Freelance Electrical Motor Control Jobs in Riverside, CA

About the Company
Aerospace is at a turning point — costs are rising, supply chains are strained, and old ways of building can't keep up. We're breaking that mold. We move fast, think big, and combine start-up agility with deep aerospace expertise to design, build, and scale aircraft in ways the industry has never seen. Our team leverages automation, AI-driven tools, and a fully connected digital backbone to accelerate innovation and reduce barriers to production.
Here, you won't just take a job — you'll help reinvent how the world flies. If you're ready to solve complex problems, push technology further, and work alongside some of the brightest minds in aerospace, this is your chance to make a real impact.
About the Role
We're seeking a Senior Motor Control Engineer with deep technical expertise and a passion for building control systems that deliver precision, safety, and reliability. This isn't an "implement the ticket" role — you'll own the control system architecture and lead development of high-performance motor control algorithms for linear and rotary actuators, including the 20 kHz current control loop and velocity/position control running on real-time motor-control microcontrollers.
You'll work hands-on developing, validating, and launching aviation-grade actuation and motor-drive control systems — collaborating closely with Systems, Electrical, and Manufacturing teams to ensure robust integration and certification readiness. This role spans algorithm design, embedded implementation, modeling, calibration, and hardware bring-up, with direct responsibility for performance, robustness, and testability, and the opportunity to see your solutions take flight.
Responsibilities

• Motor Control Algorithms & Architecture
  
• Lead the design and implementation of motor control software for PMSM/BLDC motors
  
• Own FOC-based current control (20 kHz loop), including torque, velocity, and position control
  
• Design and maintain control architecture spanning current, velocity, and position loops
  
• Develop sensor-based FOC, including encoder and current-sensor signal conditioning, plus sensor offset calibration and runtime compensation
  
• Develop and evaluate sensorless control strategies where applicable
  
• Embedded Implementation (TI C2000)
  
• Implement real-time motor control software on TI C2000 microcontrollers (F280039 series or equivalent)
  
• Configure and optimize PWM modules, ADC sampling/synchronization, and interrupt timing for control loop determinism
  
• Develop low-level drivers and middleware as needed for motor control execution
  
• Ensure numerical stability, timing closure, and safe operation across all modes
  
• Modeling & Control Design
  
• Apply model-based design methodologies for control development and validation
  
• Build and maintain motor, inverter, and actuator models across operating conditions
  
• Perform motor parameter identification and estimation to support robust control
  
• Controller Tuning & Calibration
  
• Perform rule-based controller tuning for current, velocity, and position loops
  
• Develop or integrate FOC auto-tuning strategies
  
• Analyze lab data to refine control performance and stability margins
  
• Development, Integration & Test
  
• Support auto-code generation from control models where appropriate
  
• Develop and execute SIL, MIL, and HIL test strategies
  
• Support hardware bring-up, debugging, and system-level integration
  
• Participate in design reviews, code reviews, and requirements definition
  

Qualifications

• 5+ years of experience in motor control software development, with deep hands-on experience in FOC-based motor control
  
• Proven experience implementing motor control on real-time MCUs (TI C2000, NXP, STM32, or similar); direct experience with F28003x/F280039 strongly preferred
  
• Strong foundation in control theory, power electronics, and electric machines
  
• Proficiency in model-based design tools (MATLAB/Simulink or similar) and embedded C/C++ for real-time applications
  
• Experience with SIL/HIL/MIL testing environments and comfort working close to hardware in lab settings
  

Required Skills

• Sensorless motor control algorithms
  
• High-bandwidth current loops (10–20 kHz)
  
• Linear actuator control systems
  
• Auto-code generation workflows
  
• Functional safety or safety-critical systems exposure (DO-178, ISO 26262 concepts)
  
• Aerospace, automotive, or robotics actuation systems background
  

Pay range and compensation package
$150,000–$250,000, based on experience, scope, and internal equity
Eligible for bonus/equity, where applicable
Comprehensive health, dental, and vision coverage
401(k) with company match
Paid time off and holidays
