Overview
Application close date:
Applications will be accepted on an ongoing basis until the requisition is closed.
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 is part of the Lunar Permanence business unit, which develops Blue Origin's Blue Moon landers and related products. To further Blue Origin's mission of millions of people living and working in space for the benefit of Earth, we are building sustainable infrastructure for our transport of crew and cargo from Earth to the lunar surface.
As part of a hardworking team of engineers, you will contribute to the definition and development of spacecraft thermal control systems. You should be comfortable working in a fast-paced and often uncertain environment, contributing to innovative solutions, while demonstrating personal leadership, technical competence, and attention to detail.
You will work directly with NASA as part of the Human Landing System (HLS) Sustaining Lunar Development (SLD) program. You will play a key role in developing the Lunar Transportation system that will return humans to the Moon, this time to stay.
Thermal Analysis Engineer III within the Thermal Product Team. You will be responsible for performing and leading thermal analysis projects at system-level and/or subsystem-level for our lunar landers during ground, launch, Earth orbit, cis-lunar space, lunar orbit, and lunar surface mission phases.
Contribute to a team of Thermal Engineers simultaneously developing groundbreaking lunar landers. 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:
- Engineers may focus on system-level analysis of the lunar lander or component-level analysis of products, depending on their background and interest.
- Own the delivery and quality of thermal analysis of one or more spacecraft systems/components, often including the work of several contributing analysts
- Build thermal models in Thermal Desktop based on system inputs from external teams
- Collect analysis inputs from stakeholders and responsible engineers
- Check own work and correct errors independently
- Post process analysis results to draw engineering conclusions from output data
- Predict spacecraft and part temperatures across all mission phases
- Identify non-compliances to thermal requirements and drive them to resolution
- Perform trade studies and optimizations of thermal design solutions and collaborate with external subsystems on the trade offs
- Author and publish analysis reports in various mediums to support engineering decision making
- Generate and present design review content to subsystem, vehicle and business unit partners and customers, including program gated reviews
- Create work plans, document progress and report status to leads and managers
- Lead and mentor early-career analysis engineers
- Minimum of a B.S. degree in mechanical or aerospace engineering
- 5 years of relevant Thermal Analysis experience
- Established understanding of heat transfer fundamentals in space environment
- Good understanding of common spacecraft thermal hardware
- Understanding of aerospace hardware verification and validation process
- M.S. or PhD degree in mechanical or aerospace engineering
- 8 years of relevant Thermal Analysis experience
- Strong understanding of pumped fluid loop hardware such as pumps, cold plates, radiators, valves, heat exchangers, etc. and semi-passive devices like sensors and heaters
- Familiar with thermal environments of lunar missions
- Experience solving a variety of thermal problems demonstrating breadth in application
- Demonstrated experience in model correlation based on test results
- Expert in Thermal Desktop and Sinda/Fluint, including model validation and test correlation
- Proficiency in one or more programming languages (e.g., Python, C/C++, FORTRAN, Matlab)
