Are you passionate about clean energy and ready to make a real impact? We're looking for an energetic and forward-thinking Director, Commercial & Industrial Product Line Manager to join our team. In this pivotal role, you'll guide our C&I Energy Storage Systems (ESS) portfolio, turning ideas into products that power small businesses, fleet depots, microgrids, data centers, and utility-connected systems. You'll be at the heart of innovation—driving development, launch, and ongoing improvement of our solutions to meet and exceed market needs.

• Develop and lead the strategic roadmap for EG4’s C&I ESS product lines.
• Position our products for key markets including fleet charging, microgrids, peak shaving, municipal/co‐op VPPs, commercial backup, and edge data center applications.
• Translate market and customer needs into product requirements—covering electrical, mechanical, thermal, battery management, and energy management system specifications from concept through launch.
• Define technical requirements for battery packs, BMS, HVAC/chiller integration, inverter specs, wiring, safety logic, and installation processes.
• Oversee integration of cutting‑edge technologies and key system components in line with industry standards.
• Approve critical design elements such as schematics, wiring diagrams, 3D CAD models, busbars, cooling systems, and service layouts.
• Lead UL certification efforts, including sample production, lab scheduling, and corrective actions.
• Manage prototype builds, validation testing, functional safety, and fault testing (DFMEA).
• Collaborate closely with vendors and manufacturing partners to ensure smooth product development and launch.
• Oversee product launches at major industry events, including documentation, installer training, and technical support.
• Own the product lifecycle, driving change management (ECNs/ECRs), cost reduction, reliability, and ongoing firmware/hardware improvements.

• You have hands‑on expertise with three‑phase power, grid‑interactive systems, fault current dynamics, and protective schemes.
• You bring a strong background in ESS: battery management (BMS), BPUs, HV Boxes, Container Solutions, Hybrid inverters, thermal systems, HVAC/chillers, and cabinet design.
• You understand UL testing and NFPA standards.
• You’re skilled in reading and creating electrical schematics, wiring diagrams, mechanical layouts, and thermal designs.
• You have experience with communication protocols like Modbus TCP, Sunspec, EMS/VPP controls, CAN, and API vendor integrations.
• You’re comfortable collaborating with international vendors and partners.

• Experience with high‑voltage industrial battery packs.
• Background in HVAC/chiller engineering (heating, cooling, glycol systems).
• Familiarity with regulatory documentation and domestic content strategies.
• Direct commissioning experience with C&I ESS, microgrid systems, or hybrid inverters.

• This position may require the ability to perform tasks that involve sitting, standing, walking, lifting 25+ lbs, computer work and other physical activities. Candidates should be able to meet these physical demands with or without reasonable accommodations.
