Fluids Systems Designer - Lunar Permanence

Application close date:

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low‑cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

This role is part of the Lunar Permanence business unit, which develops Blue Origin’s Blue Moon landers and related products. To further Blue Origin's mission of millions of people living and working in space for the benefit of Earth, we are building sustainable infrastructure for our transport of crew and cargo from Earth to the lunar surface.

In this role you will be the Fluids Systems Design Lead, to design and deliver the fluids systems that supply our main propulsion for the Cargo Lunar Lander. Scope includes the complete life cycle from system definition, interfaces, conceptual design, detailed design, component development, assembly, verification, and operations. You will lead cross-functional trade studies, run integrated analyses, and define interfaces that impact the design and integration of the spacecraft.

A successful candidate will understand fluid systems, components, fluid dynamics, and compressible flow for space vehicles. You should expect that this foundational part of our vision will require your excellent communication and teamwork.

• Build and maintain transient fluids simulation models of the subsystem in the spacecraft primarily using Matlab.
• Optimize hardware configuration, mission conops and control logic to drive overall vehicle performance.
• Drive requirements definition and test planning to validate system performance in relevant environments.
• Lead trade studies across the vehicle in a multi‑functional capacity representing the Fluids Subsystem.
• Project planning for iterative design cycles and integrated schedules leading to hardware delivery.
• Support internal and external gated reviews, documenting design maturation.

• B.S. degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• Demonstrated experience in fluids design and analysis.
• Strong understanding of Fluid Mechanics, Heat Transfer and Thermodynamics.
• Strong ability and desire to analyze complex systems and deliver solutions to problems passionate about achieving specific outcomes.
• Highly knowledgeable of systems engineering practices, integration processes, and mission/safety critical systems.
• Excellent verbal, written, and graphical communication skills.
• Ability to work collaboratively in a fast paced, dynamic work environment.

• Prior experience on spacecraft fluid systems.
• CFD experience (ANSYS Fluent and FLOW3D preferred).
• Knowledge of standard installation and fabrication methods of fluid systems (tube stock, fittings, connections, fasteners, welding, etc.).
• Experience with hydrogen and oxygen systems.
• Direct experience providing feedback for design iteration and optimization.
• Process automation experience using scripting (VBA, Matlab, Python, FORTRAN, etc.).
