Lead Mechanical Engineer, Compute Systems

Job description

**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 Current energy and data systems rely on complex logistics and outdated infrastructure.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:** The Payload Mechanical team is looking for a Lead Mechanical Engineer to act as the responsible engineer for the structural and thermal-mechanical design of our space-based compute hardware. The ideal candidate is a self-motivated expert with deep experience in high-reliability space systems, comfortable driving everything from packaging architecture and thermal trade studies to hands-on hardware integration and qualification. This role covers electronics packaging, chassis design, thermal management, and structural qualification for compute and power electronics operating in the harsh environment of Low Earth Orbit. You will lead a team of mechanical engineers and work closely with electrical, thermal, and spacecraft systems teams to deliver robust, high-performance compute flight hardware ready for orbit. Previous experience driving end-to-end mechanical development of electronics packaging or compute hardware for space or high-reliability applications in a fast-paced environment is required. **Responsibilities:** - Own the mechanical architecture of space-based compute hardware, including chassis, PCB retention, connector interfaces, and thermal management, from concept through production - Perform system-level trade studies on packaging, mass, and thermal performance to optimize compute hardware architecture - Lead and mentor a team of mechanical engineers, setting technical direction, review standards, and execution pace - Define and own interfaces and technical budgets for compute and power electronics assemblies - Drive structural and thermal analysis efforts, working with analysts to validate designs against requirements - Develop and maintain mechanical drawings, GD&T specifications, and ICDs for internal manufacture and external vendors - Define and execute mechanical integration and test plans, including environmental qualification (vibration, shock, thermal-vacuum) - Represent the mechanical team in design reviews and system-level discussions - Collaborate cross-functionally with electrical, thermal, and spacecraft teams to ensure compatibility at all mechanical and thermal interfaces **Basic Qualifications:** - Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field - 5+ years of experience in mechanical engineering for flight hardware in aerospace, defense, or high-reliability electronics programs - Demonstrated experience as the technical lead or authority on the mechanical design of electronics enclosures or compute hardware for space or high-reliability applications - Proficiency in 3D CAD (NX, Solidworks, or equivalent) and engineering drawing/GD&T - Experience with structural analysis and thermal modeling tools - Experience taking flight hardware through environmental qualification (vibration, shock, thermal-vacuum) - Strong understanding of thermal management approaches for high-power electronics in vacuum environments - Experience managing direct reports or leading a technical team **Preferred Qualifications:** - Master's degree in Mechanical or Aerospace Engineering - 8+ years of experience developing flight hardware for space or defense programs - Experience with conduction-cooled electronics packaging or cold plate design for space flight hardware - Experience with liquid cooling solutions for flight hardware - Familiarity with high-power compute or GPU hardware packaging and associated thermal constraints - Experience with radiation design considerations for electronics operating in LEO - Experience with deployable or articulating power or thermal structures - Hands-on experience with flight hardware integration and test in a lab or cleanroom environment - Prior experience as a technical lead or engineering manager on a flight program ## **Compensation and Benefits** The salary range for this position is **$150,000 - $225,000** 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 **ITAR Requirements** - *Export Control Requirement: To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR), applicants must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
