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 first‑of‑a‑kind hardware to mature breakthrough energy technology from concept to deployment. Ampera Clean Energy is seeking a Principal Generator Design Engineer (Electromagnetics) to lead the clean‑sheet electromagnetic design of MW-class custom electric generators. This role owns the electrical machine architecture and electromagnetic performance of large rotating generators, from initial concept through hardware testing and model correlation. The ideal candidate has deep expertise in electrical machine theory, hands‑on experience designing large generators from first principles, and the judgment to make architecture decisions that persist through fabrication and test. This is a design‑focused engineering role eligible for hybrid‑remote work at the discretion of the director. During periods of prototype builds, assembly, or test campaigns, extended on‑site presence will be required.

Requirements

Experience designing electric motors or generators from concept to hardware release
Direct experience with large rotating machinery (multi‑MW preferred)
Bachelor’s degree or higher in Electrical Engineering or closely related field
Proficiency with SolidWorks or equivalent CAD tools
Strong working knowledge of Microsoft Office (Excel, Word, PowerPoint, Outlook, Teams)
Experience supporting hardware testing in industrial, aerospace, energy, or heavy manufacturing environments

Responsibilities

Lead clean‑sheet design of MW-class electric generators, including topology selection (synchronous, permanent magnet, or hybrid architectures)
Perform electromagnetic design and analysis, including: Stator and rotor configuration, Winding design and insulation systems, Magnetic materials selection, Loss modeling (copper, core, windage, stray)
Define electrical performance requirements including voltage, current, efficiency, thermal margins, and transient behavior
Perform detailed electromagnetic analysis using analytical methods and numerical tools
Model and predict: Copper, core, stray, and windage‑related electromagnetic losses, Flux distributions, saturation behavior, and thermal loss inputs
Correlate electromagnetic models to test data and drive iterative design improvement
Define electrical loss breakdowns and thermal inputs for cooling system design
Specify allowable temperature limits, margins, and operating derates from an electrical perspective
Define electrical interface requirements for mechanical and structural teams, including
Collaborate closely with mechanical and thermal engineers while retaining clear EM ownership
Define electrical instrumentation and measurements for generator testing
Support electrical testing, data acquisition, and validation activities
Analyze test results, validate models, and refine electromagnetic designs
