Senior Software Engineer

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 Current energy and data systems rely on complex logistics and outdated infrastructure.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.

About the Role: We are looking for a Software Engineer to help build critical systems that power our space-based compute platform. You will work across the stack—from flight and mission software to ground systems and simulation tools—contributing to software that operates in highly constrained, high-reliability environments. This is a high-growth role with the opportunity to gain ownership quickly and work closely with experienced engineers across hardware and software.

Responsibilities:

• Design, develop, and rigorously test high-reliability, low-latency flight software for our space-based compute platform and satellite subsystems.

• Implement and maintain critical mission software for on-orbit operation, including command and data handling (C&DH), fault detection, isolation, and recovery (FDIR), and secure communications.

• Work across the stack from low-level embedded systems to higher-level mission logic, utilizing systems-level languages (C++, Rust, Python).

• Develop software for ground systems, simulation environments, and hardware-in-the-loop testing to support integration, validation, and on-orbit operations.

• Collaborate closely with cross-functional teams, including hardware, GNC (Guidance, Navigation, and Control), and constellation operations, to define and implement software interfaces and ensure seamless system-level functionality.

• Maintain detailed technical documentation, including software design documents, interface control documents, and comprehensive test plans.

• Participate in code reviews, design reviews, and implement continuous integration/continuous deployment (CI/CD) pipelines to ensure the robustness and safe deployment of flight and ground software.

Basic Qualifications:

• 5+ years of experience in software engineering (internships and relevant projects count)

• Bachelor’s Degree in Computer Science or related field

• Proficiency in at least one systems-level language (C++, Python, or Rust)

• Exposure to one or more of the following:

• Embedded systems

• Distributed systems

• Robotics or autonomous systems

• Aerospace or hardware-adjacent software

• Strong fundamentals in data structures, algorithms, and system design basics

• Eagerness to learn and operate in a fast-paced, ambiguous environment

Preferred Qualifications:

• Proven experience working with real-time systems, multithreading, or concurrency in production environments

• Deep familiarity with Linux systems, including debugging, profiling, and performance tuning

• Experience building or operating distributed systems or networked applications (e.g., TCP/IP, sockets, or service communication)

• Experience with simulation environments or software interacting with physical systems (robotics, aerospace, automotive)

• Exposure to control systems, GNC, or autonomy stacks in a practical setting (not just academic)

• Experience working on high-reliability or safety-critical systems with strong testing and validation practices

• Experience designing or maintaining CI/CD pipelines for complex systems (including automated testing, integration with hardware or simulation environments, and safe deployment practices)

Compensation and Benefits The salary range for this position is $150,000 – $200,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity.

• Equity in Cowboy Space Corp.

• Employees and their eligible dependents may enroll in medical, dental, and vision insurance

• 401(k) retirement savings plan

• Paid time off

• 10 paid holidays per calendar year

• Paid parental leave

• Relocation assistance if applicable

• Daily lunch in the office and a fully stocked kitchen with beverages and snacks
