Job Title:

Project Engineer - Thermal Management for Utility-Scale Energy Storage

Job Description

This role focuses on thermal management for lithium-ion battery energy storage systems within utility-scale Battery Energy Storage System (BESS) projects. You will support projects from initial design through commissioning, defining technical scope, providing engineering oversight, and acting as a key technical resource for cross-functional teams. The position combines strong analytical skills with a customer-service mindset to deliver high-performing, safe, and reliable energy storage solutions while continuously improving tools, standards, and processes.

Responsibilities

* Evaluate the design aspects of major components for utility-scale energy storage projects, with a focus on thermal management performance and reliability.

* Prepare detailed technical scopes of work for thermal management studies and designs, and incorporate these requirements into contract documents.

* Support projects from conception through commissioning, including participation in on-site commissioning activities for lithium-ion BESS installations.

* Provide engineering guidance and technical direction to internal project teams throughout the project lifecycle.

* Oversee and coordinate with external Engineers of Record to ensure designs meet project requirements, safety standards, and industry best practices.

* Collaborate with suppliers on equipment sizing, control strategies, technology compatibility, and integration of thermal management systems within BESS solutions.

* Partner with multi-disciplined teams to solve complex technical problems, optimize system integration, and drive process improvements across projects.

* Identify and evaluate value engineering opportunities to enhance performance, reduce cost, and improve constructability of energy storage projects.

* Monitor and assess emerging technologies in thermal management and energy storage to inform design standards and future project approaches.

* Capture lessons learned from completed projects and translate them into updated tools, standards, and best practices to maximize BESS performance.

* Communicate technical concepts clearly to both technical and non-technical stakeholders, supporting informed decision-making.

* Perform other job-related engineering duties as assigned in support of the Utility Scale Energy Storage team.

Essential Skills

* Demonstrated experience in thermal design and thermal analysis for complex mechanical or energy systems.

* Strong experience in mechanical engineering principles applied to thermal management and HVAC systems.

* Subject matter expertise in thermal management for energy storage systems, including one or more of the following: hydronic HVAC, air-cooled HVAC, battery heat generation and dissipation, or BESS design.

* Hands-on experience with VRF (Variable Refrigerant Flow), hydronic, and air-side HVAC systems.

* Strong knowledge of energy storage technologies, including lithium-ion battery chemistries, power conversion units, and DC/DC converters.

* Familiarity with relevant safety standards and codes, including UL1973, UL9540, NFPA 855, NFPA 70E, NEC, and applicable IFC/IBC sections.

* Proven ability to communicate technical concepts effectively to diverse audiences, both in writing and verbally.

* B.S. in Mechanical Engineering or a related field from an ABET-accredited program.

* At least 5 years of engineering experience, preferably in energy storage, thermal management, or related mechanical systems.

Additional

Skills & Qualifications

* Experience working on utility-scale solar or energy storage projects and understanding of their integration with BESS.

* Ability to define engineering scope and requirements for thermal management systems within large, complex projects.

* Experience collaborating with cross-functional and multi-disciplined teams, including suppliers and external engineering partners.

* Track record of identifying process improvements, developing tools and standards, and implementing lessons learned across projects.

* Strong analytical and problem-solving skills, with a detail-oriented and methodical approach.

* Customer-service…
