Corp., you will build the systems that control, operate, and scale our spacecraft and ground infrastructure. This includes flight software, simulation, mission control systems, and the tooling needed to test and operate hardware in real time. This is a highly ownership-driven role where you’ll work across the stack—from low-level systems interacting with hardware to higher-level services that enable mission operations. You’ll collaborate closely with hardware teams (propulsion, power, avionics) to bring up systems, validate performance, and ensure reliable operation in demanding environments.

More from the job description
Software Engineer (San Carlos, CA) 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.
