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. Responsibilities: - Own firmware development for spacecraft subsystems from concept through on-orbit operations - Design, develop, and debug embedded firmware for microcontrollers, FPGAs, and custom hardware platforms - Implement low-level drivers, communication protocols (SPI, I2C, UART, CAN), and real-time control systems - Develop firmware for power management, avionics interfaces, sensors, and actuator control - Build robust, fault-tolerant systems with attention to reliability, determinism, and performance under constrained environments - Support board bring-up, hardware integration, and hardware-in-the-loop (HIL) testing - Develop automated test frameworks and validation tools for embedded systems - Collaborate closely with electrical, avionics, and software teams to define system architecture and interfaces - Investigate anomalies, perform root cause analysis, and implement
