• Experience with Cryogenic Fluid Management techniques and technologies.
• Proficiency with Creo Parametric for parts, assemblies, weldments, and drawings.
• Working knowledge of GD&T per ASME Y14.5.
• Experience with configuration management and release processes.
• Knowledge of manufacturing materials, processes, and tolerance/stack-up analysis.
• Ability to work in a fast-paced environment.
• Excellent verbal, written, and graphical communication skills.
• U.S. citizenship or permanent residence or qualified refugee/asylee.

Responsibilities

• Work on complex cryogenic subsystems and components with the Zero-g Propellant Management Product Team.
• Support hardware ownership from definition through delivery, including design, verification, and integration.
• Track procurements and hardware dependencies.
• Support trade studies, component design and integration, and test support.
• Develop, modify, and release Creo models, assemblies, and drawings for cryogenic hardware.
• Generate fabrication drawings using Blue Origin standards and GD&T.
• Apply Model Based Definition and PMI on controlled models.
• Follow CAD conventions and Windchill CM requirements.
• Create Interface Control Models and Drawings.
• Deliver geometry to analysis teams for FEA.
• Support drawing release, manufacturing plans, and vehicle integration.
• Perform model and drawing checks and participate in design reviews.
• Support vendor RFQs, fabrication, inspection, and proof-test packages with BOMs.
