Lead Electrical Engineer

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.

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 simulation tools to optimize power system reliability and validate designs before manufacturing.

Requirements

• Professional Engineer (PE) license required.
• Bachelor's or Master's degree in Electrical Engineering.
• 7+ years of electrical engineering experience with a strong focus on mission-critical, data center, or heavy industrial facilities.
• Deep working knowledge of the National Electrical Code (NEC/NFPA 70) and relevant IEEE standards.
• Strong background in electrical system analysis using tools like ETAP, SKM PowerTools, or EasyPower.
• Experience with relay programming and protection coordination schemes.
• Proficiency in Revit/AutoCAD for electrical design.
• Proven ability to create engineering standards from scratch rather than just copying legacy reference designs.
• Strong understanding of high-density power solutions (100kW+ racks) and modern data center topologies (distributed redundant, block redundant, etc.).
• Experience specifying heavy electrical equipment including MV/LV switchgear, generators, and large-scale UPS systems.
• Track record developing standardized designs for scalable deployment.

Bonus points

• Understanding of OCP (Open Compute Project) power initiatives, including Open Rack architectures and 48V DC power shelves.
• Experience with utility grid interconnection and medium/high voltage substation design.
• Background in Electrical Power Monitoring Systems (EPMS) and SCADA integration.
• Experience with a manufacturing-first design approach (DfMA principles).
• Startup or high-growth company experience
• A clear preference for hands-on building over administrative management.
• Track record creating Plans of Record for manufactured products.
• Experience managing A&E firms and maintaining design standards across partners.
• Familiarity with Level 1-5 commissioning processes and integrated systems testing (IST) for electrical infrastructure.
• Experience with design-build or fast-track project delivery.
