Battery Test Engineer

About the role

We’re building humanoid robots that work in homes, handling chores and tasks to give people more free time. Our mission is ambitious, but so is our team. We’ve been at this since 2014 and are ready to tackle the hard work ahead. NEO is our flagship robot, designed to move, learn, and work alongside families. We’re not just talking about it - we’re shipping it. Join us if you’re inspired by this challenge and want to make a difference.
