Position Overview

We are hiring a Battery Application Engineer for our new Battery Application Engineering team in Westborough, MA. This engineer will be a key technical resource for LGES Vertech's AC- and DC-coupled BESS products.

This is a product-focused technical role. For AC products, the engineer defines AC-LINK (Battery + Inverter) Grid Code requirements and turns them into product specifications. For DC products, the engineer supports the US team on LGES HQ battery products. In both areas, the engineer gives Sales and Project Engineering clear, practical technical guidance.

Key Responsibilities

• Serve as the internal technical resource for assigned BESS product lines -- answering inquiries, supporting proposals, and clarifying product specifications for Sales Engineering and Project & System Engineering teams.
• Analyze applicable technical requirements (Grid Code, customer specs, US standards) and translate them into product-level requirements; identify gaps between current product capabilities and market needs.
• Build and maintain standardized product documentation: Technical Datasheets, System Architecture Overviews, Interface Definitions, Compliance Summaries, and Q&A packages.
• Define what the Battery + Inverter product must satisfy at its AC output boundary in terms of Grid Code performance (LVRT/HVRT, Frequency Response, GFM/GFL, Power Quality); communicate these as product requirements to internal engineering teams.
• Support pre-award and post-award activities: proposal reviews, technical clarifications, design deviation tracking, and customer technical queries.
• Contribute to team knowledge base with lessons learned, templates, and case studies.
• Coordinate with ESVT Sales Engineering, Project & System Engineering, and HQ technical teams on active proposals and projects.

Required Qualifications:

• Bachelor’s degree in electrical engineering, Power Systems, Electrochemistry, Mechanical Engineering, Structural Engineering, Civil Engineering, Energy Engineering, or related field.
• 5+ years of experience in battery energy storage, power electronics, inverter/PCS systems, mechanical/structural engineering for large-scale equipment, or a closely related field.
• Technical depth in at least one of the following, with general familiarity in the other:
• AC power systems and grid-tied inverter/PCS technology; understanding of Grid Code requirements (LVRT/HVRT, Frequency Response, GFM/GFL) as they apply to inverter-based BESS products.
• Ability to read and interpret technical documents including engineering drawings, single-line diagrams, and product specifications.
• Strong written and verbal communication skills in English; Korean proficiency is a plus.
• Proficiency in Microsoft Office; SharePoint experience is a plus.
• Experience in utility-scale or C&I energy storage projects preferred.
• Experience working in engineering, sales, and project management teams is preferred.

No Agency Solicitation: This role is being managed directly by our internal Talent Acquisition team. Please no unsolicited outreach, resumes, or candidate submissions from third-party agencies.
