Propulsions Engineer

About JT4, LLC

JT4 provides engineering and technical support to multiple western test ranges for the U.S. Air Force, Space Force, and Navy under the Joint Range Technical Services Contract (J-Tech II). The company develops and maintains realistic, integrated test and training environments, preparing the nation's war-fighting aircraft, weapons systems, and aircrews for today's missions and tomorrow's global challenges.

About the Role

JT4 is seeking Aircraft Propulsion Integration (PI) Test and Evaluation (T&E) engineers to join our team. This role is critical for ensuring the safety and effectiveness of propulsion systems across single-engine and multi-engine aircraft platforms. You will serve as a technical authority, bridging the gap between ground testing and flight operations.

In this position, you will review and provide input for PI documents supporting Technical Review Boards (TRB), Safety Review Boards (SRB), and Report Integrated Product Teams (RIPT). A key part of your day involves providing enterprise-level coordination for all projects and supporting the Director of Propulsion Safety and Technical Review (DoPSTR) during Joint Propulsion Council meetings. You will collaborate with allied engineering disciplines—including avionics, armament, electronic warfare, and structures—to coordinate technical input for PI T&E efforts.

Your technical contributions will drive test planning, the development of data analysis tools, and the definition of engine test instrumentation requirements. You will actively support test execution, including control room operations, and perform post-flight data analysis to assist with technical reporting. This role offers the opportunity to work on high-stakes projects that directly impact national defense capabilities.
