Powerpack Engineer Level III

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.

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Current energy and data systems rely on complex logistics and outdated infrastructure.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

The turbopump is the heart of the engine and sets its performance ceiling, and in this role, you will own pieces of it outright. You are the responsible engineer for the design definition, interfaces, fabrication, build, and test performance of your hardware - ore to orbit. As you trade different designs in the design space, you will own the case that your hardware meets its requirements and define what needs to be proven by analysis, what needs to be proven on the stand, and the plan that closes both.

This is where you put your name on flight hardware.

• Bring a culture of creativity to every design challenge. Own each solution or improvement with true accountability, seeing it through to completion.

• Own the mechanical design of turbopump components and assemblies from concept through hot fire testing and flight: CAD models, design definitions, tolerances, GD&T, material and process specifications, analysis cycles, and the requirements each component must meet.

• Integrate constraints from hydro, aero, structures, secondary flow, and thermals into a single coherent design.

• Control the configuration and record pedigree for your components across build, test, and refurbishment cycles.

• Drive hardware through manufacturing and assembly: fabrication, first-article review, and nonconformance disposition.

• Independently build the verification plan for your hardware. Decide what gets proven by analysis and what gets proven on the stand, then close both.

• Ensure test readiness, author instrumentation requests, perform real-time support and data reduction for…
