Senior Mechanical Engineer

Senior Mechanical Engineer at Cosmic Robotics – San Francisco, CA (full time, in-person).

Our mission is to accelerate the construction of critical infrastructure on Earth while pioneering technologies to enable humanity to build beyond Earth. Starting with Cosmic-1 – a system that installs solar panels 10x faster than today’s methods, helping us transition to a clean energy future and laying the groundwork for the future of autonomous construction.

As a Senior Mechanical Engineer, you will own a critical Cosmic-1 subsystem and lead development from concept to deployment. As a core member of the team, you will help define the era of autonomous construction.
