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.
