Senior Power Electronics Engineer - High-Current Switching

Gravity IT Resources; Sterling (VA); On-site; USD 120,000 - 180,000; Full time

Job summary

Gravity IT Resources seeks a Senior Power Electronics Engineer to lead electrical design for high-current solid-state switching platforms used in mission-critical environments.

You will own SCR/thyristor-based schematic designs and drive system protection, fault response, and thermal-management with firmware, mechanical, manufacturing, and testing teams to deliver reliable power systems.

Qualifications

• Bachelor's degree in Electrical Engineering or closely related discipline.
• 7+ years hands-on industrial power-electronics design experience.
• Demonstrated experience designing schematics for high-current electrical systems.
• Deep technical knowledge of SCR/thyristor-based solid-state switching systems.
• Experience developing industrial power-electronics equipment such as inverters, converters, static switches, or similar platforms.
• Familiarity with UL requirements and NEC guidelines for low-voltage power equipment.
• Proficiency with schematic-design tools such as Altium Designer or OrCAD.
• Experience reviewing PCB layouts for high-power applications.
• Working knowledge of EMC/EMI mitigation techniques within power-electronics systems.

Responsibilities

• Contribute to system-level architecture and electrical subsystem definition for high-current solid-state switching equipment.
• Own detailed power and control schematic design for SCR/thyristor-based switching platforms.
• Design and optimize critical circuits, including isolated gate-drive and firing circuits.
• Develop snubber networks and dv/dt protection.
• Implement fault commutation and semiconductor protection mechanisms.
• Perform thermal analysis and Safe Operating Area evaluations for high-power modules.
• Conduct short-circuit, overload, fault-current, and protection-coordination studies.
• Review PCB layouts for high-current routing, creepage/clearance, isolation, and EMC performance.
• Support high-current validation and laboratory testing up to 1600A.
• Lead cross-functional design reviews and guide firmware/mechanical/manufacturing/testing teams.
• Support compliance-driven product development and UL certification efforts.
