Senior Mechanical Engineer — Autonomous Construction Leader

We're building autonomous systems to accelerate the construction of renewable energy infrastructure and transform field construction. Our first product, Cosmic-1, is a fully autonomous robot designed to install solar panels 10x faster than current methods - helping us transition to a clean energy future while laying the groundwork for autonomous construction beyond Earth.

Our team combines deep expertise in robotics, AI, and construction automation. We've developed Particle AI, a physical AI engine that powers real tools in the real world, driving decision-making and adaptability across dynamic site conditions. Our Constellation platform serves as a digital twin, coordinating robotic tools, tracking work-in-progress, managing projects, and generating real-time insights for construction sites. Based in San Francisco's Dogpatch neighborhood, we're working to meet the massive demand for electricity and renewable energy targets - over 600 million solar panels need to be installed on utility-scale projects by 2030, and our technology is critical to making that happen.
