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. We are looking for a fluids design engineer to help craft the gas systems for the Lunar Transfer Stage spacecraft. Work will include the complete life cycle of the sub-assembly from definition, interfaces, conceptual design, detailed design, component development, assembly, verification, and operations. This position goes from initial design, to analyzing, to getting hardware, launching, and operating in space. A successful candidate will understand fluid systems, components, fluid dynamics, and compressible flow for space vehicles. The position will work under a lead engineer accountable for gas and thruster systems. You will be responsible for analyzing a gas systems that support our gas distribution, gas storage, and RCS thruster assemblies. The position will be responsible for valves, pumps, heat exchangers, sensors, piping and other fluids equipment for this portion of the gas subsystem. Our team will size, select materials, and analyze components for structural integrity due to pressure, vibration, fracture, fatigue, etc. You will work with suppliers or Blue Origin internal groups to identify components and support procurement, fabrication, and installation. You will also manage the project plan for various hardware including cost and schedule for your sub-assembly. The position will work directly on our Transfer Stage Vehicle within the Lunar Permanence Business Unit.
