Turbomachinery Design Engineer

Thermal Systems Department | Ampera Clean Energy

354 Hiatt Dr suite 100, Palm Beach Gardens, FL 33418

About Ampera Clean Energy

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.

Position Summary

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.

Remote Work

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.

Key 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

Required Qualifications

· 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

Preferred Qualifications

· 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

· Candidates should be prepared to discuss or share examples of relevant design work, subject to confidentiality obligations

Why Join Ampera Clean Energy

· Design complex mechanical hardware with meaningful technical ownership

· Work on cutting‑edge clean energy and nuclear technology

· Collaborate in a small, highly technical team where decisions directly shape the hardware

· Make a direct impact on the future of high‑efficiency power generation

Compensation

Compensation: Compensation will be commensurate with the candidate's level, experience, education, and qualifications.

Ampera Clean Energy offers a full benefits package, including a 401(k) match. Relocation assistance may be available based on role level and candidate location.
