Liquid System Responsible Engineer II — Cryogenic Fluids CAD & Design

Blue Origin•Huntsville, WA

About The Position

The Liquid System Responsible Engineer II is part of Blue Origin’s Lunar Permanence business unit, which develops Blue Moon landers and related products. The role supports cryogenic propellant management hardware, with a focus on CAD design and drafting as well as technical requirement development. Work ranges from concept-level design through release-ready Creo models and drawings and spans system definition, interfaces, conceptual and detailed design, component development, assembly, verification, and operation. The engineer works with internal and external suppliers and contributes to safe human spaceflight. The position is part of the Zero-g Propellant Management Product Team (IPT). It supports hardware ownership from definition through delivery, including design, verification, integration, procurements, and delivery schedules. The engineer develops and releases Creo models, assemblies, and drawings for cryogenic hardware such as valves, manifolds, tubing, pressure vessels, and support structures. Deliverables may include interface control models and drawings, fabrication and assembly drawings, BOMs, weldment and machined-part details, inspection drawings, and as-built redlines. The role follows Blue Origin CAD conventions, drafting standards, configuration-management requirements, and controlled release processes, and supports analysis, manufacturing, vendor activities, and vehicle integration. Relocation is provided. Travel is expected up to 25% of the time. Base pay ranges by location: California $99,201.00–$138,880.35; Colorado $90,934.00–$127,307.25; Washington $99,201.00–$138,880.35. Other site ranges may differ.

Experience with Cryogenic Fluid Management techniques and technologies.
Demonstrated proficiency with Creo Parametric for parts, assemblies, weldments, and drawings.
Working knowledge of GD&T per ASME Y14.5 and ability to apply it to fabricated, machined, and welded fluid-system hardware.
Experience working within a formal configuration management, engineering change, or release process such as CN, ECO, or ECN.
Knowledge of common manufacturing materials, processes, and tolerance/stack-up analysis sufficient to produce manufacturable drawings.
Ability to work effectively and collaboratively in a fast-paced, dynamic work environment.
Excellent verbal, written, and graphical communication skills.
Applicants must be U.S. citizens or nationals, U.S. permanent residents, or lawfully admitted into the U.S. as refugees or granted asylum.
Ability to meet Blue Origin’s standard background-check requirement.

Nice To Haves

M.S. in Aerospace Engineering, Mechanical Engineering, Physics, or a related technical subject area.
Human-rated space vehicle experience.
Finite Element Analysis experience; ANSYS preferred.
Experience with upper stages and spacecraft.
Experience with the entire life cycle of a propulsion and fluid system.
Experience with Windchill PDM in a production environment, including workflow, revisioning, and BOM management.
Experience with Model Based Definition and PMI authoring, including familiarity with trade-offs between fully defined MBD models and reduced-content drawings.
Experience drafting structural weldments to AWS D1.1 / D17.1, including weld symbol literacy and weld-prep detailing.
Background in DFM/DFA principles as applied to CAD design choices.
Prior aerospace, defense, or other high-reliability industry experience.

Responsibilities

Work on complex cryogenic subsystems and components as part of the Zero-g Propellant Management Product Team, escalating ambiguous or high-risk problems to senior engineers as needed.
Support hardware ownership from definition through delivery, contributing to design, verification, and integration activities for assigned components.
Track internal and external procurements and hardware dependencies to support subsystem delivery schedules.
Contribute to fluids propulsion design engineering tasks, including trade studies, component design and integration, first-order analysis, test support, and supplier interfaces as opportunities arise.
Participate in internal and external cryogenic technology development meetings.
Develop, modify, and release Creo Parametric engineering models, assemblies, and drawings for cryogenic propellant management hardware, including valves, manifolds, tubing, pressure vessels, and support structures.
Generate fabrication and assembly drawings in accordance with Blue Origin drafting standards and applicable GD&T requirements.
Apply Model Based Definition practices where applicable, embedding PMI such as datums, notes, and finish callouts on models when MBD is the controlled deliverable.
Follow Blue Origin CAD modeling conventions and Windchill configuration-management requirements; maintain product data and support changes through the CN-controlled release process.
Create Interface Control Models and Interface Control Drawings for cryogenic fluid system hardware.
Deliver geometry to analysis teams to support Finite Element Models.
Support hardware drawing release, manufacturing plan development, and integration onto the vehicle.
Perform model and drawing checks and participate in design reviews to ensure conformance with engineering, safety, and program standards before release.
Support vendor RFQs, fabrication, inspection, and proof-test packages by producing associated deliverables, including BOMs, weldment details, machined-part details, inspection drawings, and as-built redlines.
