Electrical Design Engineer - Power Conversion
role at
Caterpillar Inc.
Job Summary The Electrification and Energy System Division is looking for an engineer to support the development of Caterpillar Advanced Power conversion systems. In this role, you will design and develop power conversion systems for Caterpillar advanced power products. Specific products include off board DC chargers, automated and manual connection systems, bi‑directional inverters, and related controls/operational interfaces. This role will collaborate with cooling, battery, power conversion, and controls teams along with purchasing and validation teams. In addition to technical collaboration this engineer will be responsible for the design and performance quality of charging systems from development through production.
What You Will Do
Develop test plans, validation procedures, and documentation to ensure functional and performance compliance, taking full ownership of the assigned task.
Design, model, and simulate power electronics systems.
Design prototype, debug, and fault‑analyze power electronic hardware (inverters/converters) and optimize.
Collaborate with design engineers to ensure smooth transition from design to validation and production.
Collaborate with mechanical, PCB layout, and firmware engineers to develop and validate design.
Utilize laboratory equipment (oscilloscopes, power analyzers, thermal cameras, etc.) to conduct detailed analysis and root‑cause investigations.
Perform design validation under various operating conditions (temperature, voltage, load profile, EMI/EMC).
Interface with suppliers and internal manufacturing teams for design for testability (DFT) and design for manufacturing (DFM).
Maintain rigorous safety protocols during high‑voltage testing activities.
What You Will Have
Analytical Thinking: Extensive experience and knowledge of techniques and tools that promote effective analysis; ability to determine the root cause of organizational problems and create alternative solutions that resolve these problems.
Effective Communications: Working knowledge and understanding of effective communication concepts, tools and techniques; ability to effectively transmit, receive, and accurately interpret ideas, information, and needs through the application of appropriate communication behaviors.
Managing Multiple Priorities: Working knowledge of effective self‑management practices; ability to manage multiple concurrent objectives, projects, groups, or activities, making effective judgments as to prioritizing and time allocation.
Technical Excellence: Working knowledge of a given technology and various application methods; ability to develop and provide solutions to significant technical challenges.
Hands‑on experience with converter/inverter prototyping, test benches, and debugging.
Strong understanding of DC‑DC converters, AC‑DC inverters, magnetics, and control algorithms.
Proficiency in using lab instruments and data acquisition tools.
Familiarity with simulation tools such as MATLAB/Simulink, PLECS, or LTspice.
Experience with standards and compliance (UL, IEC, ISO) for power electronics systems.
Computer‑Aided Design & Engineering: Extensive experience and knowledge of tools and techniques of specialized graphics programs; ability to produce, analyze, simulate and test product design drafts.
Product Design - MFG: Extensive experience and knowledge of processes, approaches, tools, and techniques of product design; ability to convert customer and market requirements into product design.
Product Testing: Working knowledge of product testing approaches, techniques, and tools; ability to design, plan and execute testing strategies and tactics to ensure product quality at all stages of manufacturing.
Degree Requirement
Associate’s degree in Electrical Engineering
Top Candidates Will Also Have
Bachelor’s or Master’s degree in Electrical Engineering
Experience with automated test systems.
Understanding of EMI/EMC testing, thermal design, and environmental validation.
Knowledge of embedded systems and microcontroller‑based converter control.
Location This position is located in Mossville, IL and requires 5 day a week in office availability. Travel is expected less than 20% of the time. Domestic relocation is offered. Visa sponsorship is not available.
Benefits Medical, dental, and vision benefits; Paid time off plan; 401(k) savings plans; Health Savings Account; Flexible Spending Accounts; Health Lifestyle Programs; Employee Assistance Program; Voluntary Benefits and Employee Discounts; Career Development; Incentive bonus; Disability benefits; Life Insurance; Parental leave; Adoption benefits; Tuition Reimbursement.
