NewDirector of Engineering: Deployables (micro-satellites) Space KineticDirector of Engineering: Deployables (micro-satellites)El Segundo, California$195,000–$220,000 / yearSpace Kinetic is a dual use space technology startup building a completely new architecture for space operations – one that brings the advantages of proliferated drone technology (low-cost, operationally flexible, attritable, distributed) to space missions while reducing the ecosystem's reliance on consumable fuel. Our goal is to move away from one-to-one space architectures – where each satellite in a constellation has one (or a small number of) primary payloads attached to the bus – and unlock a "one-to-many" system, where each satellite has a large number of payloads which can be deployed from their host spacecraft at high velocities without firing a thruster.
