About Charge

Charge Robotics is a Series A startup building robots that build solar farms.

Demand for new solar projects is booming (1 ⁄ 5 of all the solar that exists in the US was installed last year!), but today’s construction companies can’t keep up due to limited labor resources.

We thought this was insane, so we started working on robots to directly address this bottleneck and speed up the world’s transition to renewables.

Charge is a fast-moving company, which means constant opportunities for learning and growth. You’ll have a large impact on the direction of our company, and will be compensated accordingly.

If you are excited to work on interesting problems with direct climate impact, you’re going to fit right in at Charge Robotics.
