Job description

ABOUT FIREFLY AEROSPACE
Firefly Aerospace is a space and defense technology company on a mission to reliably and repeatedly launch, land, and operate space systems from Earth to the Moon and beyond. As the partner of choice for critical space missions, Firefly is the first commercial company to launch a satellite to orbit with 24-hour notice and the first company to achieve a successful Moon landing. Headquartered in north Austin, Texas, Firefly is looking for passionate, hardworking innovators to join our team and help fuel our successful trajectory into space.
SUMMARY
We are seeking a Structural Dynamics Engineer to serve as the domain expert in high-frequency dynamics for launch vehicles and spacecraft. This role focuses on the advanced analysis, modeling, derivation, and verification of complex dynamic environments-including random vibration, shock, acoustics and engine dynamics-through flight data processing, empirical and physics-based methods, and high-fidelity numerical simulation.
The engineer will act as a technical authority, providing leadership and guidance to design, propulsion, test, and structures teams to ensure structural integrity, mitigate dynamic risks, and enable mission success under the extreme conditions of launch and flight.
RESPONSIBILITIES
Dynamic Environment

  • Derive levels using flight data as well as duration using SMC-S-016 method and damage based analysis
  • Derive lift off random vibration level using NASA-SP8072
  • Derive ascent random vibration level using barret method, spann method or other empirical method to support early design cycles
  • Applies advanced signal-processing techniques for root-cause analysis and anomaly resolution
  • shock
  • Derive levels using flight data
  • Derive levels using source shock amplitude and transmissibility as well as attenuation
  • Serves as recognized authority on shock attenuation and transmissibility mechanisms
  • Utilizes vibro-acoustic software to investigate and resolve shock-related phenomena

Engine dynamics
  • Leads rotor-dynamics analyses to evaluate pump bearing and impeller blade performance
  • Provides technical direction for engine test-stand instrumentation (accelerometers, microphones, pressure transducers, and specialized sensors)
  • Processes and interprets engine test data (acceleration, acoustic, and pressure) to support anomaly resolution and design improvements
  • Applies flow-induced vibration (FIV) principles to pressurized line-set and component design
  • Analyzes acoustic cavities and their coupling effects on engine vibration response

Advanced Structural Dynamics Methods
  • Applies frequency-based substructuring (FBS) techniques to integrate test and analysis models
  • Develops Craig-Bampton reduced-order models in Nastran for spacecraft delivery to launch-vehicle providers in support of coupled-loads analysis (CLA)
