Purpose

Lincoln Electric is seeking a skilled and motivated Controls Engineer to join our R&D team. This role will focus on the simulation, design, and tuning of digital and analog control systems for power electronics and motor controls in welding, cutting, and EV charging applications. The ideal candidate will have a strong background in Electrical Engineering and Controls Engineering and will contribute to the design of advanced control algorithms, compensator designs, and system-level models to enhance product performance and stability.

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/Num Py/Sci Py, 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.
