Duties and Responsibilities

Control System Design & Simulation
- Design and simulate digital and analog compensators for power converters and motor drives using tools such as Python/NumPy/SciPy, SPICE, and MATLAB/Simulink.
- Perform frequency-domain and time-domain analysis to ensure system stability and robustness.
- Develop analog and digital signal processing systems for feedback conditioning and waveform control.
Implementation & Tuning
- Work with firmware engineers to translate control designs into firmware implementations using C/C++ or model-based code generation.
- Tune control loops in real-time systems, including PID, PI, lead-lag, state space, and nonlinear controllers.
- Support hardware bring-up and debugging of control systems in lab environments.
System Modeling & Analysis
- Create detailed models of power electronic systems including converters, inverters, and motor loads.
- Analyze system dynamics, parasitics, and nonlinearities to improve control performance.
- Collaborate with hardware engineers to co-design control and power stages.
Innovation & Continuous Improvement
- Stay current with emerging control techniques, digital signal processing, and power electronics trends.
- Propose and prototype novel control strategies to improve performance, efficiency, and reliability.
- Document design processes, simulation results, and tuning procedures for knowledge sharing.

Basic Requirements

Bachelor’s degree in Electrical Engineering or Systems and Control Engineering, or related field.
Level II Engineer 3+ years of hands-on, controls engineering experience.
Level III Engineer 5+ years of hands-on, controls engineering experience.
Level IV Engineer 8+ years of hands-on, controls engineering experience.
- Selected candidate's Job Level and Pay Grade will be determined based upon qualifications and experience.
Proficiency in simulation tools such as MATLAB/Simulink, SPICE, PLECS, PSIM, or equivalents.
Strong understanding of control theory, compensator design, system dynamics, and signal processing.
Experience with embedded systems and real-time control applications.
Familiarity with real-time operating systems, digital signal processors, and microcontrollers.
Hands-on experience with lab equipment such as oscilloscopes, frequency response analyzers, spectrum analyzers, and power analyzers.
Excellent problem-solving skills and ability to work in cross-functional teams.
Strong written and verbal communication skills.

Preferred Qualifications

Experience with high power (480V) electrical applications.
Experience with EV charging, welding, or plasma cutting applications.
Familiarity with safety standards and EMI/EMC considerations in controller design.
Experience with FPGA-based control systems or high-speed digital platforms.
