Senior Dynamics Engineer - Spaceflight Loads & Dynamics

Triwill Group; California (MO); On-site; USD 137,000 - 193,000; Full time

Job summary

Inversion is seeking a Senior Dynamics Engineer to own loads, structural dynamics, and multibody dynamics analyses for a next‑gen reentry vehicle. You will collaborate across vehicle architecture, structures, mechanisms, and test to define dynamic environments and validate designs through analysis and hardware correlation.

Reporting to the Director of Mechanical, you will shape the dynamic behavior from concept to production, drive design decisions, and present progress in design reviews while

Qualifications

• Bachelor's degree in aerospace or mechanical engineering or equivalent.
• 5+ years in loads, structural or multibody dynamics for aerospace/defense.
• Strong fundamentals in rigid-body and structural dynamics.
• Experience with multibody dynamics models for mechanisms or deployment systems.
• Experience defining mechanical loads and dynamic environments for flight hardware.
• Familiarity with FEA tools (ANSYS, Abaqus, NASTRAN, FEMAP).
• Experience with MD tools (ANSYS Motion, Adams, Simpack).
• Excellent verbal and written communication; cross-functional collaboration.

Responsibilities

• Own development of vehicle loads, structural dynamics, and multibody dynamics analyses from early architecture through hardware realization.
• Define and mature load cases and dynamic environments, including launch, shock, vibration, separation, deployment, and other transient mechanical events.
• Develop and maintain multibody dynamics models to evaluate separation events and other critical mechanism-driven vehicle behaviors.
• Partner closely with structures and mechanisms engineers to translate dynamic analysis results into design requirements, sizing inputs, interface loads, and architecture decisions.
• Support development of structural dynamics models, including modal characterization, transient response, and dynamic load prediction for flight hardware.
• Drive dynamic trade studies to evaluate mechanism architecture, deployment performance, structural response, and system sensitivity under uncertain and evolving design conditions.
• Help define test objectives, instrumentation needs, and correlation plans for mechanism, structural, and dynamic development tests.
• Correlate simulation results to test data and refine models, assumptions, and design recommendations based on hardware learnings.
• Present analysis progress, technical risks, and recommended paths forward in design reviews and cross-functional program forums.
• Operate effectively in a fast-paced, ambiguous development environment, balancing model fidelity, engineering judgment, and schedule needs.
