About the role

This position leads product management for Enphase's Solid-State Transformer (SST) platform — a new category of grid-scale power conversion product built around a modular, GaN-based power architecture that scales from a single power module to multi-MW skids for AI data center and other high-density grid-connected applications. This role owns the product strategy, business case, and customer/market engagement for SST as it moves from architecture definition through certification and initial deployment, working in close partnership with engineering, program management, and executive leadership to define what Enphase builds and why.

What you will do

• Own the SST product strategy and roadmap, translating market and customer requirements into a coherent product definition across power, control, communications, and serviceability.
• Lead voice of customer and partner efforts, initially focusing on hyperscaler/datacenter RFQ processes and strategic partnerships (e.g., channel and technology partnerships with established power equipment providers). Then, eventually branching into other applications of SST, including DC fast charging, solar, battery energy storage, and other utility-oriented applications.
• Use the voice of customer information to synthesize requirements, and work with the sales and marketing leaders to define pricing and go-to-market positioning.
• Define and prioritize product requirements for the modular power module and skid-level system, balancing power density, cost, manufacturability, serviceability, and certification constraints.
• Partner with engineering leadership to align product requirements with system architecture decisions (e.g., grid-forming/grid-following control strategy, MV interconnection approach, module interchangeability across skid configurations).
• Own the business case for SST products, including build-cost tracking, margin targets, and total-cost-of-ownership positioning against alternative power conversion architectures.
• Drive the certification and standards roadmap in partnership with compliance and systems engineering — maintaining product-level line of sight into UL 347A, UL 2877, IEC 62477-2, UL 1741, and relevant IEEE standards and requirements and their impact on product scope and timeline.
• Build and manage the SST product launch plan across DVT, factory test, field trials, and general availability, coordinating cross-functionally with program management, manufacturing, and quality.
• Manage and mentor a small team of product managers as the SST product line scales; contribute to hiring and org design decisions.
• Report on product strategy, business case, and program status to executive leadership.

Who you are and what you bring

• B.S./M.S. in Electrical Engineering, Computer Engineering, or a related technical field; formal business training, such as an MBA, is a plus.
• 12+ years in product management or related technical product/business experience, with a track record of shipping complex hardware or hardware/software systems from concept to volume production.
• Direct experience with power electronics, power conversion, energy storage, or grid-connected equipment; comfortable engaging technically with power topology, control architecture, and interconnection standards discussions.
• Experience selling into or partnering with data center, utility, or large industrial/commercial customers; RFQ and enterprise sales-cycle experience strongly preferred.
• Working familiarity with relevant standards and certification bodies (UL, IEC, IEEE) as they shape product requirements and timelines, and the judgment to know when to pull in compliance and systems engineering expertise.
• Strong business acumen — particularly with TCO and defending a business case to executive leadership.
• Demonstrated ability to participate in cross-functional teams and drive alignment among engineering, program management, manufacturing, and customers without relying solely on formal authority.
• Excellent written and verbal communication skills, with experience presenting strategy and status to senior executives.
• Experience with modular or platform-based hardware product strategy (reference architectures, product families, reuse across generations) is a strong plus.
• Experience with channel or technology partnerships (e.g., co-development or distribution agreements with established equipment manufacturers) is a plus.
• Experience with formal product requirements processes, such as JAMA or others, is a plus.
