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 Blue Origin Operations, which is comprised of Integrated Supply Chain, Test Operations, Safety, Quality, and Mission Assurance. This includes Manufacturing and Supply Chain support across all Blue Origin facilities.

As part of a hardworking team of specialists, technicians, and engineers (use as appropriate), you will be part of a Blue Origin team responsible for constructing a new class of marine vessel purpose-built for one of the most ambitious missions in the history of spaceflight: the at-sea recovery and return of orbital-class rocket boosters. Recovering an orbital-class first stage at sea demands more than a conventional ship — it requires purpose-designed fluid systems capable of generating, storing, and delivering gaseous nitrogen (GN2) for booster safing and inerting operations in a dynamic offshore environment.

The cryogenic and pneumatic systems aboard this vessel will be unlike anything that has gone to sea before, and we need a senior fluids engineer to own them.

As part of a dedicated, cross-functional team — working alongside the Senior Marine Electrical Engineer, the Technical Lead (Analyst / Naval Architect), the Marine I&C Engineer, the Marine Fluids Engineer, a team of Project Construction Managers — you will own the design, analysis, testing, and implementation of cryogenic, pneumatic, and fluid systems for Blue Origin's marine recovery vessels, including a purpose-built new construction vessel.

Your scope will include nitrogen generation and distribution systems, high-pressure pneumatic systems, cryogenic storage and vaporization equipment, marine piping systems, thermal management, environmental control systems, and recovery-specific fluid interfaces. You will define fluid system architecture, develop piping and instrumentation diagrams (P&IDs), perform system analyses, oversee fabrication and installation at shipyard locations, and lead commissioning and acceptance testing through vessel delivery.

In this role, you will provide technical mentorship and direction to the Marine Fluids Engineer and coordinate closely with the Marine I&C Engineer on instrumentation and control interfaces for fluid systems. This is a rare opportunity to design and commission the cryogenic and fluid systems of a vessel that will bring rockets home from the ocean. We are looking for someone to apply their technical expertise, leadership skills, and commitment to quality to positively impact safe human spaceflight.

Passion for our mission and vision is required!

• Own the design, analysis, and engineering of cryogenic, pneumatic, and fluid systems for new vessel construction and fleet sustainment, including nitrogen generation and GN2 distribution systems
• Develop and maintain piping and instrumentation diagrams (P&IDs), process flow diagrams (PFDs), and system schematics for marine fluid systems
• Perform fluid system analyses including pipe sizing, pressure drop calculations, thermal analysis, flow modeling, and system transient simulations using relevant engineering tools
• Define system architecture and develop technical specifications for cryogenic storage, vaporization, and distribution equipment suited for marine environments
• Develop and validate models of fluid systems using relevant software tools (e.g., AFT Fathom/Arrow, Sinda Fluint, Simulink, MATLAB, or equivalent)
• Design and specify marine piping systems in accordance with ASME B31.1, ASME B31.3, ABS Rules, USCG CFRs, and other applicable marine standards
• Specify fluid system components including valves, regulators, pumps, heat…
