About the role
As a Fluids Analyst, you will own fluids prediction for the team — the models, the analysis, and the data that back every fluid system decision we make. You are accountable for the full lifecycle of that prediction: standing up early system models before hardware exists, sizing and trading architectures against pressure drop, flow capability, and thermal performance, then closing the loop by reducing test data and correlating it back into the models.
What they're looking for
- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, or related field
- 5+ years of experience performing fluid system analysis for flight vehicles, propulsion systems, or other high-performance hardware
- Strong fundamentals in fluid mechanics, thermodynamics, and heat transfer, including compressible flow, two-phase flow, and transient system behavior
- Experience building 1D fluid network or transient system models with tools such as Flownex, AFT (Fathom/Arrow/Impulse), EASY5, GFSSP, Simulink, or equivalent in-house codes
- Hands-on experience with commercial or open-source CFD (ANSYS Fluent, Siemens STAR-CCM+, or OpenFOAM) applied to internal flow problems
- Proficiency with Python (NumPy, pandas) or MATLAB for model development, data reduction, and automation of analysis workflows

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Current energy and data systems rely on complex logistics and outdated infrastructure.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