Thermal System Analysis and Model Integrator Engineer III

Thermal System Analysis and Model Integrator Engineer III

Join to apply for the Thermal System Analysis and Model Integrator Engineer III role at Blue Origin
. 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 system that will return humans to the Moon, this time to stay. You will be a Thermal Analysis Engineer III within the Thermal Product Team, responsible for performing and leading thermal analysis projects at system‑level for our lunar landers during ground, launch, Earth orbit, cis‑lunar space, lunar orbit, and lunar surface mission phases.

• Own the delivery and quality of thermal analysis of the spacecraft system including when interfacing with other vehicles.
• Build thermal models in Thermal Desktop/Sinda based on system inputs from external teams.
• Integrate submodels from multiple contributing thermal analysts into a detailed system model.
• Maintain submodel build requirements documentation to ensure consistent modeling approach across submodels and seamless integration into the system model.
• Set up orbits/heating rates and case sets to cover analysis of all mission phases.
• Develop logic blocks to model components of the thermal control architecture.
• Predict spacecraft component temperatures and heater power across all mission phases.
• Perform model checks to ensure the accuracy and quality of results.
• Identify non‑compliances to thermal requirements and drive them to resolution.
• Perform trade studies and optimizations of thermal design solutions and collaborate with external teams on the trade offs.
• Document thermal analysis results and present at internal review boards and program gated reviews.
• Maintain and enforce model version control process to ensure proper review and consistent model use for generating thermal predictions.
• Maintain a simplified system model to perform analysis trade studies requiring quick turnaround times. Ensure consistency between detailed and simplified models.
• Perform model validation by correlating to test data.
• 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 using Thermal Desktop/Sinda.
• Established understanding of heat transfer fundamentals in space environment.
• Good understanding of common spacecraft thermal hardware.
