Power Electronics Design Engineer

Mesta Electronics, Inc. is a leading manufacturer based in the United States, specializing in the design, development, and manufacture of advanced power quality and power conversion equipment. As part of the global Hammond Power Solutions network, Mesta Electronics, Inc. is committed to innovative design, superior efficiency, and exceptional reliability, ranging from highly advanced harmonic filters to extremely precise induction heating power supplies. Our expertise in designing dry-type transformers and related technologies has positioned us as an industry leader for over a century.

Reporting to the Operations Manager, the Power Electronics Design Engineer is responsible for supporting the design, development, validation, and test of power-conversion hardware used in industrial, energy, and power-quality applications. This role focuses on translating system-level requirements into detailed power-electronics designs, including power stages, magnetics, protection circuits, mechanical design, and supporting control interfaces. This role collaborates closely with systems, firmware, mechanical, manufacturing, and quality teams to deliver innovative power conversion products.

Key Responsibilities include:

• Design & Development
• Support the design and analysis of 3-phase inverters & other power electronics solutions such as rectifiers, DC-DC converters, active harmonic filters, induction heating supplies, or grid-connected converters.
• Support component selection for power semiconductors, magnetics, capacitors, resistors, and protection devices.
• Perform basic electrical calculations (losses, efficiency, thermal margins) and support advanced analysis including thermal modeling, derating, and efficiency optimization.
• Support the design and analysis of 3-phase inverters & other power electronics solutions such as rectifiers, DC-DC converters, active harmonic filters, induction heating supplies, or grid-connected converters.
• Support component selection for power semiconductors, magnetics, capacitors, resistors, and protection devices.
• Prototype Build & Testing
• Assist with prototype assembly, bring-up, and debugging in the laboratory and coordinate 3rd party testing if/as required
• Define and execute test procedures for functional, thermal, EMI/EMC, and performance validation.
• Collect, document, and summarize test data for product development project reporting.
• Interpret test results, identify root causes, and support implementation of corrective design changes.
• Assist with regulatory and standards compliance (UL, IEC, IEEE, CE, EMC, safety, seismic where applicable).

• Manufacturing & Documentation Support
• Assist with BOM creation, part substitutions, and engineering change documentation.
• Drive completion and implementation of sustaining engineering initiatives including Engineering Change Orders (ECOs).
• Maintain engineering documentation including schematics, test reports, and revision histories.
• Support transition from prototype to production, including BOM optimization and supplier coordination.
• Provide technical support to manufacturing and quality teams for released products.
• Support Design for Manufacturability (DFM) and Design for Assembly (DFA) activities.
• Produce documentation needed by manufacturing to build new or modified products.
• Cross Functional Collaboration
• Participate in cross-functional design reviews, project meetings, and formal product development processes.
• Work closely with firmware, mechanical, manufacturing, and applications engineers.
• Actively learn company design standards, safety practices, and regulatory requirements.
• Seek feedback and mentoring to build technical depth and engineering judgment.
• Other duties as defined by management

Do you qualify? We are seeking:

• BSEE required, MSEE preferred or equivalent experience in Engineering or a related field
• 2-5 years of experience in engineering role within a manufacturing environment.
• Fundamental understanding of power-electronics concepts (rectification, switching, PWM basics).
• Familiarity with common power components (MOSFETs, IGBTs, diodes, magnetics, passives).
• Exposure to schematic capture and PCB design tools (training or academic use acceptable).
• Basic laboratory skills using oscilloscopes, multimeters, power supplies, and electronic loads.
• Introductory experience with simulation tools (SPICE-based or MATLAB preferred).
• Experience working with embedded control interfaces and collaborating with firmware teams.
• Strong analytical, problem-solving, and troubleshooting skills.
• Ability to work effectively in a team-based, structured engineering environment.
• Effective written and verbal communication skills in a cross-functional engineering environment.
• Knowledge of power inverters, variable frequency drives, or other related industrial power conversion equipment
• Digital and analog circuit design and printed circuit board layout.
• Knowledge of transformers, inductors, and other electrical magnetic products
