Senior Thermal Engineer

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 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 thermal and fluid system design across New Glenn spaceflight systems. You will share in the team's impact on these systems across their full lifecycle, from early concept and configuration through flight operations and sustaining engineering.

This role is analysis-intensive: you will integrate customer-provided payload thermal models and generate thermal predictions for payloads and the payload compartment during launch and ascent, while supporting analysis across all phases of flight. This work includes applying aerothermal, radiative, and natural environments to integrated vehicle thermal models. As the focal point for thermal analysis requests from customers and multiple internal teams, you will define analysis scope, assumptions, and deliverables, and deliver integrated thermal analyses that drive design, verification, and mission decisions.

You will build, maintain, and configuration-manage integrated thermal models, inputs, and results, and document your analyses in formal reports and data books. You will also review and critique models and results produced by other engineers and mentor junior team members.

We are looking for someone who will apply technical expertise, leadership and a commitment to quality to positively impact safe human spaceflight. Passion for our mission and vision is required!
