About The Position

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 you will be part of the 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 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 fluids engineer to help design, build, and commission them. As part of a hardworking, cross-functional team — working alongside the Senior Marine Fluids Engineer, the Senior Marine Electrical Engineer, the Technical Lead (Analyst / Naval Architect), the Marine I&C Engineer, a team of Project Construction Managers, and the Recovery Offshore Operations Engineer — you will support 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. Working under the technical direction of the Senior Marine Fluids Engineer, you will contribute to nitrogen generation and distribution system development, marine piping design, system analysis, fabrication and installation oversight at shipyard locations, and commissioning activities. This role offers an exceptional opportunity to develop deep expertise in both marine and cryogenic fluids engineering on a program that sits at the cutting edge of both industries. If you are passionate about fluid systems and want to apply that passion to building a vessel that will bring rockets home from the ocean, this is the role for you. We are looking for someone eager to apply their growing technical expertise, strong work ethic, and commitment to quality to positively impact safe human spaceflight. Passion for our mission and vision is required!
