About the role

You are the engineer who sits with the customer. You own the technical relationship with Westmag’s drone OEM customers: design integration, duty-cycle changes, application engineering, and end-of-line validation correlation. You report to the Commercial Team and partner closely with Motor Design.

What you'll own

• The technical relationship with Westmag's drone OEM customers.

• Spec interpretation, application-engineering questions, duty-cycle and thermal trade-offs.

• Customer-witnessed test programs for new motor variants, correlated against Westmag's end-of-line validation data.

• Serve as the first response for field issues, including triage, escalation to design or quality, and customer follow-through.

• Engineering voice for early-stage technical engagements with prospective drone OEMs (BD calls, technical due diligence).

• App-note and reference-design content for the drone-motor product family.

Required qualifications

• BSEE, BSME, or equivalent technical degree.

• 5+ years field/applications engineering or customer-engineering experience at a motor, sensor, drive, or actuator company.

• Familiarity with motor control, VFD, or inverter integration at the customer-system level.

• Customer-facing confidence, written and verbal, at the engineer-to-engineer level.

• Willingness to spend significant time on customer sites (up to 40% travel).

• Must be authorized to work in the United States.

Preferred qualifications

• Direct experience supporting drone, robotics, or aerospace OEM customers.

• Background combining FAE work with end-of-line / dynamometer test correlation.

• Experience authoring application notes and technical white papers.
