Engineer - Fluid Systems Sr Verified today

Senior Fluids Engineer, Lunar Permanence

Blue Origin's Lunar Permanence business unit develops Blue Moon landers and related products. We are seeking a Senior Fluids Engineer with expertise in fluid dynamics to develop advanced fluid management technologies for waste management applications in space.

This role focuses on research, design, analysis, and validation of two-phase fluid separation systems. You will advance understanding of complex liquid-gas flow behavior across multiple flow regimes in microgravity and develop innovative fluid system solutions for space vehicles.

Responsibilities

• Develop, model, and validate fluid systems using analytical methods and simulation tools.
• Design, execute, and analyze experiments to characterize system performance and validate design assumptions.
• Collaborate with multidisciplinary engineering teams to integrate fluid systems into aerospace and spaceflight vehicles.
• Prepare technical documentation, engineering reports, and design presentations for internal and external stakeholders.
• Ensure fluid system designs comply with applicable safety, quality, and regulatory requirements.
• Participate in technical and design reviews, providing engineering recommendations to drive continuous product improvement.

Minimum Qualifications

• 10 years aerospace or fluids engineering experience (or similar discipline).
• Knowledge of liquid-gas two-phase flow, including flow regimes, pressure drop, and phase separation.
• Experience with microfluidics, capillary-driven flow, and fluid behavior in microgravity environments.
• Experience with air-liquid separators and two-phase flow systems, including design, analysis, testing, and performance evaluation.
• Experience with Computational Fluid Dynamics (CFD) for airflow, thermal, and fluid flow simulations to validate and optimize engineering designs.
• Must be a U.S. citizen or national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum.

Preferred Qualifications

• Masters or PhD in Physics specializing in fluid dynamics.
• Knowledge of fluid components typical in tubing and piping systems (valves, regulators, pumps, etc.).
• Knowledge of standard components, installation, and fabrication methods of piping systems (pipe stock, fittings, connections, valves, fasteners, welding, etc.).
• Experience with electrical control systems and architectures used for fluid system valve actuation, including command, power, instrumentation, and feedback interfaces.

Base Pay Range

CO: $133,500-$186,898.95
WA: $145,188-$203,263.20
Other site ranges may differ.

Additional Information

• Relocation provided.
• Travel expected up to 30% of the time.
• Interviews will include a technical assessment.
• Background check required for all positions.
• Benefits include medical, dental, vision, life insurance, paid parental leave, short and long-term disability, 401(k) match up to 5%, Education Support Program, stock options, and up to four weeks paid time off plus 14 company-paid holidays annually.
