Liquid System Responsible Engineer II — Cryogenic Fluids CAD & Design Verified today

About the role

This role is part of the Lunar Permanence business unit, which develops Blue Origin's Blue Moon landers and related products. You will support the model-and-drawing side of cryogenic propellant management hardware, from concept-level design through release-ready Creo models and drawings.

What you will do

• 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.
• Develop, modify, and release engineering models, assemblies, and drawings in Creo Parametric for cryogenic propellant management hardware, including valves, manifolds, tubing, pressure vessels, and support structure.
• Generate fabrication and assembly drawings in accordance with Blue Origin drafting standards and applicable GD&T requirements.
• Apply Model Based Definition (MBD) practices where applicable, embedding PMI (datums, notes, finish callouts) on the model for programs and hardware where 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 checks, drawing checks, and participate in design reviews to ensure conformance with applicable engineering, safety, and program standards before release.
• Support vendor RFQs, fabrication, inspection, and proof-test packages by producing associated deliverables (BOMs, weldment details, machined-part details, inspection drawings, as-built redlines).
• Participate in internal and external cryogenic technology development meetings.

Minimum qualifications

• B.S. in Aerospace Engineering, Mechanical Engineering, Physics, or related technical subject area.
• 2+ years of experience in cryogenic fluids and mechanical systems/components.
• Experience supporting the development, integration, or certification of aerospace systems for flight.
• Experience with fluid/gas components (i.e., solenoid valves, directional valves, manifolds, regulators, pressure vessels, and instrumentation).
• 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 the ability to apply it to fabricated, machined, and welded fluid system hardware.
• Experience working within a formal configuration management / engineering change / release process (CN, ECO, ECN, or equivalent).
• Solid grasp of common manufacturing materials, processes, and tolerance/stack-up analysis sufficient to produce manufacturable drawings without back-and-forth.
• Ability to work effectively and collaboratively in a fast-paced, dynamic work environment.
• Excellent verbal, written, and graphical communication skills.

Preferred qualifications

• M.S. in Aerospace Engineering, Mechanical Engineering, Physics, or related technical subject area.
• Human-rated space vehicle experience.
• Finite Element Analysis (FEA) 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 (MBD) and PMI authoring, including familiarity with the 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 they apply to CAD design choices.
• Prior aerospace, defense, or other high-reliability industry experience.

Compensation and work terms

• Base pay range for CA: $99,201.00 to $138,880.35
• Base pay range for CO: $90,934.00 to $127,307.25
• Base pay range for WA: $99,201.00 to $138,880.35
• Other site ranges may differ.
• Relocation provided.
• Travel expected up to 25% of the time.
• Benefits include medical, dental, vision, basic and supplemental life insurance, paid parental leave, short and long-term disability, 401(k) with a company match of up to 5%, and an Education Support Program.
• Stock options for all regular employees working at least 20 hours/week.
• Paid time off: up to four weeks per year based on weekly scheduled hours, and up to 14 company-paid holidays.
