The rapid rise of AI and hyperscale data centers is exposing a fundamental limitation in the world's electrical infrastructure: the grid was never designed to support the scale, density, and dynamic power demands of modern computing. As demand accelerates beyond the capabilities of aging infrastructure, the industry's greatest challenge is no longer simply generating more electricity. It's fundamentally rethinking how power is converted, distributed, stored, and intelligently managed, from the grid to the GPU. Stormentum is pioneering a new generation of intelligent power infrastructure for AI data centers, microgrids, EV charging, and the broader energy ecosystem. Our proprietary controls platform and Modular Power Electronics Converter architecture eliminate unnecessary complexity, reducing power conversion from as many as seven stages to just three across legacy 480 VAC and native 800 VDC architectures. By replacing traditional monolithic systems with coordinated, software-defined modular power cells, Stormentum unifies power conversion, energy storage integration, and intelligent control into a highly scalable platform spanning kilowatts to megawatts. Founded by executives who have built and scaled category-defining companies across the semiconductor, wireless, and energy industries, Stormentum is bringing together world-class engineering talent to redefine how electrical power is delivered, controlled, and utilized. We're not simply improving existing power infrastructure. We're reinventing it from the edge inward. Today we're an early-stage team building our platform from the ground up. If this is the kind of work that excites you, take a look at our open roles. We'd love to hear from you. About the Role At Stormentum you will join a team of engineers developing a distributed, modular power electronics conversion platform, built for data centers and microgrids. As Staff Systems Design Architect, you will operate at the system level, translating product requirements into actionable engineering specifications, defining how subsystems interact, and guiding hardware and firmware teams on the best way to build it. You will own the architecture that ties the platform together: how the distributed power cells interface with each other and with energy storage, data center loads, and the electrical grid, taking it from design through integration, certification, and production. Who You Are A systems thinker. You see the full picture before the details. You are as comfortable defining how subsystems interact as you are diving into the tradeoffs within them. An owner. You have taken systems from concept to production and you know what it takes to get there. You do not hand off and walk away, you see it through. A builder. You thrive in environments where the architecture does not yet exist. You are energized by defining it from scratch and guiding a team to execute against it. A cross-functional partner. You have led design reviews, risk assessments, and cross-functional teams across hardware, firmware, controls, and mechanical disciplines. You earn trust through technical depth and clear communication. Grid-fluent. You understand how power electronics systems interact with the grid, energy storage, and the loads they serve, from data centers to microgrids, and you bring that knowledge to every architectural decision. What You'll Do Define and decompose system-level requirements into hardware, firmware, controls, and integration specifications Develop and maintain system block diagrams and interface control documents Define system-level performance and safety test requirements and support the development of automated test equipment to accelerate testing Own and report on architectural trade-offs across high voltage, low voltage, mechanical, and communications domains Lead engineering teams through the Hazard and Risk Assessment and support the DFMEA, PFMEA, and safety test processes Design the system integration architecture connecting Stormentum's platform with energy storage, generators, data center and microgrid loads, and the electrical grid Run system-level simulations to evaluate design options and guide engineering decisions Lead the product through 3rd-party integrations and support certification including UL and applicable grid codes Serve as the primary technical liaison between product and engineering, translating customer, installer, utility, and regulatory requirements into engineering direction Lead system-level design reviews and risk assessments across subsystems Manage the handoff from design through manufacturing ensuring designs are optimized for production Collaborate cross-functionally with mechanical, firmware, controls, and hardware teams across the full product lifecycle What You'll Bring Master's degree in Electrical Engineering or Physics 5+ years of experience in electrical systems design, including at least one full product cycle taking distinct products from concept to production Deep experience integrating power electronics systems with external interfaces, such as the grid, energy storage, servers, microgrids, or distributed energy resources Experience with high-voltage power conversion systems at 400 V and above, such as grid-tied inverters, energy storage, EV charging, or industrial power equipment Deep experience building system-level electrical physics models in MATLAB/Simulink or similar tools, and analyzing topologies and component parameters to find optimal solutions to product-level requirements Breadth across high voltage, low voltage, mechanical, thermal, and communications domains Experience with processes similar to those outlined in

What Will Make You Stand Out Experience collaborating or leading Hazard and Risk Assessments and DFMEA Experience with data center power hardware, such as 480V AC three phase and 800 VDC rack power systems or power shelves, or with modular multilevel converter architectures Experience with grid-tied inverter systems Knowledge of grid-forming inverter technologies and advanced grid-support functions Experience maintaining requirements within tools such as DOORS, Jama, or Polarion Familiarity with
