Job summary

Stormentum is seeking a Principal Power Electronics Engineer to own the hardware design of the power conversion stage, spanning DC‑DC battery interface and DC‑AC grid interface, from topology selection through high‑volume production.

You will lead schematic decisions, drive PCB layout, and qualify wide‑bandgap devices, collaborating with controls and firmware to meet performance and certification requirements.

Qualifications

• MS in Electrical Engineering or related field; PhD a plus.
• 10+ years of end‑to‑end power electronics product development experience.
• Hands‑on with wide‑bandgap devices (SiC, GaN) and schematic/PCB design.
• Experience with circuit modeling, simulation, and PCB design tools (SPICE, MATLAB/Simulink, PLECS, Altium).
• Lab experience with oscilloscopes, power analyzers, electronic loads, grid simulators.
• Knowledge of grid‑interconnection standards (UL 1741 SA/SB, IEEE 1547, UL 1741 PCS, UL 1998, IEC 61508).

Responsibilities

• Lead design and development of the power conversion stage for the modular multilevel converter platform.
• Own schematic capture for high‑power, high‑voltage converter hardware and provide direction on PCB layout.
• Select and qualify power semiconductor devices (SiC, GaN, IGBT) and drive trade‑offs across efficiency, thermal performance, and cost.
• Design and validate power topologies for DC‑DC and DC‑AC stages including MMC, 3L, multilevel, or SST architectures.
• Lead EMI/EMC design and compliance activities for grid‑connected hardware.
• Own hardware development from concept through high‑volume production, including DFM and DFA.
• Lead lab bring‑up, testing, and debugging of prototype and production hardware.
• Set technical direction for power electronics design decisions and mentor the hardware team.
• Collaborate with controls, firmware, and systems architecture to align with performance and certification requirements.
