Job Summary

We are seeking an experienced Internal Aerodynamics and Thermal Engineer to join our Flight Technologies Department at General Atomics Aeronautical Systems, Inc. (GA-ASI). As a key member of our team, you will contribute to the development and implementation of novel thermal management solutions for both conceptual and production aircraft.

Key Responsibilities
  • Support the development of thermal systems, including system architecture definition, thermal system modeling, component sizing, and design in collaboration with peer technical teams.
  • Perform trade studies relating to the selection of material and subsystem hardware.
  • Identify feasible thermal architectures and mature designs through conceptual, preliminary, and detailed design phases using practical passive and active thermal control techniques.
  • Develop and analyze steady state & transient system level thermal models to predict thermal loads, impacts, and temperature margins to support system design, including relevant tool development and automation.
  • Develop vehicle-level CFD thermal models using Fluent or Star-CCM+ and develop and analyze steady state & transient models for liquid cooling systems used to size and optimize coolant pumps and heat exchangers for airborne applications.
  • Develop and support thermal verification testing on aircraft systems and components, including test design, test conduct, data reduction, analysis, and reporting.
  • Brief design and analysis materials to internal and external customers.
  • Provide engineering support for thermal management hardware procurement, planning, procedural & operations.
  • Mentor and support junior engineers.
  • Assist in proposal and new business development efforts.
Requirements
  • Typically requires a bachelor's degree, master's degree, or PhD in engineering or a related technical discipline from an accredited institution and progressive engineering experience as follows: twelve or more years of experience with a bachelor's degree, ten or more years of experience with a master's degree, or seven or more years with a PhD.
  • Relevant experience in Thermal or Fluids analysis in Aerospace, Automotive, or another relevant industry.
  • Strong understanding of heat transfer and fluid mechanics/dynamics fundamentals, design, analysis, and processes related to aerospace thermal management systems.
  • Fundamental knowledge of vapor compression systems, air cycle systems, and ram cooled technologies and their application to aircraft environmental control systems.
  • Familiarity with thermal and liquid system components (e.g., valves, regulators, heat exchangers, and pumps for fuel, coolants, and other fluids).
  • Demonstrated anchoring of first-principles models to higher-fidelity simulations and test data.
  • Familiarity with industry standard aerospace thermal and environmental control system design requirements including MIL-HDBK-310 and MIL-STD-810.
  • Direct experience in any of these technical areas: 3D Surface and Volume Meshing (ANSA preferred), Computational Fluid Dynamics (CFD), Heat Transfer/Thermal Analysis & Simulation, Numerical Methods, High Performance Computing, and/or Test Validation.
  • Effective in contributing in a structured, cross-functional team-oriented environment.
  • Ability to obtain and maintain DoD security clearance is required.
Preferred Qualifications
  • Advanced degree in Mechanical or Aeronautical Engineering related to heat transfer and fluid mechanics from an accredited college or university.
  • 8+ years of relevant proven experience in design, analysis, and test of aircraft thermal systems.
  • Demonstrated experience with sizing vapor compression systems, air cycle systems, and ram cooled technologies and integration into aircraft environmental controls systems.
  • Demonstrated experience with sizing and selection of liquid cooling system components (e.g., valves, regulators, heat exchangers, and pumps for fuel, coolants, and other fluids).
  • Expert using industry-standard CFD tools like FUN3D, Fluent, Thermal Desktop, or Star-CCM+, including use of HPC clusters.
  • Experience designing/implementing/debugging/testing computer code (e.g., Python, MATLAB, C++, etc.).
  • Active Secret or Top-Secret Security clearance.
Benefits

We offer a competitive salary range of $116,480 - $208,505, with a hybrid work style and relocation assistance provided. US citizenship is required for certain positions, and a DoD security clearance is required. We are an Equal Opportunity/Affirmative Action Employer and welcome all qualified individuals to apply.
