About The Position

AMA is seeking a highly skilled Computational Fluid Dynamics (CFD) Applications Engineer to support aerodynamic, aeropropulsive and flight dynamics analysis using the structured, overset-grid code OVERFLOW for a NASA contract. The successful candidate will apply CFD methodologies to analyze complex electric Vertical Take Off and Landing (eVTOL) vehicles. This role bridges applied aerodynamics and flight dynamics to accurately and efficiently model these vehicles. These simulations will be used to inform flight campaigns and help design control systems.

Requirements

Master’s degree in aerospace engineering, mechanical engineering, or closely related field. A bachelor’s degree and equivalent work experience is acceptable.
Demonstrated proficiency with structured-overset grid generation and running CFD solvers.
Proficiency in scripting and process automation for robust, high-throughput simulation execution.
Experience with steady and unsteady RANS simulations, turbulence modeling, and complex flow phenomena.
Proficiency in Unix environment and high-performance computing systems.
Ability to process and visualize large datasets using relevant tools (Tecplot, ParaView, FieldView, or equivalent).
Excellent problem-solving and analytical capabilities.
Strong written and verbal communication skills.
Ability to work independently while closely collaborating with interdisciplinary teams.
Proven track record of technical documentation and reporting.
U.S. Citizenship or Permanent Residence.

Nice To Haves

Experience with overset grid generation tools like Chimera Grid Tools and Pegasus.
Experience running OVERFLOW for complex rotorcraft applications.
Experience with automated workflow development and parametric studies.
Publications in peer-reviewed journals or conference proceedings related to rotorcraft, eVTOL aerodynamics, or flight dynamics modeling.

Responsibilities

Perform computational fluid dynamics simulations for complex eVTOL vehicles operating across multiple flight regimes (hover, transition, and forward flight).
Develop comprehensive aeropropulsive models to accurately predict forces and moments as functions of many aircraft states and control settings across the full flight envelope.
Generate computationally efficient, moderate-fidelity structured overset grids tailored for the application. Appropriate physical and modeling assumptions should be applied to ensure rapid computation while retaining sufficient accuracy.
Work collaboratively with flight dynamics subject matter experts to develop robust, automated frameworks for prescribing control effector deflections and state variables using statistically designed test matrices.
Assist Dynamics and Control teams to interpret and incorporate CFD results into flight dynamics models and flight control systems.
Analyze and interpret CFD results to provide engineering insights and document analysis methodologies, automated workflows, and results in technical reports and presentations.
Support the development and implementation of best practices for CFD simulation workflows.
