Battery Storage Integration Engineer – Utility Scale

Position Overview

We are seeking a highly motivated and technically skilled Battery Storage Integration Engineer to join our engineering team supporting utility-scale solar + storage EPC projects. The role will focus on the design, integration, and performance optimization of battery energy storage systems (BESS) within utility-scale renewable projects. The engineer will collaborate closely with cross-functional teams in engineering, procurement, construction, and operations to ensure safe, efficient, and cost-effective integration of energy storage systems.

Key Responsibilities

Design & Integration

• Develop, review, and optimize technical designs for battery energy storage systems in coordination with solar PV plants and grid interconnection requirements.


• Ensure compatibility of BESS with inverters, transformers, switchgear, SCADA, and grid control systems.


• Conduct load flow, short circuit, and protection studies related to BESS integration.


• Collaborate with OEMs and suppliers to specify battery technology, inverters, and other key equipment.

Project Support

• Provide technical guidance to project development and EPC teams on BESS scope, sizing, and system configurations.


• Review vendor drawings, specifications, and submittals to ensure compliance with project and industry standards.


• Support permitting and interconnection processes by preparing technical documentation and responding to utility/regulatory inquiries.


• Participate in factory acceptance tests (FATs), commissioning, and performance testing of battery systems.

Modeling & Performance Analysis

• Perform modeling and simulations of BESS performance under varying grid and operating scenarios.


• Analyze and optimize battery dispatch strategies for energy arbitrage, capacity, frequency response, and other ancillary services.


• Monitor, assess, and troubleshoot operational issues to ensure optimal performance of integrated solar + storage systems.

Compliance & Safety

• Ensure compliance with all codes, standards, and safety requirements (NEC, IEEE, NFPA, UL, and local regulations).


• Support the development of safety protocols and hazard analysis for BESS projects.

Collaboration & Continuous Improvement

• Work cross-functionally with project managers, procurement, and construction teams to ensure successful project execution.


• Stay current with emerging battery technologies, standards, and market trends to continuously improve design and implementation.

Qualifications

• Bachelor's degree in Electrical Engineering, Power Systems, Energy Systems, or related field (Master's preferred).


• Must have at least 3 years of BESS integration experience at a major BESS integrator in the US. 
• Must have proven BESS deployment experience in the US. Direct working experience on BMS.


• Strong hands-on experiences of lithium-ion batteries, inverters, PCS, EMS, and balance of plant systems.


• Hands-on experience with commissioning and operations of BESS projects.


• Familiarity with interconnection processes and utility requirements.


• Experience with EPC project lifecycle from design through commissioning preferred.


• Excellent problem-solving, analytical, and communication skills.


• Ability to work in a fast-paced, collaborative environment.

Preferred Skills

• Knowledge of hybrid solar + storage project integration.


• Familiarity with SCADA, communication protocols, and grid control systems.


• PE license or working toward licensure is a plus.
