About the Role – Staff Power Systems Engineer
We're looking for a power systems electrical engineer to own the electrical architecture, integration, and deployment of our energy storage site across applications, including utilities and data centers, as examples. You'll define architectures; functional, operational, and availability requirements; interface requirements with other power systems; installation requirements; and SCADA (supervisory control and data acquisition) requirements.
You will work closely with ESS Engineering, Business Development, and Project Execution, to translate customer requirements into system designs, ensuring our products meet customer standards such as utilities and data centers. This is a highly visible role with significant customer-facing responsibility. The ideal candidate is a deeply knowledgeable power systems engineer who is equally comfortable presenting to technical and non-technical customer teams as they are conducting in-depth research and analysis.
What You'll Do (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, as examples
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)
Peak Energy is committed to building a diverse and inclusive workforce. We strongly encourage women, people of color, and individuals from underrepresented groups to apply.
