Mechanical Engineer - Fluid System Design (All Levels) Verified today

About the role

As a Mechanical Engineer in Fluid System Design at Blue Origin Operations, you will develop systems to test rocket engines, components, and integrated space flight vehicles. Working with a team of mechanical and fluid engineers, you'll contribute to all aspects of test stand design, from designing fluid and structural systems for test facilities to supporting supplier coordination and bringing new test systems from concept through commissioning.

What you will do

• Support design and development of fluid and mechanical systems for ground test facilities across the system lifecycle, from System Requirement Review (SRR) through Pre-Activation Review (PAR)
• Develop and release engineering deliverables including P&IDs, models, drawings, eBOMs, and engineering analyses under the guidance of senior engineers
• Apply fluid mechanics, structural analysis, and system integration fundamentals to the design of high-pressure gas, cryogenic, and propellant fluid systems, including process architecture, layout, and component selection
• Design and develop mechanical test fixtures and structural supports
• Support hazard assessments including Process Hazard Analysis (PHA) and Hazard and Operability Studies (HAZOPs)
• Participate in design reviews (IDR, FDR) and build reviews; support PAR readiness activities including system walkdowns
• Coordinate with suppliers on technical requirements under supervision; support tracking of cost and schedule inputs
• Support proof testing, passivation, and cleaning of fluid system components to required IEST cleanliness standards
• Apply industry standards including ASME B31.3 and ASME Boiler and Pressure Vessel Code (BPVC) to design work
• Provide on-site support during fabrication, installation, and start-up of new facilities or upgrades
• Identify and communicate technical, cost, and schedule risks to the team or project lead
• Maintain configuration management of engineering deliverables in Windchill

What you need

• Bachelor of Science in Mechanical, Manufacturing, Electrical, or Aerospace Engineering (other relevant fields may apply) from an accredited university
• Experience in a manufacturing, industrial, or process engineering role: 0-3 years for Level 1, 3+ years for Level 2, 5+ years for Level 3, 8+ years for Senior level
• Foundational knowledge of fluid mechanics, structural analysis, and system integration
• Demonstrated knowledge of fluid system components including valves, regulators, and pumps for cryogenic, propellant, and high-pressure gas applications
• Practical knowledge of standard installation and fabrication methods for piping systems, connections, fasteners, and welding
• Working knowledge of industry standards including ASME B31.3 and ASME Boiler and Pressure Vessel Code (BPVC)
• Ability to create and interpret engineering drawings and P&IDs
• Excellent written and verbal communication skills

Nice to have

• Advanced engineering degree
• Experience with PTC Creo/ProEngineer, ProPiping, or AutoCAD Plant/P&ID
• Experience with PLM configuration management tools such as Windchill
• Familiarity with pipe stress analysis tools such as Bentley AutoPipe, CAESAR II, or equivalent
• Familiarity with fluid system simulation tools such as AFT Arrow/Fathom or equivalent
• Experience with static or non-linear FEA analysis (e.g., ANSYS)
• Knowledge of aerospace fluid system cleanliness standards (IEST-STD-CC1246)
• Familiarity with propellant handling or propulsion system design and testing
• Exposure to Process Hazard Analysis (HAZOP, FMEA) or similar safety assessment methodologies
• Experience operating or commissioning test facilities
