About The Position

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. The Role We're looking for a DSP Software Engineer to develop the real-time signal processing algorithms that power our space-based communications and sensing systems. In this role, you'll design, implement, and optimize software that extracts, processes, and analyzes high-speed data streams in resource-constrained environments. You'll collaborate closely with FPGA, RF, avionics, and embedded software engineers to develop algorithms that enable reliable operation in one of the most challenging environments imaginable. This is an opportunity to own mission-critical software that directly impacts spacecraft performance and system capability.
