About Cowboy Space Corp: Mission Cowboy Space Corporation is solving the global energy crisis by building the infrastructure for abundant, resilient space-based solar energy. We are tackling one of humanity’s most complex engineering challenges with a world-class team dedicated to delivering a revolutionary power platform. Cowboy Space Corporation is transforming how civilization powers, computes and connects - from orbit to Earth. Background Cowboy Space Corporation is building the infrastructure to power and connect the orbital economy. Our modular, scalable satellites collect sunlight in Low Earth Orbit to enable multiple integrated applications: transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit high-performance computing clusters (GPU/TPU), and providing secure, high bandwidth optical data transport. Current energy and data systems rely on complex logistics and outdated infrastructure. Cowboy Space Corporation overcomes these challenges by enabling direct, on-demand, secure, and scalable energy distribution and data processing from space. This will revolutionize how we operate in orbit and on Earth, supporting the rapidly expanding space industrial base, ISAM (In-Space Servicing, Assembly, and Manufacturing) operations, remote regions, and military bases. Baiju Bhatt founded Cowboy Space Corporation in 2024. Inspired by his father’s work with NASA Langley Research Center, Baiju earned his B.S. in Physics and M.S. in Mathematics at Stanford before co-founding Robinhood, now a public company that has helped over 20 million Americans access the financial system. Cowboy Space Corporation has raised ~$365 million from Index Ventures, Interlagos, Construct Ventures, Breakthrough Energy Ventures, Andreessen Horowitz, NEA, and others. This is an ambitious mission that demands extraordinary talent. Cowboy Space Corporation’s team has worked at places like SpaceX, Blue Origin, Stoke Space, Astranis and NASA, and is based in San Carlos, CA. If you're ready to solve complex technical challenges and help build the most important energy company in the world, we want to hear from you. Location: San Carlos, CA or Kent, WA (on-site) The Role We're looking for a Senior Flight Software Engineer to own the software that flies on our spacecraft. You'll be responsible for the payload flight software—written in Rust—spanning attitude and pointing state machines, on-board command handling, and telemetry and data storage. Today this work is distributed across several engineers; we need a senior technical owner to unify the architecture, set the patterns and conventions the team builds on, and drive the software toward a near-term on-orbit demonstration. Responsibilities • Serve as the technical lead and owner for payload flight software, from architecture through on-orbit operations • Design, develop, and test flight software in Rust for attitude and pointing state machines, command handling, and telemetry/data storage • Define the software architecture, coding patterns, and conventions adopted across the flight software team • Establish and uphold the bar for flight-quality software: determinism, fault tolerance, testability, and safe behavior under failure • Design and implement fault detection, isolation, and recovery (FDIR) behaviors at the software level • Build and maintain automated test infrastructure, including simulation and hardware-in-the-loop (HIL) testing • Collaborate closely with GNC, avionics, electrical, and systems engineers to define interfaces and system behavior • Support spacecraft integration, environmental test campaigns, and launch and early-orbit operations • Investigate anomalies across hardware/software boundaries, perform root cause analysis, and drive fixes to closure • Mentor engineers on the team and review designs and code to raise overall software quality • Help drive the team toward a near-term on-orbit demonstration, making pragmatic scope and risk tradeoffs along the way Basic Qualifications • 5+ years of experience (or equivalent practical experience) developing flight software or software for other high-reliability, safety-critical systems • Experience with software that has flown on orbit, or equivalent deployment experience demonstrating judgment about what flight-quality software requires • Strong systems programming skills in Rust, C, or C++, with willingness to work primarily in Rust • Experience with real-time and embedded systems, including resource-constrained and fault-tolerant designs • Experience designing and implementing state machines, command/telemetry handling, or similar spacecraft software functions • Experience with hardware/software integration and testing on real hardware • Demonstrated ability to lead technically: setting architecture, establishing conventions, and mentoring other engineers Preferred Qualifications • Bachelor's or advanced degree in Computer Science, Computer Engineering, Aerospace Engineering, or a related field • Prior experience as a technical lead or architect for a spacecraft flight software effort • Production Rust experience, particularly in embedded or systems contexts • Experience with attitude determination and control or pointing systems from the software side • Experience with FDIR design, redundancy management, and autonomous fault response • Experience building simulation, software-in-the-loop, and hardware-in-the-loop test environments • Experience supporting launch, commissioning, and on-orbit operations, including anomaly investigation • Familiarity with radiation effects and other space-environment considerations for software design • Experience thriving in fast-paced, high-ownership startup environments with rapid iteration cycles Compensation and Benefits: The salary range for this position is $200,000 – $250,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity. • Equity in Cow
