Machine Learning Engineer

Postmates, San Francisco or Vancouver

Delivery from all your favorites places on-demand

At Postmates X, we are reimagining how things move in cities. Serve, our personable sidewalk delivery robot, is our vision for the future of delivery. It’s designed to take deliveries away from congested streets and onto underutilized alleys and sidewalks, to save energy, reduce emissions, reduce traffic, and make deliveries faster and cheaper. Why move two-pound burritos with two-ton cars?

Serve has been years in the making and has already done thousands of customer deliveries.


We are tech industry veterans in software, hardware and design who are pooling our individual talents together to build a legacy. Our team is inclusive, agile, and driven by a common purpose. We are solving real-world problems with machine learning, computer vision, and robotics, with a mindful eye towards the end-to-end user experience. By joining our team, you will help create the first robotic helpers entering our cities: moving alongside us and running our errands!


In this role you will work closely with the other robotics engineers to design and develop deep learning / neural network strategies for autonomous vehicles. We don’t require you to have deep experience in industrial/academic research, but we hope you have experience and knowledge in machine learning / deep learning algorithms, strong understanding of computer systems, and solid software design and coding skills.
