BESS / Microgrid Engineer

GREENLINK ENERGY SOLUTIONS INC•Rockford, IL

11d•$100,000 - $130,000

About The Position

The BESS / Microgrid Engineer plays a critical technical role in the design and integration of advanced energy systems across Greenlink’s commercial project portfolio. This role focuses on the engineering, modeling, and performance optimization of battery energy storage systems, solar + storage integrations, and commercial microgrids. The engineer will work across the full project lifecycle—from early feasibility and system architecture through commissioning and operational validation. This is not purely a modeling or drafting role. The BESS / Microgrid Engineer is expected to apply independent engineering judgment, understand system-level interactions, and guide design decisions that ensure reliable, cost-effective, and resilient energy systems.

Requirements

Bachelor’s degree in Electrical Engineering or related technical field (or equivalent experience)
4+ years of experience in energy storage, power systems engineering, microgrids, or distributed energy systems
Strong understanding of battery energy storage systems, power conversion systems, and grid-interactive energy infrastructure
Experience designing or supporting solar + storage or microgrid projects
Familiarity with electrical system modeling tools or performance modeling methodologies
Working knowledge of NEC, interconnection requirements, and utility coordination
Ability to evaluate system behavior and make sound engineering decisions across multiple design constraints
Strong communication skills and ability to collaborate across technical and commercial teams

Nice To Haves

Experience with microgrid controls, grid-forming or grid-following inverter architectures
Familiarity with SCADA systems, EMS platforms, or microgrid control strategies
Experience integrating solar PV, storage, and building loads into coordinated systems
Exposure to commercial or industrial energy projects
Experience supporting TPO or financed energy infrastructure projects

Responsibilities

Lead technical design of battery energy storage systems and commercial microgrid architectures
Define system sizing, electrical configurations, and integration strategies for solar PV + storage and grid-interactive energy systems
Evaluate site electrical infrastructure, load characteristics, and operational objectives to determine optimal system design
Support selection of batteries, inverters, PCS systems, transformers, switchgear, and other balance-of-system components
Ensure designs meet applicable codes, AHJ requirements, and utility interconnection standards
Develop and validate performance models for energy storage and microgrid systems
Evaluate operational strategies, including peak shaving, load shifting, resiliency, and islanding capabilities
Analyze system stability and performance under normal operation and contingency scenarios
Support production modeling and long-term performance projections for project development and financing
Partner with Sales, Development, and Operations teams to support technical feasibility and system optimization
Work closely with solar engineers, electrical designers, and installation teams to ensure constructable designs
Evaluate vendor equipment specifications and performance characteristics
Provide technical guidance during procurement, installation, and commissioning phases
Identify technical risks early in project development and recommend mitigation strategies
Evaluate design tradeoffs related to performance, cost, resiliency, and operational flexibility
Support troubleshooting and root-cause analysis during commissioning and system operations
Maintain accurate documentation, system models, and as-built engineering records
Contribute to the development of engineering standards for storage and microgrid systems
Evaluate emerging technologies and integration strategies
Support internal knowledge development across solar, storage, and energy optimization platforms
