• Drive interconnection and grid-code compliance (IEEE, NFPA, NEC, UL, NERC), working with regulatory and compliance teams 

• Maintain power systems studies, integration guides, and customer-facing documentation 

• Travel to sites to support commissioning and issue resolution 

What You'll Bring (Qualifications) 

• Bachelor’s degree in Electrical Engineering 

• 8+ years in power systems engineering, with experience in utility-scale energy storage, grid interconnection, or data center power infrastructure 

• PE (Professional Engineer) license, or actively pursuing licensure 

• Expert knowledge of AC/DC power distribution, protection and control, and grid interconnection (fluent in both high-level architecture and detailed-analysis levels) 

• Experience with power systems analysis tools (ETAP, PSCAD, SKM, PSS/E, or equivalent) 

• Proven track record of customer-facing technical communication with utility and infrastructure customers 

• Working knowledge of IEEE 1547, IEEE 2800, IEEE 2030, NEC, NFPA 70/855, UL 9540, UL 1741 

• Comfort operating with ambiguous or undefined challenges  

Preferred Qualifications 

• Master’s degree in electrical engineering. 

• Experience with power systems for utility interconnection or data center projects 

• Background in BESS commissioning and grid-tied inverter systems (PCS, PMS, EMS integration) 

• Familiarity with grid-forming inverter behavior and islanding/microgrid operation 

• Familiarity with utility interconnection agreements, FERC/NERC compliance, and ISO/RTO market rules 

• Experience with requirements management tools (Jama, Polarion, or similar)
