Senior Aerodynamics Engineer

Turning Space into a Transportation Layer for EarthWho 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:  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:  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  This position is on-site at Inversion HQ in Playa Vista, CA.  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  Experience with high-performance computing environments and large-scale CFD campaign automation  Experience with wind tunnel testing, including test planning, execution, and/or data reduction  Familiarity with 6-DOF flight simulation as a downstream consumer of aerodynamic databases  Prior experience working in startups and/or small independent teams  Our office headquarters is located in Playa Vista, CA. This position requires in-office presence.  The California annual base salary for this role is currently $137,000-$193,000.  Pay Grades are determined by role, level, location, and alignment with market data.  Individual pay will be determined on a case-by-case basis and may vary based on the following considerations: interviews and an assessment of several factors that are unique to each candidate, job-related skills, relevant education and experience, certifications, abilities of the candidate and internal equity. ITAR Compliance: To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
