On-siteSeattle, Washington, United States
Job Summary
Lead Aero-Thermal Design by owning the design and optimization of turbines and pumps for power generation cycles. Conduct high-fidelity 3D CFD analysis and structural FEA to ensure component performance and reliability. Use 1D/2D modeling tools for rapid sizing, trade studies, and system-level integration. Lead test campaigns to validate turbomachinery performance, correlate analytical models with experimental data, and identify failure modes. Integrate rotors, housings, bearings, and seals into robust, field-ready assemblies. Establish internal modeling processes, design standards, and documentation to enable the team to scale.
Required Qualifications
- Bachelor's degree in Mechanical or Aerospace Engineering
- 3+ years of experience in the design, analysis, and testing of high speed rotating machinery (pumps, compressors, or turbines)
- Strong fundamentals in thermodynamics, fluid mechanics, and heat transfer
- Experience with CAD software (e.g., Siemens NX) and rapid prototyping
- Ability to thrive in a fast-paced, 'scrappy' startup environment
Desired Qualifications
- Master's or PhD
- Experience with turbomachinery design tools such as AxStream, CFTurbo etc.
- Proficiency in CFD and numerical simulation tools (e.g., ANSYS CFX/Fluent, OpenFOAM, or Numeca)
- Experience with supercritical CO2 or organic Rankine cycle (ORC) turbomachinery
- Knowledge of high-pressure seal design and rotor dynamics
- Hands-on experience setting up and operating high-speed rotating equipment test rigs
- Programming skills (Python, MATLAB, or C++) for automated design optimization and data analysis
