About this role

CesiumAstro develops out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We seek a skilled Propulsion / Turbomachinery Engineer II with experience in aerodynamic and mechanical design of radial and axial turbomachinery systems. You will design, analyze, and test critical components for propulsion systems.

Execute CFD analyses including steady, transient, and multiphase to evaluate performance of compressors, turbines, and pumps in liquid rocket engine feed systems. Perform structural and thermal FEA to ensure mechanical integrity under operational loads. Design aerodynamic flow paths and optimize turbomachinery elements using specialized software tools.

Work in a dynamic and cross-functional environment that encourages hands-on, interactive, and autonomous contributions. Collaborate across multidisciplinary teams including mechanical, aerospace, and controls engineering. Provide technical support through all phases of the product lifecycle from concept to production.

Develop test programs, analyze experimental data, and apply results to improve design iterations. Support design, optimization, and development of turbomachinery across propulsion systems. Join passionate, collaborative, energetic, and forward-thinking individuals at CesiumAstro.
