The Role Mach Industries is searching for a Rotordynamics Engineer to analyze the rotating and stationary components in the engine and guide solutions. The components under investigation include compressor and turbine rotors, stationary vanes, shafts, pressurized casings, and more. The analyst will own the components under investigation and be responsible for guidance on structural capability and improvement. They will work daily with aerodynamic and mechanical designers to develop these critical components at a rapid pace. Their components will be manufactured and tested in weeks rather than years. They will have a hand with the design, manufacturing and testing. We are on a mission to deliver high-performance small turbine engines at scale needed by rethinking the fundamentals to enable high-rate, scalable manufacturing. This is an opportunity to shape the future of propulsion from the ground up, and it takes the best people to make that happen. We are looking for those who thrive in diverse, fast-paced, high-expectation environments and are driven to build what’s never been built before. Key Responsibilities Own the rotordynamics analysis at both the component and system level (modal analysis, campbell plot development, determination of critical speed
