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

Nice To Haves

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)

Responsibilities

Serve as the engineering point-of-contact for site-level power systems throughout the product lifecycle and across installations
Conduct power systems studies, analyses, designs, and test plans including load flow, short-circuit, arc flash, protection coordination, and grounding studies using industry standard tools (PSS/E, PSCAD, ETAP, etc.)
Identify, evaluate, and select suppliers and partners to meet Peak’s objectives
Establish commissioning test plans and support commissioning execution
Support the analysis and resolution of site issues and failures, including root cause and corrective action (RCCA)
Define integration requirements for BESS deployments including grid connection, protection, load profiles, fault ride-through, and backup/UPS architectures
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
