Job description

Sierra Space Careers:
At Sierra Space, we build the missions and systems that keep our world secure in the domain above Earth.
Sierra Space team members share a spirit of innovation and collaboration and a belief that we can deliver on the boldest missions in space today. Together with our customers, we aim to safeguard our nation, sustain human presence in space, and secure the freedom of operations in low Earth orbit and beyond.
Our success is measured by the trust of those who rely on what we build and deliver, and our technologies keep the United States and its allies mission-ready throughout space.
We are mission-driven, and together, we are an extraordinary team.
About the Role
The Propulsion Engineer III will play a critical role in the design, development, and testing of advanced propulsion systems for aerospace applications. This position requires a deep understanding of propulsion engineering principles, including fluid dynamics, thermodynamics, and combustion processes. The successful candidate will be responsible for leading complex projects, conducting detailed analyses, and ensuring the reliability and performance of propulsion systems. This role involves close collaboration with multidisciplinary teams, including mechanical, electrical, and systems engineers, to deliver innovative solutions that meet stringent performance and safety requirements.
