About the Company 

Mujin develops and sells "intelligent robot controllers" with the goal of building a common platform for industrial robots. Conventional robots are suitable for automating repetitive work, but traditionally they've been hard to install in environments where products and surroundings change. Most robots have complex settings that are hard to change for each use case. Mujin's tech solves this problem using technology called motion planning. It allows them to provide solutions that replace heavy but simple work done by humans with automation by robots. The technology is used primarily for logistics and manufacturing applications.


  • We work in a fast-paced, agile environment where we constantly collaborate, review ideas amongst peers, and test proposed solutions. We encourage continuous learning and brainstorming within our teams. We are focused on solving real-world problems and your contributions are deployed at an amazingly fast pace to empower industrial robots to perform tasks that were previously impossible.
