Job description

We are seeking a powerhouse Technical Product Lead to drive BESS product lines from initial architecture to global certification and high-volume production.

This is a hands-on technical leadership role requiring deep energy storage expertise and strong execution discipline

Key Responsibilities

• Product Architecture & Design: Define standard BESS system architecture and roadmaps. Balance performance, safety, DFM/DfR, cost, and strict thermal constraints.
• Validation & UL Certification: Own the end-to-end product validation strategy. Lead UL certification efforts (UL 1973, 9540, 9540A, NFPA 855) to prevent late-stage redesigns.
• Contract Manufacturer (CM) Oversight: Lead the technical relationship with CMs. Supervise tooling, process design, quality KPIs, production ramp-up, and root-cause troubleshooting.
• Value Engineering & Cost Discipline: Drive cost-versus-performance trade studies early. Eliminate overdesign and partner with the supply chain to hit target costs without compromising safety.
• Cross-Functional Leadership: Enforce configuration control and Engineering Change Notices (ECN). Collaborate with Controls, R&D, and Sales to ensure clean field integration. Manage and mentor the engineering team.
