Senior Dynamics Engineer

Turning Space into a Transportation Layer for Earth

Who We Are:

Inversion builds advanced reentry systems to deliver next-generation capabilities from space.
 
Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach.
 
Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds.
 
Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics.

What You'll Do

As a 

Senior Dynamics Engineer

 at Inversion, you will own the development of loads, structural dynamics, and multibody dynamics analyses for one of the most capable reentry vehicles ever developed. 

You’ll

 work across vehicle architecture, structures, mechanisms, and test to define critical dynamic environments, mature structural and deployment system designs, and 

validate

 key aspects of vehicle performance through analysis and hardware correlation.

This is a unique opportunity to shape the dynamic behavior of a new aerospace vehicle from early concept through qualification and production. You will be a key member of the 

Mechanical

 team, reporting to the 

Director of Mechanical

.

Key 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

Required Qualifications

• Bachelor’s degree in Aerospace Engineering

  , Mechanical Engineering, Engineering Mechanics, a related field, or equivalent technical experience

• Typically 

  5+ years of professional experience

   in loads, structural dynamics, multibody dynamics, or related analysis for aerospace, defense, or similarly demanding applications

• Strong fundamentals in

   rigid-body dynamics, structural dynamics, vibration, transient response, and mechanical system behavior

• Experience developing and applying 

  multibody dynamics models

   for mechanisms, deployment systems, separation events, or other complex dynamic hardware

• Experience defining and evaluating 

  mechanical loads and dynamic environments

   for flight hardware or other high-consequence systems

• Familiarity with finite element analysis tools such as 

  ANSYS, Abaqus, NASTRAN, FEMAP, or equivalent

  , with emphasis on 

  modal, transient, and dynamic structural analysis

• Experience with multibody dynamics tools such as 

  ANSYS Motion, Adams, RecurDyn, Simpack, MATLAB/Simulink, or similar

• Demonstrated ability to work cross-functionally with design, structures, manufacturing, and test teams to turn analysis into sound hardware decisions

• Demonstrated excellent verbal and written communication skills

• Proven ability to work effectively in a fast-paced environment

Desired Qualifications

• Master’s degree in Aerospace Engineering

  , Mechanical Engineering, Engineering Mechanics, a related field, or equivalent experience

• Experience owning both

   loads / structural dynamics and multibody dynamics analysis

   for a vehicle or mechanism development program

• Experience with 

  deployment mechanisms, separation systems, release events, or payload delivery systems

• Experience generating 

  design loads and dynamic requirements

   used to size structures, mechanisms, and interfaces

• Experience supporting 

  test planning, instrumentation definition, model correlation, and post-test analysis

• Experience in the design, analysis, or test of 

  qualified flight hardware

• Experience working on first-of-kind or highly integrated aerospace systems in an 

  ambiguous, fast-moving development environment

• Experience scripting or automating analysis workflows using 

  Python, MATLAB, or similar tools
