Senior Embedded Linux / BSP Engineer (Smart Appliance / IoT)

We are developing a next-generation, smart kitchen appliance featuring on-edge AI food recognition, a rich touchscreen user interface, and Wi-Fi cloud and Bluetooth connectivity. We are seeking a Senior Embedded Linux / BSP Engineer to own the foundational operating system development.

In this role, you will build, secure, and maintain a highly optimized, production-ready Linux distribution using the Yocto Project or other build environments. You will act as the critical bridge between our custom hardware and our application software layers, ensuring safety, reliability, and seamless hardware-software integration.

Core Responsibilities

• BSP & Custom Distribution Development: Design, configure, and maintain a custom, lightweight Embedded Linux distribution utilizing the Yocto Project.
• Kernel & Bootloader Customization: Optimize and patch U-Boot and the Linux Kernel. Write and maintain Device Trees (.dts/.dtsi) to configure pin multiplexing (pinmux) for display, camera, and peripheral interfaces.
• Peripheral Driver Integration: Configure and validate Linux drivers for critical hardware subsystems, specifically MIPI-CSI camera sensors, touchscreens, Wi-Fi/Bluetooth modules, and high-speed storage.
• Processor Inter-Communication: Implement and harden a reliable, secure communication protocol (UART/SPI) between the  Linux host and a secondary safety microcontroller.
• System Hardening & Security: Implement Secure Boot, encrypted storage, firewalls, and user privilege separation to satisfy consumer appliance security standards.
• OTA Infrastructure: Architect and integrate a robust, fail-safe Over-the-Air (OTA) update system  capable of dual-partition system recovery.
• Production Flashing: Collaborate with hardware and factory teams to create minimal, stable manufacturing images for high-volume automated flashing.

Required Technical Qualifications

• 5+ years of experience in Embedded Linux development with a track record of shipping commercial, mass-production IoT or consumer electronics devices.
• Expert-level proficiency with the Yocto Project (writing custom layers, BitBake recipes, .conf files, and managing dependencies).
• Strong capability to read hardware schematics and collaborate closely with electrical engineers to bring up new hardware revisions.
• Deep knowledge of Linux kernel driver architecture and low-level communication buses (I2C, SPI, UART, PWM, MIPI-CSI).
• Proficiency in C, C++, Python, and Shell scripting.

Preferred Qualifications

• Experience integrating machine learning deployment frameworks (TensorFlow Lite, ONNX Runtime).
• Familiarity with appliance safety certifications (e.g., UL 197 / UL 60730) and regulatory compliance (FCC/CE).
