ABOUT US

Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.

Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.

About the Role

As Kernel Software Engineer, you own the low-level software platform that sits between our hardware and the flight application on our ground control stations. You work across the Linux kernel, board support and a custom Android build, so that every control, display and data link works reliably in the field. You are the bridge between our hardware and application teams, taking a new product line from board bring-up to mass production.

Responsibilities

  • Bring up, configure and maintain the Linux kernel on our hardware, including device tree, drivers and security patches.
  • Customize and maintain our Android build, covering system services, permissions, boot sequence and OTA updates.
  • Integrate controls, display, touch, battery and radio modules, and expose them cleanly to the application layer.
  • Ensure robust, low-latency SBUS and MAVLink data flows between the controller, the radio and the 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 your work in real conditions.

Candidate 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.

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
