Job description

About the role

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! This role supports the development and operations of New Glenn, a single-configuration, heavy-lift orbital launch vehicle capable of routinely carrying people and payloads to low-Earth orbit, geostationary transfer orbit, cislunar, and beyond. Its first stage is fully reusable, and the vehicle was designed from the beginning to be human-capable. As part of a small, passionate, and accomplished team of engineers and analysts, you will support all aspects of thermal and fluid system design for our next-gen stage two development effort. You will share in the team’s impact on the systems through their entire lifetime, from early conceptual design and configuration through flight operations and sustaining engineering. The responsibilities of this position will be analysis intensive, primarily supportive of development and verification of stage two component and vehicle thermal and fluid environments and performance requirements. You will implement aerothermal, rocket plume heating, and natural environments during all phases of flight. You will own the documentation and maintenance of analysis inputs, models, and results in reports and databooks. As the upper stage transitions from initial design, release, and qualification testing into the production and flight-test phase, you will support production issues, ongoing testing, and mission operations. We are looking for someone to apply their technical expertise, leadership skills, and commitment to quality to positively impact safe human spaceflight. Passion for our mission and vision is required!

Responsibilities

• Conduct thermal and fluids analysis to define performance and operations for upper-stage spaceflight systems, define hardware requirements, and resolve technical challenges
• Implement aerothermal, rocket plume heating, and natural environments across all phases of flight
• Generate and run thermal/fluids models to predict system performance across a wide range of environments
• Evaluate bounding thermal conditions against material and design capabilities
• Own the documentation and maintenance of analysis inputs, models, and results in reports and data books
• Support development and verification of component and vehicle thermal and fluid environments and performance requirements
• Support the systems through their full lifecycle, from conceptual design and configuration through flight operations and sustaining engineering

Minimum Qualifications

• Minimum of a B.S. degree in Mechanical or Aerospace Engineering
• 5+ years of experience in thermal or thermodynamic analysis
• Experience with one or more fluid or thermal modeling tools is required (e.g., ANSYS Workbench, ANSYS Classic, SINDA/FLUINT, Thermal Desktop, etc.)
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum

Desired Qualifications

• 10+ years of experience and an MS degree
• Demonstrated expertise with Thermal Desktop, SINDA/FLUINT, FloCAD
• Experience modeling launch vehicle systems
• Experience with cryogenic systems
• Knowledge of MATLAB
