About The Position

The BESS / Microgrid Engineer is responsible for engineering, modeling, and optimizing battery energy storage systems, solar-plus-storage integrations, and commercial microgrids across Greenlink Energy Solutions’ commercial project portfolio. The role spans the project lifecycle, from feasibility and system architecture through commissioning and operational validation. It requires independent engineering judgment and a system-level understanding to guide reliable, cost-effective, and resilient design decisions. The engineer leads system design and sizing, evaluates site infrastructure and load characteristics, models system performance and operating strategies, and supports equipment selection and utility interconnection. The role collaborates with Sales, Development, Operations, solar engineers, electrical designers, installation teams, and vendors. It also involves identifying and mitigating technical risks, supporting procurement, installation, commissioning, and troubleshooting, maintaining engineering documentation, and contributing to engineering standards and internal knowledge development. The position requires a bachelor’s degree in Electrical Engineering or a related technical field, or equivalent experience, and at least four years of relevant experience. The salary range is $100,000–$130,000 per year, depending on experience. Benefits include health, dental, and vision insurance, a 401(k), paid time off, and life insurance.

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 plus storage and grid-interactive energy systems.
Evaluate site electrical infrastructure, load characteristics, and operational objectives to determine system designs.
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 and contingency scenarios.
Support production modeling and long-term performance projections for project development and financing.
Collaborate with Sales, Development, Operations, solar engineers, electrical designers, and installation teams on feasibility, optimization, and constructable designs.
Evaluate vendor equipment specifications and performance characteristics.
Provide technical guidance during procurement, installation, and commissioning.
Identify technical risks and recommend mitigation strategies.
Evaluate design tradeoffs involving 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 engineering standards for storage and microgrid systems.
Evaluate emerging technologies and integration strategies.
Support internal knowledge development across solar, storage, and energy optimization platforms.
