About Radia

Radia is a dual use aerospace company developing Wind Runner™, the world’s largest cargo aircraft. Wind Runner is designed to enable direct transport of oversized cargo across defense, energy, commercial, aerospace, and humanitarian missions without reliance on specialized infrastructure. Radia is headquartered in Boulder, Colorado and Rome, Italy, with a growing global partner and supplier network.

• Design, loft and optimize components that affect the aircraft aerodynamics and outer mold line (OML).
• Build models, clean CAD geometry, and generate computational meshes to run CFD simulations that:
  • Inform aircraft trade studies and configuration design decisions using appropriately fidelity levels.
  • Support aerodynamic design across all phases, from concept development through certification.
• Develop and maintain high-fidelity aerodynamic databases for performance prediction, external-loads analysis, and real-time six-degree-of-freedom (6-DOF) simulations.
• Correlate and validate CFD results against simulations of varying fidelity (e.g. cross-code comparisons, wind-tunnel testing, and flight-test data). Iterate models as new data becomes available.
• Post-process and analyze simulation and test data. Summarize results in reports and presentations for internal and external stakeholders, as needed.
• Collaborate with cross-functional teams (performance, acoustics, loads, stability and control, control laws, systems, and instrumentation) to define simulation parameters and requirements, ensure model accuracy, and provide CFD expertise to guide design decisions.
• Develop and improve the software methods, tools, and workflows that support aerodynamic modeling.
• Support verification and validation activities that rely on model outputs (e.g., failure hazard assessments (FHAs)).
• Train and mentor junior aerodynamics engineers.

• B.S., M.S., or Ph.D. in aeronautical engineering or a related field
• 15+ years of experience with a B.S., 10+ years with an M.S., or 8+ years with a Ph.D. modeling subsonic, fixed-wing aerodynamics using CFD and validating results with wind-tunnel experiments
• Expert-level knowledge of subsonic, fixed-wing aerodynamics; strong theoretical background in fluid mechanics and CFD
• Experience with surface parameterization and aerodynamic shape optimization
• Experience in turbulence modeling, boundary-layer transition, unsteady aerodynamics, and interference aerodynamics
• Strong competence running NASA OVERFLOW and/or FUN3D CFD software (RANS flow solvers)
• Proficiency in 3D surface and volume meshing using structured overset meshes and/or unstructured tetrahedral/hexahedral meshes
• Proficiency in lofting aircraft in 3D CAD software (e.g., CATIA, NX) and applying CAD cleanup tools
• Proficiency in Python and/or MATLAB scripting
• Experience working with external partners and suppliers on development projects
• Familiarity with software development best practices and version control (Git)
• Good knowledge of high-performance computing (HPC) hardware and software
• Strong technical, written, and verbal communication skills
• Ability to work well both collaboratively and independently
• Experience in a fast-paced design environment

• Aerodynamics design experience on a large transport/freighter/cargo category aircraft
• Familiarity with aircraft certification standards (14 CFR Part 25 or Part 23), preferably having been through an airplane development and certification program
• Familiarity with cloud computing platforms
• Experience planning and executing wind-tunnel test campaigns to validate CFD and aerodynamic predictions
• Proficiency in MATLAB
• Experience mentoring junior aerodynamics engineers in CFD
