About the company
About Us:
Foundation is developing the future of general purpose robotics with the goal to address the labor shortage.
Our mission is to create advanced robots that can operate in complex environments, reducing human risk in conflict zones and enhancing efficiency in labor-intensive industries. We are on the lookout for extraordinary engineers and scientists to join our team. Your previous experience in robotics isn’t a prerequisite — it’s your talent and determination that truly count. We expect that many of our team members will bring diverse perspectives from various industries and fields. We are looking for individuals with a proven record of exceptional ability and a history of creating things that work.
Our Culture:
We like to be frank and honest about who we are, so that people can decide for themselves if this is a culture they resonate with. Please read more about our culture here:https://foundation.bot/culture.
Who should join:
•
You like working in person with a team in San Francisco.
•
You deeply believe that this is the most important mission for humanity and needs to happen yesterday.
•
You are highly technical - regardless of the role you are in. We are building technology; you need to understand technology well.
•
You care about aesthetics and design inside out. If it’s not the best product ever, it bothers you, and you need to “fix” it.
•
You don’t need someone to motivate you; you get things done.
