Senior Turbomachinery Engineer - Aero / Flowpath

Location: US - On-site
Right to Work: Unrestricted US work authorization required

About the role

We are expanding a small engineering group working on a clean-sheet high-power propulsion program. This is a hands-on role for an engineer who wants to own the flowpath, not just run CFD on one portion of a large legacy engine. You will be close to the rotating hardware, the test setup, and the design decisions that determine what is built next.

You will take responsibility for the aero development of compact rotating machinery, working from early sizing and stage matching through detailed analysis, hardware release, and test correlation. The wider team covers structures, rotating systems, and integration, allowing you to focus deeply on aero while still influencing the full product.

Responsibilities

• Own compressor/turbine flowpath design, map work, and off-design performance across radial, centrifugal, and axial architectures.
• Use 1D, throughflow, and 3D methods to drive stage performance, operability, losses, clearances, and thermal-mechanical trade-offs.
• Work with the mechanical team on rotating kit, bearings, seals, tip-clearance control, packaging, and producibility.
• Support CAD layout, supplier discussions, and the transition from analysis into buildable prototype hardware.
• Get hands-on with cold-flow rigs, instrumentation, DAQ, and test correlation, then turn data into the next hardware revision.
• Improve internal tools and engineering workflows to keep a fast hardware program moving.

Requirements

• Relevant experience designing and analyzing turbomachinery: compressors, turbines, turbochargers, turbopumps, expanders, or comparable high-speed rotating equipment.
• Strong 1D / 2D / 3D aero capability, including mean-line or throughflow methods and practical CFD experience.
• Mechanical awareness to make sound decisions around stress, thermal growth, rotordynamics, bearings, seals, and hardware interfaces.
• Evidence of supporting hardware through build, rig test, data reduction, and design iteration—not only desktop analysis.
• Experience with a mix of CFD, FEA, CAD, and engineering scripting tools (e.g., MATLAB, Python, Simulink, ANSYS, CFX, Fluent, NX, Creo, SolidWorks).
• Confidence to work independently, make technical calls, and move quickly in a small team.

Nice to have

• Real-gas or non-air working-fluid experience, cryogenics, cooling systems, pumps, high-temperature materials, small-engine development, or a startup/skunkworks environment.

Benefits

• Up to $200,000 base salary
• Equity / RSUs
• Comprehensive benefits
