Propulsion Engineer

About the role

You will own the end-to-end design and analysis of propulsion hardware, translating conceptual requirements into detailed schematics and specifications that guide manufacturing and testing. You will lead the development of critical subsystems, ensuring that each component meets stringent performance, reliability, and safety standards for aerospace applications. You will collaborate closely with cross-functional teams to integrate your designs into larger systems, solving complex problems that arise during prototyping and qualification. You will be responsible for creating and maintaining technical documentation that captures design decisions, trade studies, and test results for future reference and regulatory compliance. You will apply advanced engineering principles to optimize propulsion system efficiency, durability, and manufacturability throughout the product lifecycle. You will support the definition of test objectives and success criteria, ensuring that validation activities directly address mission-critical requirements. You will contribute to the development of robust fault-tolerant architectures that enhance system resilience in demanding operational environments. You will represent the propulsion discipline in internal reviews and external engagements, communicating technical rationale to both engineering and executive stakeholders.
