Principal CFD Engineer - Hydrodynamic Systems

Verterra Energy • New Brighton, MN

4h

About The Position

You will lead computational fluid dynamics modeling efforts for Verterra’s turbine systems and related platforms.
You will define modeling strategy, boundary conditions, mesh approach, turbulence models, and validation methods. You will work directly with mechanical and test engineers to ensure CFD results inform blade geometry, structural loads, fatigue expectations, and overall system efficiency.
We are open to full-time, part-time, or 1099 arrangements for the right subject matter expert.

Requirements

• 8+ years of professional CFD experience (12+ for Principal level)
• Demonstrated experience modeling external fluid flow systems
• Experience with rotating machinery or turbine systems
• Deep understanding of turbulence modeling and numerical stability
• Experience correlating CFD results to physical testing
• Ability to independently define modeling strategy

Nice To Haves

• Marine, riverine, or open-water flow modeling experience
• Experience with cavitation prediction
• Experience modeling debris interaction or multiphase flow
• Experience supporting hardware programs from early prototype through validation
• Experience working in small, engineering-driven teams

Responsibilities

• Develop and execute 3D CFD models of rotating turbine systems in open-water environments
• Model turbulent, unsteady, and cyclic flow conditions
• Support blade and housing geometry optimization
• Evaluate flow separation, wake behavior, cavitation risk, and efficiency tradeoffs
• Define appropriate turbulence models and simulation fidelity
• Develop mesh strategies for rotating machinery and complex geometries
• Establish convergence and validation criteria
• Correlate CFD outputs with experimental data from flume and field testing
• Identify when simulation assumptions break down
• Extract pressure and force distributions for structural loading analysis
• Support fatigue and cyclic loading estimation
• Work cross-functionally with structural and mechanical engineers
• Translate fluid results into manufacturable design recommendations
• Model debris interaction scenarios and flow disturbance cases
• Evaluate performance in variable flow velocities
• Understand long-term exposure considerations in real water systems
• Present results in clear, engineering-driven formats
• Identify design tradeoffs and uncertainty bands
• Support design reviews with defensible analysis
• Document modeling assumptions and limitations

Benefits

• Medical, dental, and vision coverage
• Company-paid life, disability, and basic protection
• 401(k) with employer match
• Unlimited paid time off + 2 weeks sick and safe leave
• 7 company-paid holidays: New Year’s Day (January 1), Memorial Day, Fourth of July, Labor Day, Thanksgiving Day, the Friday after Thanksgiving, and Christmas Day
• Stocked kitchen
• Equal opportunity
