Lead Electrical Engineer

Why join Giga

• The Pace: We're building at a speed most companies talk about but never actually operate at. If you've been bored somewhere else, you won't be here.
• The Impact: Every person at Giga touches the work that matters. No layers, no waiting for approval chains. You'll see your fingerprints on what we ship.
• The Team: A team of operators defining the future of AI infrastructure. We recruit A-players from the most innovative companies in the world, and they choose Giga because the work here means more.
• The Moment: AI doesn't run without power, and that's us. Giga is the picks and shovels behind the AI revolution. This industry is about to explode, and you'll be in the room where it's already happening.

What you'll do

Giga's mission is to manufacture data centers to support the AI ramp. We're moving beyond traditional construction to a product-based approach, designing and mass-producing high-performance infrastructure that can keep pace with the exponential demand for compute. As Lead Electrical Engineer, you'll own the power architecture and electrical DNA of these next-generation facilities.

This is a rare opportunity to define the electrical backbone of a rapidly scaling infrastructure company. You won't just be managing a single 50 MW build—you'll be creating the Plan of Record (POR) for Giga Data Centers, a standardized, manufactured product that will be deployed globally.

You'll set the standard for high-density AI power delivery, designing medium and low voltage distribution, backup generation, and UPS systems that can handle the most demanding compute workloads on the planet. The AI ramp is the defining industrial challenge of our time, and you'll build the engine that powers it. Your designs will be manufactured and deployed rapidly, with direct impact visible across hundreds of facilities.

Where you'll work

If based outside of our Houston, Long Beach, Reno, or San Francisco hubs, this role will be based remotely from your home office. You must be willing to travel as needed to our job sites and to one of our hub offices.

Responsibilities

• Develop and maintain the electrical POR for Giga Data Centers, defining the "Gold Standard" design that enables manufacturing of reliability and efficiency at scale.
• Author and own the internal engineering library including technical specifications and Basis of Design documents for all power systems, establishing what we build and how we measure success.
• Design to global and local standards, ensuring strict compliance with the NEC (NFPA 70), NFPA 70E, and IEEE standards for mission-critical power distribution.
• Guide external engineering (A&E) firms to localize designs while maintaining strict adherence to core power performance intent and standardization requirements.
• Execute rigorous power system studies, including load flow, short circuit, protective device coordination, and arc flash analysis to ensure system resilience and safety.
• Engineer complex, high-density power distribution topologies (Medium Voltage down to the rack PDU) aligned with OCP (Open Compute Project) specifications for AI interoperability.
• Select and specify medium/low voltage switchgear, generators, UPS systems, transformers, ATS/STS units, and high-ampacity busways for high-density compute environments.
• Create detailed Bills of Material (BOMs), Quantity Take Offs (QTOs), and Commissioning scripts to support a manufacturing-first supply chain.
• Develop Sequence of Operations (SOO) and Control Narratives for EPMS/BMS integration, dictating how electrical systems respond to utility failures and dynamic AI load changes.
• Use advanced simula
