Job description

We are seeking an experienced and technically adept Product Manager to lead the product strategy and roadmap for our 3S [Power Conversion Systems (PCS), Battery Management Systems (BMS) & Energy Management Systems (EMS)] portfolio targeting the North America market. This role requires technical leadership, project execution experience as well as commercial considerations.

Responsibilities

• PCS & Grid Compatibility
• Define and own the PCS product roadmap for the North America market, aligning with regional regulatory standards (UL, IEEE, NEC, NERC, ANSI) and utility interconnection requirements (IEEE 1547, Rule21).Define system-level requirements for BESS applications including peak shaving, frequency regulation, black start, and capacity firming in collaboration with system integrators and EPCs.Engage with IRA, DOE incentive programs, and FEOC implications to shape product strategy that maximizes customer eligibility and commercial advantage.
• Conduct market analysis, competitive benchmarking, and customer discovery to identify product gaps and growth opportunities in utility-scale, commercial & industrial (C&I), and microgrid segments.Collaborate with R&D, hardware engineering, and firmware teams to translate customer requirements into detailed product specifications (power ratings, efficiency curves, grid-forming capabilities, protection schemes).Drive the full product lifecycle from concept through launch, including go-to-market planning, pricing strategy, and sales enablement.Manage product positioning against North American competitors
• EMSDefine EMS roadmap for C&I and utility grade applications for North America market.Define integration requirements for EMS-to-PCS communication protocols (Modbus, DNP3, IEC 61850, SunSpec, OCPP) and cloud platform APIs.Partner with the data and analytics team to build product features that enable customers to maximize ROI via automated dispatch, demand response, and wholesale market participation.Engage with system integrators, EPCs, and fleet operators to understand EMS usability, reporting, and remote monitoring needs.Grid Integration
• StrategyDevelop product strategies for grid-edge applications including virtual power plants (VPP), distributed energy resource management (DERM), and grid-forming inverter deployments.Track evolving interconnection standards, utility tariff structures, and capacity market rules (PJM, CAISO, MISO, ERCOT) to identify product development priorities.Collaborate with utilities, ISOs/RTOs, and grid operators to understand evolving grid service requirements and shape product capabilities accordingly.Support development of advanced grid services features: synthetic inertia, voltage/VAR support, droop control, and islanding/resynchronization functionality

Qualifications

• Bachelor’s degree or higher in Electrical Engineering, Power Electronics, Energy Systems or related field.5+ years of experience in energy storage, power systems, EV, or industrial equipment.Deep technical understanding of power conversion topologies (three-phase, bidirectional), grid interconnection requirements, and relevant North American standards (IEEE 1547, UL 1741, NEC Article705).Demonstrated experience managing product roadmaps and launching products in the utility-scale or C&I energy storage/solar-plus-storage market.Familiarity with BESS system architecture including BMS hierarchy, DC/AC coupling configurations, and safety certifications (UL 9540, NFPA855).
