Company Details

Building humanity’s multiplanetary future.

Relativity is the first and only company to automate aerospace manufacturing by integrating intelligent robotics, software, and proprietary metal 3D printing technology. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days. Our long-term goal is to upgrade humanity’s industrial base on Earth and on Mars.  


The combustion devices teams designs, analyzes and tests the combustion devices & heat exchangers of the Aeon engine.  We collaborate closely with our manufacturing team and our Stennis test team to deliver high-performing components to the engine system.  We strive for continuous improvement and support the development of our technical hardware and human teammates alike.

What you’ll do: 

You will own the development of our engine heat exchangers from concept through manufacturing and implementation.  This role involves a range of skillsets: design, analysis (structural, thermal, fluid), manufacturing, test, project management, and communication. You will work across teams and departments and take ownership of projects of your creation. In order to be successful in this role, you should be someone who thrives in ambiguity and be capable of leading collaborative projects to completion with minimal oversight.
