Harmattan AI

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 GNC Engineer on the UAV team, you’ll design and develop advanced guidance, navigation, and control (GNC) solutions. From integrating and fusing sensor data to developing control laws and flight trajectories, you'll take your work from simulation to embedded implementation—and ultimately to live flight testing. RESPONSIBILITIES * Develop state-of-the-art navigation and sensor fusion algorithms for UAVs * Design and implement GNC and flight control systems * Build filtering and estimation strategies for robust and efficient flight performance * Run extensive simulations (Monte Carlo, SITL, HITL) and coverage testing * Analyze test flight data and refine algorithmic performance * Support full-stack system integration: GNSS, INS/IMU, localization, and fusion * Maintain and evolve a flight-proven flight computer across multiple UAV platforms REQUIREMENTS * Education : Engineering school or master's degree in computer science, engineering, or a related technical field * 3+ years of experience in aerospace GNC systems * Strong foundations in control theory, estimation, and sensor integration * Proficient in Python and embedded C/C++ * Experience with simulation tools (e.g., Gazebo) and version control (Git) * Familiarity with open-source autopilots (PX4, Ardupilot, Betaflight, etc.) * Hands-on electronics and integration skills: debugging, soldering, harnessing * Bonus: FPV pilot hobbyist We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.

We operate in a demanding environment where rigor, ownership, and execution are expected. ABOUT THE ROLE As a Mechanical Engineer on Harmattan AI’s Airframe team, you will design UAV platforms and subsystems in an autonomous, fast-paced environment. You will take ownership of projects from concept through to production, ensuring optimal performance, reliability, and manufacturability. RESPONSIBILITIES * Design and prototype UAV platforms and complex subsystems from scratch, ensuring the right balance between durability, efficiency, and performance. * Take full ownership of system-level constraints, including thermal management, mass budget (weight), COGS (cost), and environmental sealing (IP ratings). * Work closely with R&D teams (Electrical, Software, and Industrialisation) to ensure seamless mechanical integration of sensors, payloads, and electronics. * Conduct rigorous testing, including stress and failure analysis. Identify risks proactively and develop the necessary tools (test benches, calculation sheets, or scripts) to validate designs for operation in extreme environments. * Manage your own delivery packages and technical specifications with precision, consistently meeting or exceeding requirements under tight deadlines. * Oversee the manufacturing process by collaborating directly with suppliers and external manufacturers, with a focus on plastic injection moulding and precision machining, to ensure quality and schedule targets are achieved. * Maintain the “source of truth” through Confluence and professional 2D/3D documentation. Document all designs, test results, and production workflows to support knowledge sharing and continuous improvement. CANDIDATE REQUIREMENTS * Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field. * Proven experience designing and prototyping mechanical systems, ideally within UAVs, robotics, or defence applications. * Proficiency in CAD software (e.g., SolidWorks); experience with structural and thermal analysis tools (FEA) is a strong advantage. * Strong understanding of manufacturing processes, including high-precision machining and plastic injection moulding. * Excellent written and verbal communication skills, with the ability to clearly document complex technical concepts and lead cross-functional discussions. * Full commitment to Harmattan AI’s mission, vision, and growth plans, with a willingness to go the extra mile in pursuit of operational excellence. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
