Permanent Ran Optimization Engineer Jobs in Utah

Position Summary

We are looking for a Propulsion Engineer to join our propulsion systems team. You will participate in the development, optimization, and testing of high-performance brushless motor systems that drive the core functionality of our UAVs. This may include ESC design, current/voltage regulation, and efficient propeller-motor integration. Your work will directly impact flight stability, energy efficiency, and system reliability.

Essential Duties and Responsibilities

• Motor Control Development
  • Participate in selection and validation of motor drivers, MOSFETs, current sensors, and gate drivers for high-efficiency operation.
• Power Electronics & ESC Design
  • Design and test ESCs tailored to drone propulsion systems with an emphasis on thermal performance, switching frequency optimization, and EMI reduction.
  • Work with PCB designers to develop compact, thermally-managed layouts for power electronics boards.
• System Integration & Performance Tuning
  • Participate in Integration of motors and controllers into UAV platforms, optimizing thrust-to-weight ratio and dynamic response.
  • Participate in Tuning PID and control loop parameters for flight stability and minimal latency.
  • Analyze power draw, efficiency curves, and torque-speed characteristics across flight envelopes.
• Testing, Validation & Failure Analysis
  • Set up and run bench and flight tests to measure thrust, RPM, current draw, and heat dissipation.
  • Use oscilloscopes, current probes, and data loggers to debug and refine system behavior.
  • Perform root cause analysis of electrical or mechanical failures in motor systems and recommend design changes.
• Cross-Functional Collaboration
  • Work closely with mechanical engineers on propeller sizing, vibration mitigation, and mount design.
  • Coordinate with flight control and embedded systems teams to ensure compatibility between propulsion and control logic.
  • Contribute to motor safety features, redundancy strategies, and startup/shutdown sequencing.

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering or Mechatronics.
• 4+ years of experience in BLDC motor control design and implementation.
• Strong knowledge of FOC, PWM generation, sensorless/sensored feedback systems.
• Experience on STM32, TI, or similar MCUs.
• Experience with power electronics design and hardware debugging tools (oscilloscope, logic analyzer, etc.).
• Familiarity with UAV systems or robotics platforms.

Additional Desired Qualifications

• Experience with high-frequency switching and thermal design in compact UAV ESCs.
• Familiarity with drone-specific motor testing, thrust stands, and performance tuning methods.
• Simulation experience using MATLAB/Simulink or PLECS for motor dynamics.
• Knowledge of EMI/EMC design practices and compliance testing.

Physical Requirements and Working Conditions

• Hands-on lab testing, prototyping, and field validation.
• Occasional outdoor flight testing and iterative hardware development.
• Team-based development in an agile engineering environment.
