About the job
Develops and validates electric-motor models and tests to guide motor design and optimization across Zipline aircraft, accounting for aircraft-level performance.
What you'll do
- Build and maintain electromagnetic, performance, loss, and reduced-order motor models and design-space datasets.
- Plan and run dynamometer tests, correlate experimental results with models, and improve model accuracy.
- Integrate motor models with aircraft, inverter, battery, thermal, controls, and driven-load models to inform system-level design decisions.
What they ask for
- Master’s degree or PhD in electrical engineering, mechanical engineering, applied physics, or a related field, focused on electric machines, electromagnetics, optimization, or electric powertrains.
- Strong electric-machine fundamentals and significant experience developing and interpreting finite-element and reduced-order models.
- Experience with Motor-CAD or similar software and strong proficiency in MATLAB.
- Hands-on experience planning and executing motor dynamometer tests, defining measurements, and correlating models against test results.
Nice to have
- Experience in aerospace, electric aviation, robotics, automotive traction, or other mass- and efficiency-constrained applications.
- Experience with optimization, uncertainty quantification, surrogate modeling, or machine-learning-assisted design exploration.
