## Description

### **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.
