About the Role
As a Senior CFD Engineer with deep expertise in Turbomachinery, you will be a problem solver and builder passionate about creating practical solutions that enable customers to make better engineering decisions. Your focus will be on delivering accurate, insight-driven CFD analyses to support the design, optimization, and performance improvement of rotating machinery. You will excel at working directly with customers, often on-site, to build CAE models integrated into AI-tools that are both useful and used.
Responsibilities
- Leading the design of turbomachinery components on jet engines, including axial and centrifugal compressors from concept through detailed design that balance aerodynamic efficiency, operability, and mechanical constraints.
- Developing and executing coupled aero-thermal, aero-acoustic, and aero-mechanical CFD simulations for airfoil and flowpath geometry optimization.
- Building robust parametric CAD models of turbomachinery blades (e.g. NX, Ansys Bladegen) coupled with simulation pipeline automation.
- Developing and applying 1D meanline models to establish preliminary designs, generate performance maps, and validate against higher-fidelity simulations (e.g. Concepts NREC).
- Partnering with customers to address their most complex engineering challenges through advanced CAE & AI solutions; presenting results clearly, recommending actionable next steps, and balancing accuracy with efficiency under tight deadlines.
- Working at the intersection of CAE and Data Science to generate high-quality simulation datasets for training Machine/Deep Learning models.
- Leveraging data sampling techniques to efficiently capture the design space, reduce computational cost, and enhance model accuracy.
- Accelerating high-fidelity modeling by using the PhysicsX cloud platform and on-premise HPC resources, going beyond smart meshing and model setup to achieve real performance gains.
- Combining project leadership with a strong commitment to mentoring junior colleagues, contributing to a culture of collaboration, growth, and shared success.
- Traveling globally (North America, Europe, Asia, Oceania) up to 2–3 weeks per quarter to work side-by-side with customers in building solutions on-site.
Requirements
- Deep expertise in fluid mechanics, heat transfer, and turbulence modeling, with a solid ability to apply fundamental knowledge to real-world phenomena across a wide range of engineering applications.
- 3-5 years of industry experience (post Masters or PhD) in a commercial, non-research environment.
- Confidence in setting up CFD simulations independently, interpreting complex results with depth, and making informed decisions based on solid engineering judgment.
- Highly proficient in at least one of Star-CCM+, ANSYS Fluent/CFX, or Numeca FINE™ and adept at automating these tools to create reusable workflows for design optimization and DoE studies using MDO tools (e.g., modeFRONTIER/ESTECO, Siemens HEEDS) via APIs or scripting.
- Strong expertise in meshing of turbomachinery blades and rotating components (e.g., Numeca AutoGrid, Ansys Turbogrid) or similar high-end turbomachinery meshing workflows.
- Coding experience (e.g., Python, MATLAB, Fortran) or the ability to quickly learn programming languages, is an advantage.
- US citizens only due to the nature of aerospace and defense work.
