Job Description

Position Title: Control Systems Engineer
Department: Engineering
Reports To: Engineering Manager

Position Summary:

The Control Systems Engineer, as part of a cross-functional team, will be responsible for designing, debugging, characterizing, and releasing control systems for power conversion equipment, including rectifiers, converters, and inverters. The role will focus on developing control algorithms, optimizing software in C programming, and conducting extensive laboratory work to analyze and improve power electronic hardware performance. The power conversion equipment ranges from 3.5 kVA to 250 kVA in power.

Principal Duties and Responsibilities:

Design, develop, and implement control algorithms and software for power electronics, including rectifiers, converters, and inverters.

Perform testing, verification, and troubleshooting of control algorithms and software on power conversion hardware.

Develop specifications and requirements for control software in relation to the electrical characteristics of power conversion equipment.

Document the algorithm and software development process within relevant software tools.

Create and maintain written reports documenting laboratory testing processes and results.

Develop and improve validation plans for evaluating control software performance within power conversion equipment.

Integrate control software with other software functions within the power conversion equipment.

Stay informed on the latest developments in control systems theories, techniques, and technologies.

Education and Experience Requirements:

BS Degree in Electrical Engineering from an ABET-accredited institution (MS preferred).

3-5 years of related experience in power electronics engineering and applying control systems theory.

Strong knowledge of control system theory and its applications, including system modeling and simulation.

Proven hands-on troubleshooting skills at both the control loop and power conversion system levels.

Solid understanding of advanced power electronics topologies.

Experience with pulse width modulation (PWM) techniques, including sinusoidal PWM and space vector PWM.

Experience with power conditioning techniques, including nonlinear, unbalanced, and harmonic compensation.

Proficient in power electronics modeling and simulation tools such as LTspice, MATLAB, Simulink, and PSIM.

Familiarity with DSPs (Digital Signal Processors), especially TI DSPs.

Experience developing control systems for MCUs and DSPs in C programming.

Knowledge of communication protocols such as SPI, CAN, I2C, and Modbus TCP/IP.

Experience using software management systems and version control tools (e.g., GitHub or GitLab).

Familiarity with test equipment such as oscilloscopes, digital multimeters, power analyzers, and spectrum analyzers.

Familiarity with low-voltage distribution systems: single-phase, split-phase, and three-phase systems up to 600VAC and frequencies ranging from 50 to 800 Hz.

Basic understanding of PCB design tools such as Altium, PADS, EAGLE, or KiCAD.

Excellent oral and written communication skills with the ability to collaborate effectively across disciplines.

Ability to take personal responsibility for complex design and development tasks, seeing projects through to completion.

Required:

Documented US citizenship or legal permanent resident status.

Physical Requirements:

Must be able to perform tasks such as climbing stairs, sitting, standing, keyboarding, seeing, hearing, and fluently reading and speaking English.
