Job Title: Sr. Power Electronics Engineer
Job Type: Direct Hire
Location: Sterling VA 
Work Aurthorization: US Citizen or Green Card 

Job Description: 
As a Senior Power Electronics Engineer, you will own the electrical design of high-current solid-state switching platforms that power mission-critical environments. Your work will directly influence the reliability, protection strategy, and performance of systems where failure is not an option. You will lead detailed schematic design for SCR/thyristor-based switching architectures, shaping protection strategies, fault response behavior, and thermal performance at the system level. This role blends deep technical expertise with cross-functional leadership, partnering with firmware, mechanical, manufacturing, and compliance teams to bring robust, UL-certified power platforms to market.

Your Day-to-Day Responsibilities

• Contributing to system-level architecture and electrical subsystem definition for high-current solid-state switching equipment
• Owning detailed power and control schematic design for SCR/thyristor-based switching platforms
• Designing and optimizing critical circuits including:
• Isolated gate drive and firing circuits
• Snubber networks and dv/dt protection
• di/dt limiting strategies
• Fault commutation and semiconductor protection mechanisms
• Performing thermal analysis and Safe Operating Area (SOA) evaluations for high-power semiconductor modules
• Conducting short-circuit, overload, fault current, and protection coordination studies
• Reviewing PCB layouts for high-current routing, creepage/clearance compliance, isolation integrity, and EMC performance
• Supporting high-current validation and lab testing activities (up to 1600A)
• Participating in cross-functional design reviews and providing technical guidance to firmware, mechanical, and manufacturing teams
• Supporting compliance-driven development and UL certification efforts for low-voltage power electronics products

Qualifications

• Bachelor’s degree in Electrical Engineering (Master’s preferred)
• 7+ years of hands-on experience in industrial power electronics design
• Proven experience designing schematics for high-current systems
• Deep expertise in SCR/thyristor-based solid-state switching systems
• Experience developing industrial power electronics equipment such as inverters, converters, or static switching systems
• 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 in high-power applications
• Working knowledge of EMC/EMI mitigation techniques in power electronics

Preferred Qualifications

• Experience supporting products through UL certification or compliance testing
• Familiarity with simulation tools such as MATLAB/Simulink, PLECS, or LTspice
• Background in redundant or high-reliability power architectures
• Experience with FPGA/DSP-based control platforms for power switching applications

Core Competencies

• Safety: Proactively fosters a culture of safety in high-power development and testing environments
• Inclusion: Appreciates and respects individuals from diverse backgrounds, identities, and values
• Speed: Operates with urgency in mission-critical product development timelines
• Innovation: Continuously improves system robustness, protection strategies, and design efficiency
• Judgment: Exercises strong technical decision-making in high-risk, high-current design scenarios
• Accountability: Owns design integrity, validation outcomes, and product reliability
