Astro Mechanica is looking for a Senior Rotordynamics Engineer with the knowledge and skill to refine the development of our terrestrial and aviation turbomachinery through your understanding of the detailed physical processes that happen within them. Your experience may be rooted in ground-power, aviation, or space-based applications. You understand the physical behavior of rotating systems as deeply on paper as you do at the test stand, and you’ve built the analytical models to prove it. ## WHAT YOU’LL DO:
Lead rotordynamic analysis of turbomachinery systems, including critical speed prediction, stability margins, imbalance response, torsional analysis, modal analysis, and Campbell diagram development
Bearing selection, preload definition, stiffness and damping trade studies, thermal management and lubrication system
Define and execute test campaigns instrumented specifically for rotordynamic validation
Develop and iterate computational models (StarCCM+, AxSTREAM) with rotordynamic constraints in mind
Utilize propulsion cycle models (GasTurb, NPSS) to assess how compressor maps and mechanical behavior interact under dynamic loading conditions
Define GD&T for rotating assemblies through tolerance analysis, considering the effects on rotor balance, seal clearances, and dynamic behavior
Partner with manufacturing to ensure production of high-precision rotating components with balance grades, runout tolerances, and assembly sequence in mind
WHAT WE’RE LOOKING FOR:
5+ years in turbomachinery design with demonstrated rotordynamic analysis and mechanical packaging ownership on real hardware
Hands-on experience with rotordynamic modelling tools (DyRoBes or equivalent)
Experience with blade and compressor geometry development using CFD, streamline curvature, and 1D meanline methods (StarCCM+, AxStream)
Experience with test instrumentation and data reduction specifically for mechanical validation (vibration, whirl, and rotor response)
Experience with propulsion cycle tools (GasTurb, NPSS) and how compressor mechanical behavior couples to cycle performance
Proficient in CAD for rotating assemblies (Siemens NX) and multiphysics analysis
Experience with scripting for analysis automation and post-processing (Python, MATLAB)
Effective communicator capable of leading cross-functional design reviews and contributing to system architecture discussions
PERKS & BENEFITS:
Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)
401(k) program and transparent stock option plan
Self-managed and flexible time-off policy, including PTO, paid holidays, and sick time
Flexible work environment
ADDITIONAL INFORMATION:
At Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture. We consider working in the office five days a week an essential part of the employee's role. We proudly recruit and hire a diverse workforce and are committed to creating an inclusive environment for all employees.
