About the Job

Requirements

  • Possess a bachelor's degree in Aerospace Engineering, Mechanical Engineering, Physics, or a related field.
  • Have a strong foundation in fluid mechanics, compressible flow, thermodynamics, combustion, numerical methods, or computational fluid dynamics (CFD).
  • Have applied computational methods through employment, research, internships, laboratory work, or substantial academic projects.
  • Have familiarity with CFD, including meshes, boundary conditions, numerical methods, and physical models.
  • Have an interest in scramjet, dual-mode ramjet, or other high-speed propulsion systems.
  • Have basic experience with Linux and a programming or scripting language such as Python, MATLAB, C++, or Fortran.
  • Be able to work through unfamiliar problems, ask productive questions, and assess whether an answer is physically credible.
  • Possess strong written and oral communication skills.
  • Be motivated to learn and able to work both independently and as part of a multidisciplinary team.
  • Be able to obtain an Interim Secret clearance by the start date and ultimately obtain a Secret clearance; eligibility requirements include U.S. citizenship.

Responsibilities

  • Support the design and analysis of scramjet inlet, isolator, combustor, and nozzle flowpaths.
  • Apply CFD to compressible and reacting-flow problems.
  • Create and evaluate computational meshes for internal-flow and integrated-vehicle geometries.
  • Execute and post-process simulations using finite-rate chemistry and appropriate physical models.
  • Examine mesh sensitivity, numerical convergence, boundary conditions, and modeling assumptions.
  • Compare computational results with experimental data, analytical results, and engineering models.
  • Investigate unexpected results and develop possible physical explanations.
  • Build scripts and workflows for simulation setup, data processing, and visualization.
  • Document and present methods, assumptions, results, and conclusions.
  • Take increasing ownership of technical problems as experience develops.

Desired Qualifications

  • Possess a master's degree focused on propulsion, combustion, compressible flow, hypersonics, or CFD.
  • Have one to three years of relevant professional, internship, or research experience.
  • Have worked on scramjets, ramjets, rocket propulsion, reacting flows, or high-speed aerodynamics.
  • Have applied CFD to compressible or reacting flows using finite-rate chemistry.
  • Have performed mesh-refinement, sensitivity, verification, or validation studies.
  • Have compared computational results with experimental or analytical data.
  • Have introductory experience with large eddy simulation, hybrid Reynolds-averaged Navier–Stokes/large eddy simulation, high-performance computing, or automated simulation workflows.
  • Have experience with relevant CFD, meshing, post-processing, or combustion-analysis tools.
  • Have an active Secret clearance.

About the Company

Johns Hopkins Applied Physics Laboratory

Not-for-profit UARC delivering national security research

Johns Hopkins Applied Physics Laboratory (APL) is a not-for-profit university-affiliated research center that provides solutions to complex national security and scientific challenges through technical expertise, prototyping, research and development, and analysis. It uses engineering, simulations, and studies to design prototypes and deliver analyses that support government and partner organizations. Unlike many commercial firms, APL operates as a non-profit affiliated with Johns Hopkins and focuses on mission-oriented research rather than selling finished products. Its goal is to provide practical, thoroughly tested solutions to public-sector customers by performing research, developing prototypes, and offering expert analysis.
