About The Position

Ampera Clean Energy is developing a modular power amplification system that uses nuclear heat input to drive supercritical CO₂ turbomachinery generators. Our work sits at the intersection of advanced rotating machinery, power electronics, thermal systems, and rapid prototyping. We design, build, and test hardware to mature breakthrough energy technology from concept to deployment. Ampera is looking for a Turbomachinery Design Engineer to design and develop radial compressors, radial inflow turbines, and related rotating hardware for advanced energy systems. The role focuses on non-air working fluids such as supercritical CO₂, inert gases, and refrigerants, with responsibility spanning design, analysis, prototyping, and test support. This is a full-time, design-focused engineering role based in Palm Beach Gardens, Florida. The role is eligible for hybrid work, subject to project needs and manager approval. During prototype builds, assembly activities, or test campaigns, extended on-site presence will be required.

Requirements

Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field
Experience designing turbomachinery or other high-speed rotating equipment
Proficiency with SolidWorks or similar CAD tools and experience creating detailed engineering drawings
Working knowledge of CFD, FEA, rotordynamics, or related engineering analysis methods
Ability to support hardware builds, testing, troubleshooting, and design iteration in a fast-moving development environment

Nice To Haves

Hands-on experience with radial compressors, radial turbines, turboexpanders, or similar hardware
Familiarity with non-air working fluids such as supercritical CO₂, inert gases, refrigerants, ORC fluids, or cryogenic fluids
Previous experience with AxStream and/or Ansys turbomachinery workflows

Responsibilities

Design radial compressors, radial inflow turbines, and supporting rotating hardware for supercritical CO₂, inert gas, and refrigerant systems
Develop flow-path and mechanical components including impellers, nozzles, diffusers, shafts, bearings, housings, and seals
Perform engineering analysis using CAD, CFD, FEA, rotordynamics tools, and hand calculations
Create production-ready models, drawings, and documentation, and work with suppliers and manufacturing to release hardware
Support prototype assembly, testing, troubleshooting, and design updates based on test results
Collaborate with thermal, controls, manufacturing, and test teams to integrate turbomachinery into complete systems
