Electrical Engineer 5 - Power Electronics

Job Title: Electrical Engineer 5 - Power Electronics
Duration: 2+ Years
Important: Do not submit candidates without power electronics experience.
Position Overview:
We are seeking a highly motivated Electrical Engineer 5 with a strong background in power electronics to join a leading engineering team in Mossville, IL. This long-term, onsite opportunity offers the chance to work on cutting-edge technologies involving inverter and converter systems across multiple vehicle platforms. Candidates must have a passion for hands-on work in test validation, prototyping, and system optimization.
Key Responsibilities:

• Lead the development of test plans, validation procedures, and technical documentation to ensure compliance with functional and performance specifications.
• Design, model, and simulate power electronics systems, including AC-DC and DC-DC converters and inverters.
• Build, test, debug, and optimize hardware prototypes for power electronics systems.
• Collaborate cross-functionally with electrical, mechanical, PCB layout, and firmware engineers during the design and validation process.
• Conduct root cause analysis using lab equipment such as oscilloscopes, power analyzers, and thermal cameras.
• Perform system validation under various environmental and operating conditions (e.g., voltage, temperature, load, EMI/EMC).
• Work closely with suppliers and internal teams on DFT (Design for Testability) and DFM (Design for Manufacturing) best practices.
• Ensure adherence to rigorous safety standards during high-voltage testing.

Required Qualifications:

• Master's degree in Electrical Engineering, Power Electronics, or a related field.
• Minimum 2 years of hands-on experience in power electronics testing and validation.
• Proficient with converter/inverter prototyping, debugging, and test bench operation.
• Solid understanding of DC-DC converters, AC-DC inverters, magnetics, and control algorithms.
• Skilled in the use of lab instruments and data acquisition systems.
• Experience with simulation tools (MATLAB/Simulink, PLECS, LTspice).
• Familiarity with relevant standards (UL, IEC, ISO) for power electronics systems.

Preferred Qualifications:

• Experience with automated test systems and scripting.
• Knowledge of EMI/EMC testing, thermal management, and environmental validation.
• Understanding of embedded systems and microcontroller-based control strategies.

Team & Project Environment:

• Work within a collaborative and innovative R&D group focused on advancing electrified vehicle technology.
• Direct impact on next-generation power electronics systems that support efficiency, sustainability, and performance.
• Opportunity to engage in meaningful technical work with real-world product applications.
