Senior Power Systems Engineer, Grid Interconnection & Storage

Ll Oefentherapie; United States; On-site; USD 120,000 - 160,000; Full time

Job summary

Ll Oefentherapie seeks a senior Power Systems Engineer to design and evaluate power architectures for data-center-like campuses, integrating utility interconnection, energy storage, and on-site generation. You will develop requirements, perform validations, and guide fleet-scale solutions with a focus on reliability and scalability.

The role requires coordinating with utilities, engineering partners, and site stakeholders to optimize capacity, resiliency, and energization timelines.

Qualifications

• Experience in power-system architectures for utility supply and campus interfaces.
• Ability to translate grid and power-system issues into clear recommendations.
• Familiarity with interconnection facilities, substations, grounding and protection.

Responsibilities

• Develop and assess power-system architectures for utility supply, substations, energy storage, load management, on-site generation, and campus electrical interfaces.
• Produce technical requirements, design criteria, calculations, specifications, and engineering recommendations for site-specific and repeatable fleet solutions.
• Apply established engineering standards and contribute to global design philosophies, modeling methods, acceptance criteria, and validation practices.
• Identify technical risks and opportunities affecting capacity, schedule, resiliency, operability, and future expansion.
• Translate complex grid and power-system issues into clear technical recommendations for stakeholders.
• Perform evaluations of utility capacity, transmission and distribution infrastructure, substations, reliability, power quality, and expansion needs.
• Support engagement with utilities and ISOs/RTOs on interconnection and power-delivery solutions.
• Define requirements for interconnection facilities, substations, protection and controls, grounding, and campus interfaces.
• Evaluate alternatives to accelerate energization and unlock capacity.
• Provide technical analyses to Energy Contracting during negotiations.
• Conduct power-system due diligence for prospective data-center sites.
• Develop conceptual power architectures and compare site alternatives during development.
• Assess interconnection complexity, reliability, power quality, and expansion potential.
• Partner with Real Estate, Site Development, Capacity Planning, and Energy Contracting to integrate feasibility into decisions.
• Develop engineering analyses for battery energy storage systems on sizing, controls, safety, and lifecycle performance.
• Evaluate BESS use cases including resiliency, grid support, load management, and capacity optimization.
• Analyze load-curtailment, demand-response, and peak-reduction opportunities with utilities.
• Develop architectures coordinating utility supply, data-center load, BESS, UPS, and on-site generation.
• Support engineering of natural-gas generation, fuel cells, microgrids, renewables, and emerging tech.
• Evaluate generation configuration, synchronization, protection, controls, and islanding; assess emissions constraints.
