BESS Engineering Lead

Intersect is a company focused on innovative energy solutions and modern infrastructure, recently acquired by Google to enhance energy development. The BESS Engineering Lead will oversee the technical design and optimization of energy storage systems, collaborating across various teams to ensure project success.

Responsibilities:

• Lead system sizing, arrangement, electrical modeling, and balance-of-system design for standalone and hybrid ESS projects
• Ensure storage systems meet contractual offtake requirements and financial model assumptions over the life of the asset
• Optimize designs to achieve lowest LCOE/LCOS while maintaining constructability and reliability
• Guide cross-functional design efforts across Development, Land, Finance, and Engineering to align cost, production, land use, and performance
• Identify technical risks and opportunities early, quantifying impacts and mitigation strategies
• Support Procurement and Operations teams with technical expertise throughout project lifecycle
• Serve as technical lead in energy storage PPA negotiations, delivering cost-optimized and constructable solutions
• Support EPC RFP processes and commercial supply agreements by clearly defining and safeguarding technical requirements
• Act as ESS technical lead for Independent Engineer diligence and project financing processes
• Lead equipment and technology selection, evaluating lithium-ion and alternative storage technologies for bankability and performance
• Develop and maintain technical specifications, design standards, EPC exhibits, vendor requirements, and testing protocols
• Build and enhance internal engineering tools or software (VBA, Matlab, Python, or similar) to generate fast, accurate performance modeling
• Interface with ESS integrators, vendors, EPCs, and Owners Engineers to ensure technical alignment
• Uphold the highest environmental health and safety standards across all engineering decisions

Requirements:

• BS in Electrical Engineering or equivalent; Master's or PhD is a plus
• Minimum 4 years of experience leading technical scope for utility-scale PV and/or battery storage projects across development, design, contracting, and construction phases
• Deep technical expertise in lithium-ion battery systems, including chemistries, system architecture, optimization levers, cost drivers, lifecycle considerations, and construction challenges
• Strong understanding of utility-scale power conversion systems, transformers, skidded inverters, and battery technologies; PV engineering experience is a plus
• Working knowledge of applicable codes and standards (NEC, IBC, IFC, NFPA, UL, IEC, UL9540A, UL1741, etc.) across permitting, design, construction, and operations
• Experience supporting Independent Engineer diligence and interfacing with project finance stakeholders
• Familiarity with alternative storage technologies (flow batteries, hydrogen, flywheels, compressed air, etc.) is a plus
• Proficiency in scripting or automation tools such as VBA, Matlab, Python, or similar
• Background in power plant controls architecture and SCADA is a plus
• Commercial mindset with strong focus on LCOE/LCOS optimization and risk quantification
• Ability to thrive in a cross-functional environment, guiding discussions across engineering, land, production modeling, cost, and development dependencies
• Strong project management skills with the ability to prioritize effectively in a fast-paced growth environment
• Collaborative, solutions-oriented approach aligned with Intersect's mission and growth mindset
