About the role
This is a high ownership role on a fast moving team! You will own the hydrodynamic design of the rocket engine's turbopumps: driving the engine- and vehicle-level design trades, predicting head, flow, efficiency, and suction margin across the operating box, following the hardware from concept through build, and proving its performance on the test stand. This includes inducers, impellers, diffusers and volutes, inlet and discharge flowpaths, the internal leakage and cavity flow network, and the axial thrust balance.
What they're looking for
- Bachelor’s degree in Aerospace, Mechanical, or related engineering field
- 12+ years of experience in turbomachinery hydrodynamic or aerodynamic design and analysis for flight hardware or high-performance rotating machinery
- Experience with pump sizing, specific speed and suction specific speed selection, blade and passage geometry definition, and material selection for pumped-fluid compatibility
- Experience with secondary flow and axial thrust analysis—leakage and cavity flow networks, balance piston, thrust piston, and wear ring sizing, seal and bearing coolant circuits, and net thrust balance across the operating box
- Hands-on experience taking rotating hardware from design through build and test
- Experience with liquid cryogenic rocket engine turbopumps or reusable propulsion systems

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Current energy and data systems rely on complex logistics and outdated infrastructure.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