Descripción de la vacante

Harmattan AI in France is seeking a Kernel Software Engineer to own the low-level software platform between hardware and flight applications on our ground control stations. You will work across the Linux kernel, board support and a custom Android build, taking a new product line from bring-up to mass production.

You will collaborate with hardware, electronics and mechanical engineers, ensure low-latency SBUS and MAVLink data flows, and help validate systems on real hardware through field tests.

Formación

• Master’s degree in Embedded Systems, Software Engineering, Electronics or related field.
• 3+ years of 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.

Responsabilidades

• 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.

Descripción del empleo

About UsHarmattan 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.
