Position

This role involves designing, developing, and implementing next-generation targeting algorithms for autonomous drones. The ideal candidate will be a specialist in control strategies for agile aerial platforms.

Main Responsibilities

1. Algorithm Development: Design and implement advanced guidance, navigation, and control (GNC) algorithms, focusing on skid-to-turn (STT) control for high-maneuverability and precise targeting.
2. Behavioral Logic: Develop complex mission logic, tactical decisions, and targeting sequences using Behavior Trees.
3. Prototyping & Simulation: Rapidly prototype, simulate, and validate algorithms using Python and scientific libraries (NumPy, SciPy, Matplotlib).
4. System Integration: Integrate, test, and deploy GNC software on hardware-in-the-loop (HIL) testbeds and flight hardware with PX4 autopilot stack.
5. Performance Analysis: Analyze simulation and flight data to refine algorithm robustness and reliability in dynamic environments.

Requirements

1. Educational Background: Degree in Aerospace Engineering, Robotics, Computer Science, or related field; Master’s or PhD preferred.
2. STT Specialism: Deep knowledge of skid-to-turn guidance and control, including kinematics and control laws such as lateral acceleration commands.
3. Python Proficiency: Expert-level skills in Python for algorithm development, modeling, and data analysis.
4. Behavior Trees Expertise: Experience designing and debugging complex autonomous behaviors with Behavior Trees.
5. PX4 Experience: Hands-on experience with PX4 flight control stack, including architecture, modules, and simulation tools (SITL/HIL).
6. Core GNC Knowledge: Strong foundation in control theory, vehicle dynamics, state estimation (Kalman filters), and navigation principles.
