Senior Embedded Linux Software Engineer — OS & Device Platform

Job Description

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/Open Embedded 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/Open Embedded-based Linux distribution for a medical device platform, including layer authoring, Bit Bake 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, boot loader 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.
• Hands‑on experience building, customizing, debugging, and maintaining Linux-based product platforms.
• Deep expertise in Yocto Project / Open Embedded: 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…
