Senior Power Electronics Engineer

Key Responsibilities

• Select and justify converter topologies for AC-DC, DC-DC, and DC-AC systems based on efficiency, fault tolerance, thermal constraints, and scalability
• Design high-power PCBAs including schematic capture, magnetics design, gate drive architecture, current sensing, isolation strategy, and protection circuitry
• Own PCB layout review with specific attention to high di/dt loops, parasitic inductance, creepage and clearance, EMI containment, and thermal paths
• Mechanically collaborate on packaging, heat rejection, pressure-tolerant enclosures, and high-voltage isolation within subsea assemblies
• Define and implement system-level protection philosophy including overcurrent, overvoltage, short-circuit, ground fault detection, isolation monitoring, and coordinated fault response
• Develop fault trees and failure containment strategies to prevent single-point electrical failures from propagating through the system
• Lead board bring-up, lab validation, and full-load testing including efficiency characterization, thermal validation, EMI testing, and fault injection
• Drive root cause investigations for converter instability, switching noise, insulation breakdown, component overstress, and field failures
• Own the full system lifecycle including fabrication release, vendor coordination, revision control, and production readiness
• Integrate power hardware cleanly with controls, firmware, mechanical systems, and offshore operations
• Establish electrical design standards, review rigor, documentation discipline, and reliability practices appropriate for subsea energy infrastructure

Qualifications

• 6+ years of experience designing and shipping power electronics hardware in demanding or high-reliability environments
• Deep understanding of power conversion fundamentals including topology tradeoffs, control loop stability, magnetics design, switching losses, thermal modeling, and efficiency optimization
• Proven experience designing high-power PCBAs including schematic capture, layout collaboration or ownership, isolation strategy, and protection circuitry
• Strong working knowledge of grounding, shielding, EMI mitigation, creepage and clearance requirements, and high di/dt layout practices
• Experience implementing and validating protection strategies including overcurrent, overvoltage, short-circuit, ground fault detection, and fault isolation
• Hands-on lab experience bringing up high-power hardware, debugging instability, chasing down noise and parasitics, and performing controlled fault injection
• Experience with high-voltage systems or DC buses preferred, including practical understanding of insulation coordination and safety considerations
• Demonstrated ownership of hardware through full lifecycle including board release, fabrication, bring-up, revision control, and production transition
• High ownership mentality and comfort being the single-threaded owner of a critical electrical system
• Strong cross-disciplinary communication skills and ability to collaborate with mechanical, controls, subsea, and offshore operations teams
• Entrepreneurial mindset and willingness to operate in ambiguity while building a new class of energy infrastructure
