Liquid System Engineer III — Cryogenic DFM

Position: Liquid System Responsible Engineer III — Cryogenic DFM
Application close date:

Applications will be accepted on an ongoing basis until the requisition is closed.

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 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.

This role is part of the Lunar Permanence business unit's Zero-g Propellant Management team, which develops cryogenic propellant management hardware for Blue Origin's Blue Moon lander product lines.

We're looking for a Liquid Systems Responsible Engineer with cryogenic fluids experience and a manufacturing-oriented mindset. You'll support hardware ownership on cryogenic propellant management components while also contributing directly to how that hardware is fabricated, assembled, and qualified for production. This role splits time between technical hardware support (requirements, design reviews, supplier coordination, verification) and manufacturing engineering (DFM/DFA input, process documentation, shop floor troubleshooting, non-conformance support) — working under senior engineer/lead guidance on more complex or ambiguous problems, with growing independence on well-defined scope.

Special Mentions Relocation provided

Travel expected up to 25% of the time Responsibilities include but are not limited to:

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.

Participate in process FMEAs, risk assessments, and validation activities for new production tooling/lines as hardware scales.

Ensure manufacturing processes align with AS9100/ISO 9001 quality and safety standards.

Collaborate with Manufacturing Engineering, Quality, and Supply Chain to identify efficiency and cost reduction opportunities.
