Fluid System Engineer ll - Helium

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We are developing 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 and involves developing and sustaining the infrastructure needed to transport crew and cargo from Earth to the lunar surface.

A successful candidate will understand fluid systems, fluid dynamics, and compressible flow for space vehicles.

The position works under a senior engineer accountable for helium storage and distribution within the Gas and Thrusters (G&T) team for a Lunar Permanence Vehicle. Responsibilities include design, analysis, procurement, installation, and testing of helium subsystem components and sub‑assembly systems. You will manage valves, bottles, filters, sensors, piping, and other fluid equipment, sizing, material selection, and structural analysis under pressure, vibration, fracture, and fatigue.

Suppliers or internal Blue Origin groups will be consulted for component procurement, fabrication, and installation, and you will also manage the project plan, cost, and schedule for your sub‑assembly. The role will be on the ground floor of our Transfer Stage Vehicle at the Rocket Park Facility in Florida. Passion for our mission and vision is required!
