## About the role

The primary structure is the plant. It carries the hot loop, the power electronics, and the connection to the well; it survives the lift, the splash zone, the transit, and the landing on an active hydrothermal field 1-3 km down; and then it stays there for years in seawater at 100-300 bar. We design, build, test, and deploy it. Found on 1752vc Careers, the job board for startup and VC roles.
