## About Cosmic Robotics

Our mission is to build a city on Mars. 

Cosmic-1, the first equipment in our fleet, is an autonomous robot capable of heavy-lift manipulation. Its been deployed on some of the largest solar farms in the US, more than doubling labor productivity across tens of thousands of panel installs. 

We're scaling in solar, expanding in data centers, and building lunar construction robotics under contract with NASA.

## About the role

**Senior Mechanical Engineer**

Location: San Francisco, CA (full time, in-person)

**Company Overview**

Our mission is to **build a city on Mars and accelerate the construction of critical infrastructure on 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.

**The Role**

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.

This is a rare opportunity to:

- Work on hard, meaningful problems that impact the future of infrastructure and energy.

- Collaborate with a world-class team from NASA, SpaceX, Tesla, Google, Built Robotics, and others.

- Rapidly grow, learn, and lead within a quickly scaling company.**Responsibilities**

- Own hardware components and systems such as primary and secondary structures, mechanisms, and enclosures
