Job Summary:

General Atomics Aeronautical Systems, Inc. (GA-ASI), an affiliate of General Atomics, is a world leader in proven, reliable remotely piloted aircraft and tactical reconnaissance radars, as well as advanced high-resolution surveillance systems.

We have an exciting opportunity for a Thermal- and Fluid-Systems Analysis Engineer in the San Diego (Poway, CA) area. In this role, you will contribute directly to the design, analysis, and development of propulsion and thermal management systems for next-generation unmanned aircraft platforms. Responsibilities include leading CFD analyses of internal combustion engines and aircraft fluid systems, developing performance models in MATLAB/Simulink, supporting engine integration and cooling system design, and conducting thermal and fluid system trade studies. This position offers competitive benefits, including 9/80 work schedule, medical, dental, employer-matched 401(k), pension plan, employee referral program, and more.

DUTIES AND RESPONSIBILITIES:

Lead CFD studies of internal combustion engines, intake/exhaust systems, and propulsion-airframe integration using CONVERGE or similar tools
Develop and maintain MATLAB/Simulink models for engine performance, thermal management systems, and aircraft fluid systems
Analyze air cooling, liquid cooling, and fuel system architectures to support conceptual, preliminary, and detailed design phases
Perform thermal and fluid system trade studies to optimize cooling effectiveness, weight, and integration complexity
Conduct transient and steady-state simulations to evaluate system performance across the flight envelope
Define appropriate modeling strategies and fidelity levels for propulsion and thermal systems across program maturity
Support engine test planning, execution, and correlation of analytical predictions to experimental data
Collaborate with airframe, structures, and flight controls teams to ensure integrated system performance
Contribute to internal toolchain development, workflow automation, and advanced modeling capability
Participate in internal and customer-facing design reviews, test readiness reviews, and technical meetings
Contribute to a broad swath of novel remotely-piloted aircraft platforms

We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.

Job Qualifications:

Typically requires a bachelors degree, masters 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 bachelors degree, ten or more years of experience with a masters degree, or seven or more years with a PhD. May substitute equivalent engineering experience in lieu of education.
Strong programming proficiency in Python and MATLAB for scientific computing and workflow automation
Security Clearance is desirable
Demonstrated ownership of complete CFD workflows, including CAD preparation, mesh generation, solver setup, convergence assessment, and results post-processing
Strong foundational understanding of heat transfer, fluid mechanics, turbulence modeling, and numerical methods
Experience with aircraft fluid systems design and analysis, including air cooling, liquid cooling, and fuel systems
Solid understanding of internal combustion engine fundamentals, including piston engines, thermodynamic cycles, combustion processes, and performance characteristics
Strong proficiency in MATLAB/Simulink for system-level modeling and simulation
Demonstrated applied experience using CFD tools such as CONVERGE, STAR-CCM+, ANSYS Fluent, or similar for internal combustion engine analysis
Ability to obtain and maintain a DOD Security Clearance is required.

PREFERRED SKILLS AND EXPERIENCE:

Experience with engine-airframe integration and propulsion system installation design
Experience developing reduced-order models or control-oriented models for real-time simulation
Familiarity with 1D system modeling tools (e.g., GT-SUITE, AMESim, Ricardo WAVE)
Experience with experimental engine testing, instrumentation, and data correlation
Demonstrated validation, verification, and uncertainty quantification (UQ) of propulsion system models
Experience with optimization methods applied to thermal management or propulsion system design
Knowledge of aircraft electrical systems and hybrid-electric propulsion architectures
Experience contributing to production-quality engineering software using modern development practices
