Solutions Engineer – Energy Storage Systems (Entry-Level)

Location: Manteno, IL
Department: Energy Storage Solutions / Engineering
Employment Type: Full-Time
Level: Entry Level (0–2 years)

About the Role

The Entry-Level Solutions Engineer – Energy Storage Systems (ESS) plays a key role in supporting the design, integration, and delivery of battery energy storage solutions for commercial, industrial, and utility customers. This position assists senior engineers in system design, technical modeling, project proposals, and customer-facing technical support for lithium-ion and next-generation energy storage technologies.

You will collaborate with cross-functional teams—including product engineering, manufacturing, quality, and project management—to ensure ESS solutions meet customer requirements, safety standards, and performance specifications.

Key Responsibilities

Assist in designing battery energy storage system (BESS) configurations, including sizing, component selection, and performance modeling.

Support technical proposals, system layouts, and single-line diagrams for customer projects.

Conduct preliminary energy modeling, load analysis, and performance simulations.

Prepare technical documentation such as datasheets, drawings, integration guides, and system specifications.

Participate in customer meetings to gather technical requirements and translate them into engineering solutions.

Support field teams with system commissioning, troubleshooting, and performance verification (remote and on-site).

Conduct analysis to evaluate system efficiency, safety, and thermal performance.

Coordinate with manufacturing teams to ensure system designs align with production capabilities.

Assist with regulatory compliance (UL, IEEE, NFPA, NEC), safety reviews, and internal engineering standards.

Manage engineering documentation, testing reports, and project tracking tools.
