Job summary

Blue Origin in the Lunar Permanence division seeks a Liquid Systems Responsible Engineer with cryogenic fluids experience and a manufacturing mindset. You will support hardware ownership on cryogenic propellant management components and help translate requirements into producible processes for fabrication, assembly, and qualification.

Responsibilities span design support, shop-floor troubleshooting, DFx input, supplier coordination, and process documentation while aligning with AS9100/ISO 9001

Qualifications

• B.S. in Aerospace Engineering, Mechanical Engineering, Manufacturing Engineering, Physics, or related technical field.
• 5+ years of experience in cryogenic fluids and mechanical systems/components, and/or in a manufacturing, industrial, or process engineering role.
• Experience supporting the development, integration, or certification of aerospace systems for flight.
• Hands-on experience with fluid/gas components: solenoid valves, directional valves, manifolds, regulators, pressure vessels, and instrumentation.
• Experience contributing to DFM/DFA input on hardware designs and translating requirements into manufacturing processes.
• Experience with Cryogenic Fluid Management techniques and technologies.
• Experience creating clear, English-language work instructions and manufacturing documentation.
• Ability to work effectively in a fast-paced, dynamic environment spanning both design support and shop floor execution.
• Strong verbal, written, and graphical communication skills.
• Must be a U.S. citizen or national, U.S. permanent resident, or lawfully admitted into the U.S.

Responsibilities

• Support hardware ownership of cryogenic propellant management components — contributing to requirements definition, conceptual/detailed design, and verification activities.
• Work on defined subsystems and components within the Zero-g Propellant Management IPT, escalating complex or ambiguous problems to senior engineers as needed.
• Support trade studies, component design/integration, first-order analysis, and supplier interface for fluid/gas hardware (valves, manifolds, regulators, pressure vessels, instrumentation).
• Track internal and external procurements and hardware dependencies to support subsystem delivery schedules.
• Participate in internal and external technical exchange meetings on cryogenic hardware development.
• Support DFM/DFA/DFT reviews for cryogenic hardware designs, flagging manufacturability concerns during design phases.
• Help translate engineering requirements into manufacturing processes for cryogenic fluid hardware (fabrication, cleaning, welding/brazing, assembly, leak/pressure testing).
• Develop and maintain manufacturing documentation: work instructions, process flow diagrams, tool designs, and inspection plans for assigned hardware.
• Support root cause analysis and corrective action for manufacturing non-conformances; contribute to MRB dispositions under guidance from senior engineers.
• Evaluate manufacturing methods relevant to cryogenic fluid systems (precision machining, additive manufacturing, cleaning/assembly techniques) and recommend improvements.
