What are the responsibilities and job description for the Motor Manufacturing Engineer position at Powerus?
About Powerus
Powerus is building a next-generation American autonomous systems platform designed to move, protect, and sustain critical assets in high-consequence environments. The company combines advanced autonomy, manufacturing capability, operational expertise, and strategic acquisitions to support defense, national security, critical infrastructure, and commercial operations globally.
Mission
Our mission is to deliver resilient autonomous technologies that strengthen national security, improve operational safety, and expand the capabilities of organizations operating in complex environments.
Why Join Powerus
Every Powerus aircraft uses brushless DC motors, and motor supply limits production rate. Powerus is bringing motor winding, assembly, and test in-house at Rock Hill.
This role stands up that capability: equipment selection, process development, and end-of-line test. Motor design remains with propulsion engineering; this role makes the design producible at rate.
Position Overview
Powerus is seeking a Motor Manufacturing Engineer to establish and improve production processes for brushless DC motors used in autonomous aerial systems. The role covers stator winding, magnet bonding, rotor balancing, final assembly, and end-of-line electrical and performance test.
Key Responsibilities
- Develop and document manufacturing processes for stator winding, magnet bonding, rotor balancing, and motor assembly
- Specify, procure, and qualify winding, bonding, balancing, and test equipment
- Define end-of-line test methods for back-EMF, resistance, insulation, vibration, and performance
- Analyze production and test data to improve yield and consistency
- Lead root cause analysis on motor failures from production, test, and field returns
- Work with propulsion engineering on design for manufacturability
- Qualify motor and magnet suppliers with supply chain and quality
- Write work instructions and train production technicians
Qualifications
- Must be located in the United States, within commuting distance of Rock Hill, SC
- Bachelor's degree in mechanical, electrical, or manufacturing engineering, or equivalent practical experience
- Experience manufacturing electric motors or electromechanical assemblies
- Working knowledge of brushless DC motor construction and operation
- Experience with winding, bonding, potting, or balancing processes
- Experience defining production test procedures
- Experience applying root cause analysis and corrective action
- U.S. Person status required (U.S. citizen, lawful permanent resident, or protected individual under 8 U.S.C. 1324b(a)(3)); this role involves access to ITAR- and EAR-controlled technical data
Preferred Qualifications
- Experience with UAS, e-mobility, or aerospace motors
- Experience with motor dynamometer testing
- Experience with adhesives and magnet handling
- Experience with statistical process control
- Experience scaling a process from prototype to production
- Active or prior U.S. security clearance
What We Look For
Direct experience on a motor or electromechanical production line is required. Candidates should be prepared to describe specific failure modes, such as winding defects, magnet adhesion failures, or imbalance, and the process changes that eliminated them.
