Résumé du poste

Endurance Energy in Seattle seeks a Senior/Principal Power Electronics Engineer to architect and own electrical power systems for subsea generation, conditioning, and shore delivery. You’ll design architectures, develop PCBAs, and drive from concept to offshore deployment, ensuring robust performance in harsh environments.

You will blend theory with hands‑on hardware delivery, selecting topologies, laying out high‑power boards, debugging noise, and guiding designs through production, with

Qualifications

• 6+ years of experience designing and shipping power electronics hardware in demanding or high‑reliability environments.
• Demonstrated experience architecting complete power systems, not just individual boards or subcircuits.
• Deep understanding of power conversion fundamentals including topology tradeoffs, control loop stability, magnetics design, switching losses, thermal modeling, and efficiency optimization.

Responsabilités

• Architect and design subsea power conversion and distribution systems from generator interface through export and load integration.
• 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 focus on high di/dt loops, parasitic inductance, creepage and clearance, EMI containment, and thermal paths.
• 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.
• 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
