Propulsion Engineering
Cowboy Space
Propulsion Engineering Cowboy Space Corp. is building the infrastructure to power and connect the orbital economy. Our satellites operate in Low Earth Orbit to collect sunlight and enable a new class of capabilities—from powering on-orbit compute, to transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit compute to delivering secure, high-bandwidth optical data. By rethinking how energy and data are generated and distributed in space, we’re unlocking entirely new ways to operate both in orbit and on Earth. Founded in 2024 by Baiju Bhatt (co-founder of Robinhood), Cowboy Space Corp. is backed by leading investors and built by a team from top aerospace and defense organizations. We’re moving quickly to solve complex technical challenges and build a new category of space infrastructure. About the Role We are hiring across multiple propulsion disciplines and are looking for engineers with experience designing, analyzing, building, testing, or integrating propulsion systems for aerospace applications. This is a broad opportunity for propulsion engineers who thrive in highly technical, hands‑on environments and want meaningful ownership over flight‑critical hardware.
