Senior Electro-Permanent Magnetics Engineer

Gram Games; El Segundo (CA); On-site; USD 160,000 - 200,000; Full time

Job summary

GRAM in El Segundo is seeking an Electro-permanent Magnet (EPM) engineer to own the device from magnetic-circuit architecture through pulse-waveform requirements, integration, and life testing. You will ensure holding force, release behavior, and energy use meet specifications across varying conditions.

Responsibilities include designing magnetic circuits, coils, interfaces, and drive electronics; building measurement fixtures; and validating performance with hardware and test data to drive

Qualifications

• Bachelor's degree or equivalent in a relevant engineering field.
• Designed, built, and characterized a permanent-magnet circuit or magnetic latch.
• Built a nonlinear magnetic model and validated with hardware data.
• Hands-on with gaussmeters, oscilloscopes, and data acquisition.
• Documented results and used feedback to improve designs.

Responsibilities

• Translate load cases into holding-force, air-gap, energy, and thermal requirements.
• Design magnetic circuits, pole pieces, switching coils, and sensors.
• Use reluctance models and finite-element analysis to predict flux and force.
• Build fixtures to measure force, flux, waveforms, and coupling.
• Conduct cycling, vibration, and thermal tests to isolate failure modes.
