Senior Design Engineer - Electromagnetic (R&D)

At Apptronik, we are building the next generation of general-purpose humanoid robots designed to change the way we live and work. To achieve unparalleled performance in our robotic platforms, we are expanding our R&D efforts into advanced, custom motor technologies.

Off-the-shelf frameless motors leave significant performance on the table for humanoid robots. As a electromagnetic designer for Apptronik's custom motor program, you will be the driving force behind our next generation of actuators. You will set the target metrics and design the motors to hit them, exploring cutting-edge technologies to maximize performance while ensuring these designs remain viable for mass manufacturing.

In addition to serving as the lead hands-on EM designer, you will act as our primary Subject Matter Expert (SME) when collaborating with external partners, university collaborators, and specialized manufacturing vendors.

Custom Electromagnetic Design & Simulation

• Own the electromagnetic design of custom BLDC/PMSM motors for humanoid joints from concept to built prototype.
• Select and evaluate advanced topologies and approaches
• Run advanced EM simulations (using Ansys Maxwell, Motor-CAD, JMAG, or Altair Flux) to maximize performance.
• Define the trade space between motor, thermal, and robot-level requirements.

Testing, Validation & Characterization

• Specify test requirements and oversee the methodology for characterizing internally developed motors against competing off-the-shelf designs.
• Utilize a motor dyno to close the loop between simulation and hardware, correlating model-to-test data and validating EM simulations empirically.
