About American Turbines The power grid was built for a world that no longer exists. Centralized generation, hundred-mile transmission lines, decade-long permitting cycles. Meanwhile, demand is exploding: data centers, industrial electrification, remote operations that need megawatts yesterday and can't wait for utilities to catch up. American Turbines is designing small modular gas turbines, purpose-built for distributed power generation. Machines designed from a blank sheet to be manufactured at scale, clustered in arrays. Hundreds of units operating in parallel, dynamically matching load like a compute cluster matches demand. We are a seed-stage company backed by the investors behind SpaceX, Boom Supersonic, and Hadrian. About the Role The Junior Mechanical Engineer will help turn a running turbine core into a deployable product: the package, the structural frame, the mounts, and the mechanical systems that keep the machine fed, cooled, and serviceable in the field....
