Advanced Reentry Technologies

Who We Are:

Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.

The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.

Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.

Position Overview

Inversion's reentry vehicles fly from orbital velocity to a precision landing, and every design decision, simulation, etc. along the way rests on an accurate characterization of how the vehicle flies. As a Senior Aerodynamics Engineer, you will generate and database the aerodynamic characteristics of our vehicles across the full flight envelope, aggregating data from high-fidelity CFD, lower-order methods, and wind tunnel testing into database products that drive system-level simulations. In this role, you will:

Key Responsibilities:

Develop and maintain aerodynamic force and moment databases spanning the full flight envelope, from hypersonic entry through terminal flight
Predict the aerodynamic forces and moments acting on Inversion reentry vehicles using high fidelity CFD tools across their flight envelopes.
Apply lower-order tools panel codes, Newtonian aerodynamics, and handbook methods to efficiently populate the broader envelope
Aggregate data of varying fidelity into coherent database products and define associated uncertainties to drive 3-DOF and 6-DOF system-level simulations
Support downstream users across GNC, simulation, and mission design in applying the databases correctly
Build and mature the tooling and automation behind database generation and delivery
Refine models using wind tunnel and flight-testing data

Required Qualifications:

Bachelor's degree in Aerospace or Mechanical Engineering, or equivalent experience
Typically, 5+ years of experience in aerodynamic analysis of aerospace vehicles (reentry, hypersonic, missile, launch, or high-performance aircraft systems)
Experience with high-fidelity CFD analysis of compressible external flows (e.g., FUN3D, OVERFLOW, CART3D, US3D, Kestrel, or similar)
Experience with lower-order aerodynamic prediction methods, such as panel codes and Newtonian/modified Newtonian aerodynamics
Experience with handbook methods and empirical aerodynamic correlations
Experience aggregating aerodynamic data from sources of varying fidelity into an overall database product used to drive vehicle simulation and design
Strong fundamentals in compressible aerodynamics across speed regimes and in vehicle static and dynamic stability
Proficiency in programming languages like Python, MATLAB, C++, or Fortran for analysis tooling and automation
Proven ability to work effectively in a fast-paced environment, including prototyping and rapid iteration of new products
Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.

Desired Qualifications:

Master's or PhD in Aerospace or Mechanical Engineering, or an equivalent field
Experience with the aerodynamics of reentry, hypersonic, or lifting-body vehicles
Experience with uncertainty quantification and the definition of aerodynamic dispersions for Monte Carlo simulation
Experience reconciling aerodynamic models against flight test data, including aerodynamic parameter identification
Familiarity with Fidelity Pointwise, Link3D, or equivalent meshing software for generating high-quality meshes
