About the Role

As Kernel Software Engineer, you will own the low-level software platform that interfaces between hardware and flight applications on ground control stations. You will work across the Linux kernel, board support, and a custom Android build to ensure reliable operation of controls, displays, and data links in the field. This role serves as the bridge between hardware and application teams, guiding new product lines from board bring-up to mass production.

Responsibilities

  • Bring up, configure, and maintain the Linux kernel on hardware, including device tree, drivers, and security patches.
  • Customize and maintain the Android build, covering system services, permissions, boot sequence, and OTA updates.
  • Integrate controls, display, touch, battery, and radio modules, exposing them cleanly to the application layer.
  • Ensure robust, low-latency SBUS and MAVLink data flows between the controller, radio, and drone.
  • Debug hardware and software issues alongside electronics and mechanical engineers using oscilloscopes, logic analyzers, and UART/JTAG.
  • Define flashing, provisioning, factory test, and release procedures with the production team.
  • Work with QGroundControl engineers and QA to validate system behavior on real hardware.
  • Join field tests and flight sessions to validate work in real conditions.

Requirements

  • Master’s degree in Embedded Systems, Software Engineering, Electronics, or a related field.
  • 3+ years of experience in embedded software development.
  • Strong command of the Linux kernel (configuration, device tree, drivers, debugging) and of C; C++ is a plus.
  • Hands-on background customizing AOSP, from HALs and system services to the build system.
  • Comfortable at the hardware boundary: UART, SPI, I2C, GPIO, USB, display and touch controllers.
  • Exposure to drones or robotics, including MAVLink or PX4/ArduPilot, is a plus.
  • Hands-on, autonomous, and pragmatic with curiosity about hardware and the ability to learn quickly.
  • Professional English for technical documentation and international collaboration.
