CFD Analyst

Akron, Ohio /
Engineering /
We are an aerospace R&D company building experimental and certified airships. We are developing advanced technologies to dramatically increase the capabilities and lower the cost of 21st-century airships.
LTA’s airships will have the ability to complement and even accelerate humanitarian disaster response and relief efforts, especially in remote areas that cannot be easily accessed by plane and boat due to limited or destroyed infrastructure. We ultimately aim to create a family of aircraft with zero emissions that, when used for shipping goods and moving people, would substantially reduce the global carbon footprint of aviation.

We are seeking a motivated CFD Analyst to conduct CFD analysis on a wide range of facets related to revolutionary ‘lighter than air’ flight vehicles in Akron, OH. You will work closely with a dynamic engineering and design team, helping to provide subject matter expertise on CFD-related topics. We believe in fast-cycle development with the motto “build a little, test a little, learn a lot.”

We are seeking a mission-driven, passionate CFD Analyst to perform CFD analysis on every facet of our flight vehicle.
