About the Job :

We're looking for a Power Electronics Lead to join our Energy Storage Systems (ESS) Engineering team. This person will be responsible for the architecture, design, and technical direction of our power conversion systems. You'll play a critical role in shaping how energy moves within and beyond our battery systems—from cell to grid.

We're seeking someone with deep technical experience and a track record of shipping high-reliability, high-voltage power systems. This role is ideal for a hands-on engineer who wants to own hard problems, work cross-functionally, and help build world-class energy storage products from the ground up.

Responsibilities :

• Lead the design and development of high-voltage power conversion systems within Peak's energy storage platform—including DC / AC inverters, bidirectional DC / DC converters and protection circuitry.
• Define and maintain system-level electrical requirements for power stages, gate drives, control loops, safety interfaces, and EMI / EMC performance.
• Select and integrate key components (e.g., IGBTs, SiC / GaN FETs, magnetics, busbars, filters) and collaborate closely with mechanical and thermal engineers to support packaging and cooling.
• Own system-level testing and validation—both in-lab and in-field—including HV safety, transient behavior, thermal performance, and fault response.
• Interface with firmware, controls, and systems teams to ensure robust hardware / software integration and safe system operation.
• Support regulatory certification and compliance activities (e.g., IEEE 2800, UL 1741, IEEE 1547, IEC 62109).
• Act as a technical leader and mentor across the ESS team—setting high standards, reviewing designs, and driving toward first-principles, scalable solutions.
