An autonomous navigation developer designs, implements, and tests software for autonomous vehicles or robots. They create algorithms for perception, localization, path planning, and control, enabling machines to navigate independently in different environments. Developers work with sensor data like radar, lidar, or camera inputs, and apply machine learning techniques to enhance the system's adaptability and decision-making. They also ensure the system's compliance with safety standards. Their role involves extensive collaboration with other software engineers, robotics experts, and data scientists, continuously iterating on the system to improve its performance, reliability, and efficiency.
