance. Maintain, validate, and harden the full secure boot chain (UEFI Secure Boot, GRUB2, TPM 2.0, bootloader key management) across multiple commercial laptop platforms. Sustain and enhance remote software upgrade capabilities and on-site service upgrade workflows, including software package creation and validation, update orchestration support, BIOS firmware upgrade maintenance, partition management, rollback mechanisms, and error recovery. Manage hardware lifecycle across multiple commercial laptop platforms: conduct bring-up for new models (driver configuration, secure boot enrollment, BIOS management, GPU integration) and lead end-of-life (EOL) transition planning and replacement hardware qualification. Perform security vulnerability remediation: identify and fix OS-level CVEs, integrate and validate endpoint security tooling, implement OS-level account hardening, and produce required documentation. Produce and maintain engineering design documents, software change analysis artifacts, and technical documentation per medical device quality procedures. Debug and resolve platform-level field issues including unexpected reboots, TPM lockouts, boot failures, login screen freezes, and USB-related defects. Support software application teams with platform-layer APIs (D-Bus services, power monitoring, log rotation, hardware interface utilities) as needed. 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. 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 Proficiency in Python for build/test automation, scripting, and tooling in embedded Linux workflows. Experience with commercial laptop BIOS tools and BIOS firmware upgrade automation. Strong knowledge of Linux secure boot: UEFI Secure Boot, GRUB2 configuration and signing, TPM 2.0, PCR policy binding, and BIOS firmware interaction. Familiarity with NVIDIA CUDA integration in Yocto-based Linux (driver packaging, CUDA version management, multi-GPU laptop bring-up). Working knowledge of Linux disk and partition management, including partition table schemes, block-level encryption, and bootloader partition layouts. Familiarity with Linux networking stack configuration, including wireless networking and firewall management. Background in cryptographic key management: PKI, signing infrastructure, and secure key rotation workflows. Experience integrating endpoint security agents (EDR, antivirus) in embedded Linux environments. Prior experience with OTA update frameworks for Lin
