Mechanical Engineer Senior - Marine Fluid System Design

About the role

This role is part of Blue Origin Operations, which includes Integrated Supply Chain, Test Operations, Safety, Quality, and Mission Assurance. It involves Manufacturing and Supply Chain support across all Blue Origin facilities.

Responsibilities

• Own the design, analysis, and engineering of cryogenic, pneumatic, and fluid systems for new vessel construction and fleet sustainment, including nitrogen generation and GN2 distribution systems.
• Develop and maintain piping and instrumentation diagrams (P&IDs), process flow diagrams (PFDs), and system schematics for marine fluid systems.
• Perform fluid system analyses including pipe sizing, pressure drop calculations, thermal analysis, flow modeling, and system transient simulations using relevant engineering tools.
• Define system architecture and develop technical specifications for cryogenic storage, vaporization, and distribution equipment suited for marine environments.
• Design and specify marine piping systems in accordance with ASME B31.1, ASME B31.3, ABS Rules, USCG CFRs, and other applicable marine standards.
• Specify fluid system components including valves, regulators, pumps, heat exchangers, pressure vessels, cryogenic storage dewars, vaporizers, and nitrogen generators for marine service.
• Create fabrication and installation drawings, assembly details, and bill of materials for piping and fluid system installations.
• Oversee shipyard fabrication and installation of piping and fluid systems, conducting in-process inspections and redline reviews for as-built documentation.
• Lead hydrostatic testing, pneumatic testing, leak testing, and system commissioning for marine fluid systems.
• Coordinate with the Senior Marine Electrical Engineer on electrical power requirements and motor control interfaces for fluid system equipment (pumps, compressors, vaporizers, etc.).
• Coordinate with the Marine I&C Engineer on instrumentation requirements, control logic, and automation interfaces for cryogenic and pneumatic systems.
• Coordinate with the Technical Lead (Analyst / Naval Architect) on fluid system classification compliance, weight and stability impacts, and vessel arrangement considerations.
• Coordinate with the Recovery Offshore Operations Engineer on recovery-specific fluid system interfaces and operational requirements for booster safing and inerting.
• Support the Project Construction Managers with technical guidance on piping installation sequences, fluid system fit-checks, and quality verification at the shipyard.
• Provide technical mentorship and direction to the Marine Fluids Engineer.
• Create preventive maintenance plans and procedures for cryogenic and fluid systems.
• Prepare technical documentation and present findings to stakeholders and senior management.
• Maintain configuration control of fluid system engineering documentation.

Requirements

• Minimum of a B.S. degree in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Marine Engineering, or equivalent.
• 10+ years of experience in fluids system design, analysis, and engineering with direct experience in cryogenic systems or high-pressure pneumatic systems.
• Experience understanding and developing fabrication and installation drawings for piping and fluid systems.
• Knowledge of standard components, installation, and fabrication methods of piping systems (pipe stock, fittings, connections, valves, fasteners, structural members, welding, etc.).
• Experience using analysis tools specific to piping and fluid systems (e.g., AFT Fathom/Arrow, CAEPipe, Bentley AutoPipe, CAESAR II, Sinda Fluint, Simulink, or equivalent).
• Knowledge of typical use, constraints, and specification of fluid components in tubing and piping systems (valves, regulators, pumps, heat exchangers, pressure vessels, etc.).
• Experience with design, operations, or maintenance of cryogenic systems.
• Strong safety mindset and experience, including hands-on experience planning and conducting hazardous operations involving cryogenic fluids or high-pressure systems.
• Demonstrated ability to lead technical work and mentor less experienced engineers.
• Demonstrated ability to collaborate with teams composed of multiple roles and disciplines to achieve a common goal.
• Ability to work at shipyard locations for extended periods and in physically demanding environments.
• Ability to travel (estimated 40–60% during construction phase).
