Job summary

Blue Origin Engines seeks an experienced CFD engineer to design, analyze, and optimize CFD models predicting thermal environments and structural loading in combustion devices and turbomachinery. You will anchor CFD results to test data and collaborate with thermal and structural analysts to ensure integrated predictions across the engine operating envelope.

5+ years of CFD in propulsion, proficiency with major CFD tools, and strong fundamentals in fluid mechanics and heat transfer are required.

Qualifications

• B.S. degree in Mechanical or Aerospace engineering.
• Minimum 5 years CFD experience in combustion systems, turbomachinery, or related engine systems.
• Proficiency with CFD codes (ANSYS Fluent/CFX, Star-CCM+, OpenFOAM).
• Solid understanding of fluid mechanics and heat transfer.
• Experience deriving thermal and pressure boundary conditions for downstream FEA.
• Familiarity with mesh generation for complex 3D geometries.
• Experience with scripting for pre/post-processing (Python, MATLAB, Fortran, VBA).
• U.S. citizen or eligible to work in the U.S.

Responsibilities

• Develop, execute, and maintain CFD models to predict thermal environments and loads on combustion devices and turbomachinery components.
• Generate high-fidelity predictions of flow fields and temperatures to support design decisions.
• Derive CFD-based boundary conditions for use by thermal and structural analyses.
• Collaborate with thermal and structural analysts for integrated predictions.
• Anchor CFD predictions to engine/test data and drive model improvements.
• Support test plan development to verify thermal requirements.
