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 a Software Engineer within the Ground Control Systems (GCS) team, you will play a central role in developing Harmattan AI’s new range of drone controllers — high-performance, Android-based control stations designed for professional UAV operations. You will adapt and extend the open-source QGroundControl platform (C++/Qt) to integrate seamlessly with our proprietary hardware, adding new features and ensuring reliability, performance, and scalability across missions.

Responsibilities

  • App Development: Design, develop, and optimize our QGroundControl-based application using C++ and Qt.

  • Hardware Integration: Adapt the app interface with physical controls (joysticks, buttons, switches, touchscreen) for a cohesive operator experience.

  • Feature Implementation: Translate user needs and mission requirements into new functionalities and UX/UI improvements.

  • Platform Maintenance: Port and maintain the app across Android versions, ensuring performance, compatibility, and security.

  • Deployment: Manage app updates and releases across our device fleet.

  • Collaboration: Work closely with embedded and electronics teams to ensure smooth hardware/software integration and with QA for field validation.

Candidate Requirements

  • Master’s degree in Software Engineering or related field.

  • 3+ years of experience in software development: C++ and Qt for desktop or embedded applications.

  • Experience with Android development (Java or C++/NDK).

  • Familiarity with UX/UI design principles and cross-platform app optimization.

  • Experience in robotics or drones environments is a strong plus.

  • Knowledge of MAVLink, PX4, or ground control systems is an advantage.

  • English proficiency (reading and writing technical documentation).

  • Versatile, autonomous, and eager to learn in a fast-evolving technical environment.

Location and Commitments

  • Contract Type: Permanent contract (CDI)

  • Work Schedule: Full-time

  • Availability: ASAP

  • Location: Paris

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