• 7+ years of hands‑on experience designing and testing power electronic subsystems.
• Specific experience in the design and testing of power electronics for electrical power generation.

Technical Skills – Required

• Demonstrated capability to design and test IGBT‑based 30 kW–500 kW power inverters.
• Demonstrated capability to design and test high‑voltage DC/ DC converters.
• Knowledge and experience designing noise‑immune power and control circuits, including EMI filter design and troubleshooting.
• Proficiency with power electronics simulation tools: PSIM Pro, MATLAB/Simulink, and PSPICE.
• Excellent background in the design of magnetic devices including generators, inductors, and transformers.
• Demonstrated capability in schematic design and PCB layout.
• Knowledge and experience with electronic component selection.
• Demonstrated interpersonal skills to collaborate within multidisciplinary design and production teams.
• Demonstrated leadership and communication skills; ability to supervise junior engineers.

Technical Skills – Preferred

• Knowledge and experience developing Battery Management Systems for Lithium, Lead/Acid, and other battery chemistries.
• Familiarity with low‑power supply design.
• Familiarity with Ansoft Finite Element Analysis tools.
• Real‑time programming and debugging in C and assembly language.
• Capability to understand mechanical engineering, physical, thermodynamic, and chemical principles relevant to power system design.
• Experience with OrCAD and PADS for schematic capture and PCB layout.
• Familiarity with high‑speed digital circuit design using microprocessors and DSPs (Microchip, TI, Motorola).
• Experience with HALT and HASS testing methodologies.
• Familiarity with motor drives and power supply design and test environments.

What Success Looks Like

• Power electronics subsystems delivered on schedule that meet or exceed performance specifications.
• Thorough, well‑documented requirements and design records that support product quality and compliance.
• Reliable, efficiently designed magnetic components, inverters, and converters integrated across Capstone platforms.
• Cross‑functional collaboration that accelerates development cycles and reduces rework.
• A test and validation culture that catches issues early and drives continuous product improvement.

Work Environment
