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Current energy and data systems rely on complex logistics and outdated infrastructure.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

We are looking for a Senior Spacecraft Engineer to help design, build, and integrate the core systems that power our satellite platform. You will work across spacecraft subsystems—including structures, power, thermal, and avionics—to develop reliable, high-performance systems that operate in the harsh environment of space.

This is a high-growth role with the opportunity to gain ownership quickly and work closely with a multidisciplinary team spanning software, electrical, optical, and mechanical engineering.

• Design, develop, and integrate spacecraft subsystems, including structures, power, thermal, and avionics

• Own components of the spacecraft architecture, from early design through integration and test

• Perform system-level trade studies to optimize performance, mass, power, and reliability

• Support development of spacecraft layouts, CAD models, and system schematics

• Plan and execute integration and test campaigns, including subsystem and full vehicle testing

• Develop and maintain technical documentation, including requirements, interface control documents (ICDs), and test plans

• Collaborate cross-functionally with software, electrical, optical, and GNC teams to ensure system-level performance

• Support environmental testing and validation, including thermal-vacuum, vibration, and EMI/EMC testing

• Participate in design reviews (PDR, CDR) and contribute to system-level decision making

• 3–5 years of experience in spacecraft, aerospace, or mechanical, or electrical engineering (internships and relevant projects count)

• Bachelor’s degree in…
