Principal Electrical Machine Design Engineer — MW-Class Generators

Principal Electrical Machine Design Engineer — MW-Class Generators
Location: South Florida, USA
Work Model: Hybrid / on-site during build and test campaigns
Compensation: Up to $200,000 base salary, plus a strong equity package
Relocation: Paid relocation available for the right candidate
About the Company

A confidential advanced energy technology company in South Florida is developing next-generation power generation hardware at the intersection of electric machines, turbomachinery, thermal systems, power electronics, and rapid prototyping.
The company is building a modular power amplification system that uses high-temperature heat input to drive supercritical CO₂ turbomachinery and MW-class electric generators. This is first-of-a-kind hardware work: clean-sheet design, rapid iteration, prototype builds, physical testing, and model correlation.
This is an opportunity to take real ownership of a critical electrical machine architecture and help shape a breakthrough clean energy platform from concept through test and deployment.
The Role
We are hiring a Principal Electrical Machine Design Engineer — MW-Class Generators to lead the electromagnetic design of custom, high-power rotating generators.
This person will own the electrical machine architecture, electromagnetic performance, and design trade space for MW-class generator hardware. The work spans topology selection, winding design, loss modeling, material selection, thermal interface definition, instrumentation planning, hardware testing, and test-data correlation.
The ideal candidate has designed motors or generators from first principles, understands large rotating machinery, and has the engineering judgment to make architecture decisions that survive fabrication, assembly, and test.
What You Will Own
Generator Architecture & Electromagnetic Design
Lead clean-sheet electromagnetic design of MW-class electric generators.
Select and evaluate machine topologies, including synchronous, permanent magnet, wound-field, and hybrid architectures.
Define stator and rotor configurations, winding layouts, insulation systems, voltage class, current levels, efficiency targets, and operating margins.
Develop performance models for steady-state and transient operation.
Make first-principles design decisions that balance electromagnetic performance, manufacturability, thermal limits, mechanical constraints, and test risk.
Electromagnetic Modeling & Loss Analysis
Build analytical and numerical electromagnetic models to predict generator performance.
Model copper loss, core loss, stray loss, windage-related effects, saturation behavior, flux distribution, and thermal loss inputs.
Use simulation and hand calculations to guide design tradeoffs before committing to hardware.
Correlate electromagnetic models against test data and update design assumptions based on measured performance.
Thermal, Mechanical & System Interfaces
Define electrical loss breakdowns and thermal inputs for the cooling system.
Specify allowable temperature limits, derates, insulation margins, and operating constraints from an electrical machine perspective.
Provide electrical interface requirements to mechanical, thermal, structural, and power electronics teams.
Collaborate closely across disciplines while maintaining clear ownership of generator electromagnetic design.
Prototype Build, Instrumentation & Test
Define electrical instrumentation, measurements, and validation plans for generator testing.
Support prototype assembly, bring-up, data acquisition, and troubleshooting.
Analyze test results, identify performance gaps, and drive design improvements.
Help transition designs from concept to hardware release and repeatable test campaigns.
Required Qualifications
Experience designing electric motors, generators, or other electrical machines from concept through hardware release.
Strong understanding of electromagnetic machine theory, rotating machinery, winding design, magnetic materials, insulation systems, and loss modeling.
Direct experience with large rotating machinery; multi-MW generator or motor experience is strongly preferred.
Bachelor’s degree or higher in Electrical Engineering or a closely related technical field.
Experience supporting hardware testing in industrial, aerospace, energy, automotive, defense, heavy manufacturing, or similar environments.
Ability to work across electromagnetic, thermal, mechanical, manufacturing, and test disciplines.
Proficiency with CAD or engineering design tools such as SolidWorks or equivalent.
Strong working knowledge of technical documentation, analysis, and communication tools.
Strong Plus Qualifications
Experience with MW-class generators, high-speed generators, turbomachinery-driven generators, or custom rotating electrical machines.
Experience with permanent magnet machines, wound-field synchronous machines, axial flux machines, radial flux machines, or hybrid machine architectures.
Experience with electromagnetic FEA tools such as Ansys Maxwell, Motor-CAD, JMAG, Flux, COMSOL, or equivalent.
Familiarity with generator cooling, insulation life, high-voltage design, vibration considerations, rotor dynamics, bearings, or power electronics interfaces.
Experience in startup, R&D, prototype, lab, or first-of-a-kind hardware environments.
Why This Role Is Different
This is not a sustaining engineering role and it is not a narrow simulation-only position. The person in this seat will have meaningful technical ownership over the generator design from early architecture through build, test, and iteration.
You will help design multi-megawatt electrical machines for an advanced clean energy system and work directly with a small, highly technical team where engineering decisions quickly become hardware.
What We Offer
Base salary up to $200,000, depending on experience.
Strong equity upside in an early-stage advanced energy company.
Paid relocation to South Florida for the right candidate.
High technical ownership over critical generator architecture.
Hands-on work with advanced turbomachinery, thermal systems, power electronics, and first-of-a-kind clean energy hardware.
A small, focused engineering team where strong technical judgment matters.
Location & Work Model
This role is based in South Florida. Hybrid work may be available depending on project phase and team needs, but candidates should expect significant on-site presence during prototype builds, assembly, integration, and test campaigns.
Paid relocation is available for qualified candidates who are not currently located in South Florida.
How to Apply
Interested candidates should submit a resume highlighting relevant experience in electric machine design, generator design, electromagnetic analysis, rotating machinery, MW-class hardware, prototype testing, and first-principles engineering.
