BESS Engineering Director, Global

About the role

Enfinity Global is seeking an experienced BESS Engineering Director to lead the engineering and technical function for battery energy storage systems across its global storage pipeline. The role owns the technical and engineering definition of BESS assets end to end, from system architecture and technology selection through design, integration and engineering oversight during construction and commissioning. It is an engineering leadership position, not a commercial or business development role.

Key responsibilities

• Define the engineering and system architecture for BESS assets and select technologies (cells, PCS, EMS, BoP) suited to the portfolio across geographies and regulatory frameworks.
• Establish design standards and engineering criteria for grid services, merchant storage, hybrid solar-storage and utility-scale deployments.
• Develop technical specifications, engineering requirements and design documentation to guide procurement, EPC scope definition and project execution.
• Support Procurement on vendor selection and mid- to long-term technical strategy, defining technical requirements and ensuring solutions meet engineering, performance and sustainability needs.
• Engage major BESS vendors (Fluence, Wartsila, Sungrow, Tesla, Jinko, CATL, E-Storage) to assess their technical capabilities, design maturity, performance and engineering differentiation.
• Lead technical and engineering due diligence during procurement, including design review, performance modelling, warranty terms, degradation and long-term reliability metrics, and advise on supplier quality and geopolitical risk mitigation.
• Provide engineering oversight during construction of hybrid and stand-alone projects, coordinate with EPC contractors and engineers, conduct inspections and quality assurance reviews, and maintain documentation for commissioning readiness.
• Act as the engineering authority and technical reference point for BESS within the Storage Global team, define the engineering and technology roadmap, and represent Enfinity externally in supplier discussions and sector forums.

Required profile

• Bachelor's or master's degree in electrical engineering, Renewable Energy Systems or a related technical discipline.
• 10+ years of experience, with at least 5 years in BESS engineering and system design, ideally at a manufacturer, integrator or EPC level.
• Experience supporting procurement with engineering input, vendor technical qualification and design-based evaluation.
• Familiarity with the business models driving BESS adoption in the U.S., EU and Asia markets.
• Excellent communication skills in a cross-functional, multicultural environment.

Required skills

• Deep knowledge of cell technologies, PCS and EMS architectures, balance of plant and full system integration and design.
• Vendor ecosystem and procurement structures, and price benchmarking.
