Lead Instrumentation and Controls Engineer

About Giga

Giga builds the electrical infrastructure that powers the modern world. We manufacture transformers, switchboards, and modular data centers for customers across the United States and the globe. Together, our team combines fresh perspectives with deep industry experience to solve real-world problems for our customers. We move fast and think practically. If you're ready to make an impact in an industry that matters, we're looking for people like you.

• The Pace: You will manage projects moving faster than anywhere else in the industry.
• The Impact: You are the person who turns "concepts" into "contracts" and "permits."
• The Team: Work with a world-class group of engineers defining the future of AI infrastructure.

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 Controls Engineer, you'll define the nervous system of these facilities.

You won't just be programming a single building—you'll be defining the Controls Plan of Record (POR) for a mass-manufactured product. You'll take mechanical and electrical intent and translate it into a robust, scalable control architecture that can be replicated across megawatts of infrastructure globally.

This is a role for an engineer who understands that a great mechanical design is only as good as the control system that drives it. You'll design the intelligence that keeps massive AI clusters alive, architecting control systems with security, reliability, and performance as first principles. Your standards will be replicated across hundreds of deployments worldwide.

If based outside of our Houston, Long Beach or San Francisco hubs, this role will be based remotely from your home office. You must be willing to occasionally travel to one of our hub offices 3 days out of the month.

• Establish the standardized control architecture for Giga's mass-manufactured data center product line, creating systems that scale across global deployments
• Review P&IDs and One-Line Diagrams to identify every controllable device, ensuring strict adherence to ISA-5.1 standards for consistent documentation across all facilities
• Define exact control interfaces for all field devices from liquid cooling loops to power systems, leveraging IEC 61850 standards for power utility automation and seamless integration of protection relays and smart breakers
• Oversee panel design ensuring compliance with UL 508A (Industrial Control Panels) and NEMA/IP ratings for harsh environments
• Implement IEC 62443 (Cybersecurity for Industrial Automation and Control Systems) standards to segment networks, harden devices, and secure remote access against cyber-physical threats
• Create high-performance operator interfaces using ISA-101 (HMI Design) and ISA-18.2 (Alarm Management) to prevent alarm floods and ensure rapid response to critical AI load events
• Design redundancy and reliability logic to ensure systems survive controller failures or sensor drift without impacting critical compute loads
• Collaborate with mechanical/electrical teams to refine SOO, translating narratives into detailed logic diagrams (Functional Block/Ladder) compliant with IEC 61131-3
• Develop I&C functional test scripts and support commissioning teams during Level 3-5 testing to validate that physical reality matches design intent
• Create comprehensive control system documentation including instrument loop diagrams per ISA-5.4, ensuring manufacturability and maintainability at scale

• Bachelor's degree in Electrical, Mechanical, or Mechatronics Engineering
• 7+ years of experience in I&C design for mission-critical facilities, power plants, or industrial manufacturing
• Working knowledge of IEC 62443/ISA-99 frameworks for OT cybersecurity
• Proficiency with ISA-5.1 for P& and ISA-5.4 for instrument loop diagrams
• Strong knowledge of industrial communication protocols (Modbus TCP/RTU, BACnet/IP, SNMP, OPC UA)
• Experience specifying VFDs, PLCs (Allen-Bradley, Siemens), and EPMS/SCADA…
