Fleet is headquartered in Denver, Colorado, with satellite offices in Seattle, WA and Arlington, VA.

As a Senior High Voltage (HV) and/or Medium Voltage (MV) Electrical Engineer, you will lead complex power system design and optimization for high/medium voltage substations, transformers, and critical power infrastructure supporting hyperscale data centers. You will oversee the development and deployment of electrical infrastructure projects, ensure compliance with industry standards, and collaborate with cross-functional teams to optimize data center performance and efficiency.

This is a hands‑on role with significant responsibility for the strategic direction, design, and implementation of electrical infrastructure for data centers in different global regions. The ideal candidate will be a technical expert in substation engineering, with a deep understanding of data center operations, sustainability initiatives, and reliability requirements. This role will be primarily focused on the design and construction of High Voltage (HV) and Medium Voltage (MV) substations.

Engineers at Fleet Data Centers work to design resilient, cost‑effective electrical distribution systems. We are responsible for achieving a world class uptime for our customers. We justify and communicate the technical decisions we make to senior management and work hard to drive continuous advancements and improvements with our designs.

• As required, engage with customers for preferred performance and architectural design parameters to inform substation and distribution system design.
• Lead the design and optimization of high and medium voltage substations for data centers, including the specification of transformers, switch gear, protective relaying, bus duct systems, controls, and grounding schemes.
• Oversee the selection and integration of high voltage (HV) and medium voltage (MV) equipment to maintain optimal uptime and efficiency.
• Drive large‑scale power infrastructure projects from conceptual design through detailed engineering, construction, and commissioning.

• Provide technical leadership for electrical power systems, focusing on reliability, redundancy, scalability, and innovation in design practices.
• Implement best practices in fault analysis, load flow studies, short circuit analysis, and relay coordination to ensure system reliability.
• Champion the adoption of renewable energy and innovative power technologies, working closely with renewable energy providers to integrate green power sources.

• Define and enforce global standards for HV/MV substation design, installation, and operation to ensure consistency across multiple data centers.
• Ensure compliance with local, national, and international codes and standards (e.g., NEC, IEEE, NERC, IEC, UL) for power system installations, environmental considerations, and safety regulations.
• Collaborate with regulatory authorities, utilities, and EPC contractors to secure approvals for HV/MV electrical designs and manage interfaces between data centers and the power grid.
