Senior AI Engineer - Imitation Learning

RIVR is a Swiss robotics company pioneering Physical AI and robotic solutions to revolutionize last-mile delivery, giving 1 human the power of 1000. Through the combination of artificial neural networks and innovative robot designs with wheels and legs, RIVR aims to enhance efficiency, sustainability, and scalability in last-mile delivery. Founded as Swiss-Mile, the company rebranded to RIVR in 2025 to better reflect its mission of driving the future of intelligent robotics.
Imitation learning enables our robot to mimic "expert" behaviors, derived from human demonstrations or algorithmic strategies. By utilizing state-of-the-art generative AI and similar methods, our wheeled-legged robot can significantly enhance its autonomy and manipulation skills. In this role, you will enable robots to autonomously generate actions from demonstrations and real-time sensor data. These processes may also incorporate responses to natural language commands, further advancing the robot's skills. We are seeking an expert in imitation learning and generative AI techniques that directly produce robot behaviors, along with a deep knowledge of both supervised and self-supervised learning algorithms. If you are passionate about pushing the boundaries of AI and eager to deliver innovative solutions, we invite you to join us in shaping the future of intelligent robotics.

What you’ll be doing

• Develop cutting-edge imitation learning algorithms, such as diffusion policies, to enable robots to autonomously execute actions based on demonstrations and real-time sensor data.
• Design, test, and refine your algorithms to meet the demands of complex real-world autonomy and manipulation tasks.
• Construct a dataset for the imitation learning algorithm using human demonstrations or automated expert algorithms.
• Streamline the workflow to efficiently expand the imitation learning dataset with new tasks.
• Collaborate with the reinforcement learning team to innovate methods that leverage both simulated and real-world data.
• Implement deployment-ready code for the real robot, optimized for the robot’s computational constraints.
• Build, lead and mentor an exceptional team of software engineers.
• Provide expert guidance to product managers and executives for strategic decision-making.
• Create and maintain documentation, guidelines, and best practices to streamline knowledge sharing.

What you must have

• Master’s degree or higher in a relevant field such as Engineering, Robotics, or Machine Learning.
• A minimum of three years of industry or research experience, with PhD experience applicable.
