Lead Power Systems Engineer, Data Centers

Energy Vault is a global energy storage and power infrastructure company focused on delivering reliable, flexible power solutions. The Lead Power Systems Engineer for Data Centers is responsible for designing power architecture and ensuring the reliability and safety of data center power infrastructure, while integrating various energy resources.

Responsibilities:

• Identify relevant design criteria for high availability power system supplying data centers
• Define and own the overall power system architecture for data centers from utility point of interconnection through IT load
• Design high-reliability substations aligned with Tier III / Tier IV reliability standards for up to 50MW data centers
• Lead failure modes and effects analysis (FMEA), short-circuit studies, coordination studies, and reliability assessments
• Ensure systems are designed for maintainability without downtime, including concurrent maintenance strategies
• Support black-start, islanded operation, and degraded-mode operating scenarios where applicable
• Design on-site or co-located generation, including: diesel or gas turbine generators; Battery energy storage systems (BESS); Co-located or on-site photovoltaic (PV) systems
• Define control strategies for dispatch, load-shedding, islanding, resynchronization, and grid interaction
• Coordinate integration of DERs with UPS systems, static switches, and data hall distribution
• Lead technical engagement with utilities, ISOs/RTOs, and interconnection authorities
• Support interconnection studies, protection coordination with utility systems, and compliance with grid requirements
• Interface with EPCs, OEMs, and equipment suppliers to ensure design intent is preserved through execution
• Establish and maintain design standards, reference architectures, and technical guidelines across multiple sites or regions
• Provide technical oversight during design reviews, FATs, SATs, commissioning, and energization
• Support operational teams with troubleshooting, root-cause analysis, and system upgrades over the asset lifecycle
• Work cross-functionally with engineering, legal, commercial, and executive teams to align project goals

Requirements:

• Bachelor's degree in Electrical or Power Systems engineering
