Benefits: Access to benefits package

Pay Range: $140,000 - $160,000 USD

Summary:

Seeking a Power Engineer for Energy Storage to support and help grow this expanding practice. Responsible for the engineering delivery of Battery Energy Storage System (BESS), microgrid, and other inverter-based resource (IBR) interconnections across utility, renewable, data center, and industrial markets, from concept through construction, commissioning, and energization.

Responsibilities

• Engineer for Battery Energy Storage System (BESS) projects. Perform detailed design, analysis, and engineering of BESS, microgrid, and other inverter-based resource (IBR) systems, ensuring compliance with customer requirements, utility requirements, industry standards, codes and regulations.
• Collaborate with multidisciplinary teams to integrate BESS and IBR designs seamlessly into larger electrical systems, including substation, generation, and grid interconnection infrastructure.
• Support technical scoping, design, and utility/developer coordination for Battery Energy Storage System (BESS), microgrid, and other inverter-based resource (IBR) interconnections at the medium- and high-voltage level, including protection philosophy, interconnection studies, and compliance with IEEE 1547 / IEEE 2800.
• BESS one-line, three-line, and AC/DC schematics.
• Physical layouts, equipment arrangements, and site plans for containerized/modular BESS installations.
• DC architecture including battery racks, inverters/power conversion systems (PCS), and medium-voltage collection systems.
• Grounding systems and electrical safety designs.
• Protection & control philosophies, relay schemes, and coordination.
• BESS/microgrid interconnection one-lines, protection & control schemes, and anti-islanding / transfer trip logic.
• Fire detection/suppression and thermal management coordination with mechanical disciplines.
• Develop and review equipment specifications for major BESS components including battery modules, power conversion systems (PCS), transformers, switchgear, protection relays, and communications/SCADA systems.
• Perform complex engineering studies with general guidance.
• Perform and/or direct short-circuit, arc flash (IEEE 1584), harmonic (IEEE 519), power flow, and EMT/transient (e.g., PSCAD or equivalent) studies, including fault, harmonic, and dynamic contribution from BESS and other inverter-based resources.
• Support interconnection application processes and LGIA/SGIA coordination with utilities, developers, and BESS vendors.
• Use AutoCAD and Revit software to prepare drawings and visual aids.
• Support timely and effective coordination of the project design team, including resource forecasting.
• Identify potential project scope changes and aid in development of strategies to minimize impact and control deviations from estimated costs and project deadlines.
• Work closely with clients to understand their specific project requirements, provide technical insights, and ensure client satisfaction throughout the project lifecycle.
• Support resolution of design, construction, and field issues.
• Support construction, testing, commissioning, and energization through RFIs, field engineering, and technical troubleshooting.
• Participate in technical reviews, design meetings, and client presentations.
• Prepare project design and construction documents.
• Prepare project progress reports for internal and external stakeholders.
• Update and maintain shop drawing and RFI log.
• Identify opportunities and lead the strategic use of technology, digital platforms, and AI-enabled tools to enhance efficiency through workflow automation, reduced manual effort, and improved accuracy in forecasting, documentation, reporting, and quality processes.

Qualifications

• 5+ years of progressive energy storage or power systems engineering experience, with demonstrated depth in protection & control (P&C) design.
• BS in Electrical Engineering.
• Professional Engineer (PE) license in Electrical Engineering.
• Experience supporting engineering delivery on medium- to high-voltage BESS, microgrid, or IBR interconnection projects
• Hands-on protective relay experience (SEL or equivalent platform), including settings development and coordination.
• Direct experience navigating LGIA/SGIA processes and utility interconnection requirements.
• Experience supporting multidisciplinary BESS or power systems design and working on utility, renewable, data center, or industrial projects
• Knowledge of medium- and high-voltage electrical systems including BESS, microgrid, and IBR configurations, protection & control philosophies, and utility-scale grounding and electrical safety design. Knowledge of various electrical topologies and distribution systems
• Strong working knowledge of applicable electrical codes and standards, specifically NESC, NEC, NFPA (including NFPA 855 for battery energy storage systems), ANSI, and utility interconnection standards, along with IEEE 1547 and IEEE 2800 (interconnection of inverter-based resources), IEEE 1584 (arc flash), IEEE 519 (harmonics), and IEEE 80 (substation grounding grid design), with ability to apply requirements through code analysis and system design.
• Knowledge of power systems engineering / design software including short-circuit, arc flash, harmonic, and power flow analysis tools (e.g., ETAP, SKM, or ASPEN), equipment sizing, and EMT/transient simulation (e.g., PSCAD or equivalent)
• Strong working knowledge of Battery Energy Storage Systems (BESS), microgrids, and inverter-based resource (IBR) interconnection requirements, including protection coordination, anti-islanding/transfer trip schemes, and utility interconnection processes (LGIA/SGIA)
