Senior embedded linux platform & qt engineer

Job Summary

Stenograph is seeking an experienced Senior Embedded Linux Platform & Qt Engineer to join the team building our next-generation embedded writer platform. This role consolidates the platform and application-UI seats into a single ownership role with the full scope of both: the selected candidate will own the complete device software stack on a Linux-based embedded platform — from board support, kernel-level platform bring-up, power management, and secure boot/OTA, through the complete touchscreen application UI built against a visual design system supplied by product design. This role requires strong expertise in embedded Linux platform engineering, power management, and shipped Qt Quick/QML application development, and the discipline to carry both the platform and application layers through production release.

Key Responsibilities

Own board support package and kernel-level platform work for a Linux-based embedded device: bootloader, kernel configuration, device tree, driver integration, and build-system authorship (Yocto/Open Embedded or equivalent). Implement and debug power-management behavior including suspend/resume, wireless connectivity coexistence, and correct interaction with an always-on companion low-power domain. Implement secure boot and an A/B (fail-safe, rollback-capable) over-the-air update mechanism for the full software image, coordinated with a companion firmware update path. Instrument and support platform power-consumption measurement work feeding a system-level power budget. Own implementation of the device's touchscreen application UI using Qt Quick/QML: primary application views, settings, status/notification surfaces, and secondary/always-on display behavior including detach/failover states. Build the UI faithfully against the visual design system and interaction specification produced by product design, and work directly with the designer to resolve implementation constraints with minimal round-trips. Integrate C++ backend/business logic and platform services with the QML UI layer, including live data from the device's real-time capture and translation services. Implement UI-side behavior for connectivity, update/OTA status, and device settings flows. Establish and maintain UI test automation/coverage for the application layer. Collaborate with firmware, application, QA, and program leadership on platform-level integration, timing/latency budgets, update/rollback behavior, UI performance and responsiveness under system load, and touch-interaction quality. Participate in design and code review across both platform and application layers. Utilize modern AI-assisted development tools to accelerate development and test authoring, while applying independent engineering judgment and verification rather than trusting generated output at face value. Support the product from early architecture and UI prototyping through production release, including sitting in on user feedback/beta sessions and translating findings into implementation changes.

Required Qualifications

Bachelor's Degree in Computer Engineering, Software Engineering, Computer Science, or related field (or equivalent experience). 5+ years of professional embedded Linux development experience, including shipped touchscreen or embedded application UI work. Hands-on experience authoring and maintaining embedded Linux build-system layers (e.g., Yocto/Open Embedded or equivalent). Experience with a specific So C family at the board-support level: device tree, bootloader, kernel driver integration. Demonstrated experience debugging kernel-level power management (suspend/resume, low-power states, wireless coexistence). Strong, demonstrated experience building shipped, production Qt Quick/QML touchscreen or embedded application UIs on embedded Linux. Experience with LVGL for constrained embedded UI surfaces. Solid C++ skills and experience integrating C++ logic with a declarative UI layer. Experience building UI against a formal visual design system or design specification, rather than improvising visual design independently. Demonstrated, hands-on effectiveness with AI-assisted software engineering tools (agentic coding assistants, AI-based code review), with clear judgment about when to trust generated output and when it requires independent verification. Excellent troubleshooting and debugging skills, including hardware/software boundary issues and performance/responsiveness issues under real-time system load. Experience using Git for version control and standard issue-tracking tools for project/task management.

Preferred Qualifications

Experience with over-the-air update frameworks (A/B image update systems). Experience with heterogeneous multi-processor So Cs (application processor plus a low-power co-processor domain). Experience with embedded NPU/AI-accelerator toolchains. Prior experience specifically deploying a commercial embedded-Linux/Qt device platform. Touch UX craft and hands-on familiarity with UI test-automation frameworks for Qt/QML. Experience with secondary/always-on or dual-display device UIs. Experience participating in user/beta feedback sessions and iterating UI based on real-world use. Experience working in Agile development environments.
