Description

Are you searching for meaningful work as a Thermal/Fluid Modeling and Simulation Engineer to support thermal/aerothermal/aerodynamic engineering for defense applications?

Are you passionate about translating physical phenomena into code and maximizing algorithm efficiency?

If so, we're looking for someone like you to join our team at APL.

We are seeking a highly motivated, technically accomplished engineer/physicist well-versed in computational modeling methodology and analysis to support thermal, aerothermal and infrared scene generation applications in air and missile defense.

Our group has competency in software development supporting infrared (IR) sensor modeling, including all the optical, thermal and time-dependent phenomenology required to simulate and render infrared scenes and signatures with radiometric accuracy for the broad range of exo, endo, and terrestrial scenes that a sensor may observe. This major focus area supports multiple programs, and our work meeting new challenges in thermal and IR modeling is well recognized by our sponsors.

Group expertise also spans high temperature materials and thermal protection systems, ablation and mechanical erosion, and a broad range of thermal analysis supporting design, development, and test of missile and target systems. In aerodynamics and computational fluid dynamics, the group is proficient in modeling across multiple fidelities and software tools for applications that include fluid-structure interactions, reacting and multi-phase flows, and advanced propulsion, as well as subsonic through hypersonic flight regimes.

Currently our strongest need lies in development of thermal and optical simulation software. There are opportunities to support development of modeling software and to engage directly in modeling and analysis, across all of the aforementioned areas of interest. We strive to foster a collaborative team environment where spirited technical discussions spark innovative ideas and out-of-the-box solutions.

As a Thermal/Fluid Modeling and Simulation Engineer on the Aerospace and Thermal Engineering team you may:

  • Use state of the art scientific computing techniques to model phenomena spanning many domains (e.g. fluid dynamics, heat transfer, chemistry, optics)
  • Develop algorithms that translate physics into code using robust and appropriate numerical methods
  • Design, implement, test, and deploy software applications that accurately capture underlying physics while optimizing for efficiency and ease-of-use
  • Work closely with other engineers and physicists to come to solutions for algorithms, program structure and analysis workflow
  • Develop computational models based on theory and empirical data in order to accurately capture phenomena and reduce error margins
  • Seek new and innovative ways to improve algorithm efficiency and document software approaches
  • Support development of thermal protection systems, control surfaces, windows, flight hardware and materials, launch systems, and advanced propulsion systems through model development and/or analysis
  • Design sensitivity/optimization studies and define critical areas of analysis
  • Collaborate across the lab on wide ranging applications ranging from design/testing of advanced propulsion systems to quick-turn analysis supporting warfighter needs
  • Document and present design and analysis results at status meetings and reviews

Qualifications

You'll meet our minimum qualifications if you have...

  • A PhD in mathematics, physics, engineering or related field
  • 1+ years of academic and/or work experience in one or more subject areas relevant to thermal, aerothermal, or aerodynamic modeling and analysis; computational physics of aerodynamics, thermal and optical phenomena, multiband infrared scene and signature modeling, and radio frequency propagation modeling.
  • Proficiency with C++, FORTRAN, or other high performance computing languages
  • Skill in modern software development
  • Familiarity with GPU programming, MATLAB, and/or python
  • Experience creating simulations of real-world phenomena
  • Excellent interpersonal skills, written and oral communication skills
  • A passion for learning and new challenges
  • The ability to obtain a Secret security clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.
