Chemical Process Engineer

About the role

This position supports the Starship launch team by designing and building fluid systems for launch, landing, and test sites. You will focus on the creation and processing of cryogenic propellants to support the operation of the most powerful rocket in existence. In this role, you are responsible for the end-to-end execution of complex fluid systems that directly enable vehicle testing and mission success. You will translate high-level engineering requirements into detailed designs for cryogenic production and distribution infrastructure. Your work will ensure that propellant supply chains are reliable, safe, and scalable for rapid iteration. You will act as a technical leader in the development of methane and oxygen systems critical to Starship operations. This position requires a hands-on engineer who thrives in a fast-paced, iterative development environment.
