Job description

We are seeking a Sr. Turbomachinery Aerodynamics Engineer to define operating characteristics and design high-performance flowpaths, airfoils, and inlet/outlet geometries for a supercritical CO₂-based power cycle. This role involves CFD modeling, aerodynamic optimization, and experimental validation to enhance turbomachinery efficiency and operability. The ideal candidate has expertise in compressible flow, turbomachinery aerodynamics, and cycle performance analysis, with experience in both simulation and testing environments.

Arbor is a team of engineers, scientists, and builders focused on creating the next generation of clean energy systems. Our work combines high-efficiency turbomachinery, advanced combustion, and modular design to deliver zero-emission, fuel-flexible power at scale. We’ve drawn from aerospace and industrial expertise to meet the challenge of surging electricity demand—and to offer a solution that installs faster, performs better, and costs less than conventional alternatives. We’re designing energy systems that can evolve with the world’s needs.

Responsibilities

• Define turbomachinery operating characteristics for a supercritical CO₂ power cycle.
• Design and optimize flowpaths, airfoils, and inlet/outlet geometries for compressors and turbines.
• Develop and run CFD simulations to assess aerodynamic performance and flow behavior.
• Analyze secondary flows, losses, and flow stability to improve efficiency and operability.
• Collaborate with mechanical, thermal, and structural engineers to integrate aerodynamic designs.
• Support the development of test plans, instrumentation strategies, and data validation.

Requirements

• Bachelor’s degree in Aerospace, Mechanical, or a related Engineering field.
• 6+ years of experience in turbomachinery aerodynamics or aerodynamic design.
• Proficiency in CFD tools (ANSYS Fluent, CFX, STAR-CCM+, OpenFOAM, or similar).
• Strong understanding of compressible flow, boundary layers, and fluid-structure interactions.
• Experience designing airfoils, flowpaths, and gas path geometries for turbines or compressors.

Preferred Qualifications

• Experience designing turbomachinery throughout the product lifecycle, from concept to validation.
• Familiar with supercritical CO₂ cycles or high-density working fluids.
• Experience with Concepts RITAL/Concepts COMAPL/Concepts AxCent.
• Proficiency in NX CAD software.
• Experience in startup or R&D environments.

Benefits

• Stock options
• Medical, dental, and vision insurance (Arbor covers 90% for employees)
• Basic life insurance fully covered
• Health savings account (HSA) with matching
• Flexible savings account (FSA)
• Unlimited PTO
• 12+ company holidays, including Earth Day!
• 401(k)
• Commuter benefits
• Annual learning and development stipend
• And more!

Salary: $160,000 - $180,000 a year, subject to the applicant's skills, qualifications, and experience.
