Senior Turbomachinery Engineer - Aero / Flowpath

Senior Turbomachinery Engineer – Aero / Flowpath

Location: US – On-site

Package: Up to $200,000 base + equity / RSUs + comprehensive benefits

Interview process: 3 steps

Right to Work: Unrestricted US work authorisation required

iO Associates is supporting a well-capitalised advanced-mobility hardware business as it expands a small engineering group working on a clean-sheet high-power propulsion programme.

The work is hands-on, 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, leaving you room to go deep on the aero while still influencing the full product.

You will be:

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

You must have:

• Relevant experience designing and analysing 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.
• Enough mechanical awareness to make sound decisions around stress, thermal growth, rotordynamics, bearings, seals and hardware interfaces.
• Evidence that you have supported 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. MATLAB, Python, Simulink, ANSYS, CFX, Fluent, NX, Creo or SolidWorks are all relevant.
• The confidence to work independently, make technical calls and move quickly in a small team.

Useful, not essential: Real-gas or non-air working-fluid experience, cryogenics, cooling systems, pumps, high-temperature materials, small-engine development or a startup/ skunkworks environment.

Apply today for an early interview slot. If you have owned a rotating-machine problem from concept to test, but your background sits outside conventional aero engines, we would still like to hear from you.
