Who we are
We are an early-stage robotics startup based in San Francisco. We design, build, and operate autonomous urban delivery robots. In San Francisco alone, hundreds of thousands of packages are delivered every day. Over half of the world’s population lives in cities at least this big. Robotic delivery will improve reliability and drastically reduce the cost of delivery, touching the lives of billions of people and ultimately transforming how the world works. Our team is small and we’re moving lightning fast to create the world’s first fleet of autonomous delivery robots to solve this Earth-scale problem.

What you’ll be doing

Robots delivering packages in a city will encounter every environment imaginable. From people and cars, to traffic cones and broken sidewalks, the robot must operate competently and safely throughout the day. One of the fundamental challenges at Marble is to develop perception and reasoning that can understand the scene and environment surrounding the robot. At Marble you will join a team of passionate scientists and engineers building a highly accurate and real-time perception solution to address these challenges.
