Engineering Lead, AI Innovation Hub

About Giga

Giga is building gigawatts of AI data centers to hasten a future of intelligence and abundance. We build data centers fast and at scale by combining the capabilities of an equipment supplier, engineering firm, general contractor, and real estate developer under one roof. Our team moves quickly and thinks practically. If you're ready to make an impact in an industry that matters, we're looking for people like you.

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

We are seeking a skilled and hands-on Data Center Facilities Technician with facilities experience to manage the operations of our pilot data center. This role requires a proactive individual who can perform mechanical work, oversee the maintenance of equipment, and coordinate with subcontractors as needed.

Where you’ll work

We are an in-office culture — velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is ideally based in our San Francisco, offices, with full-time onsite expectations outside of bi-weekly WFH Fridays.

We're onsite because velocity matters when you're building physical infrastructure. Solving complex problems in real-time with Manufacturing, Engineering, and Finance leaders is how we move faster than a slow, antiquated industry.

Responsibilities

• Oversee the daily operations of the data center, ensuring all systems function optimally.

• Monitor and maintain air-cooled chillers, CDU systems and fan coils.

• Perform hands-on mechanical tasks, including maintenance, repairs, and troubleshooting of facility systems.

• Conduct routine inspections to identify and resolve potential issues before they escalate.

• Engage and coordinate with subcontractors for specialized tasks or repairs.

• Serve as the primary point of contact for all facility-related inquiries and issues.

• Maintain accurate records of maintenance activities, equipment performance, and service requests.

• Assist in developing standard operating procedures (SOPs) for facility operations.

• Ensure compliance with safety regulations and best practices within the facility.

• Promote a safe working environment for all personnel and visitors.

Requirements

• High school diploma or equivalent; technical certification in facilities management, HVAC, or related field preferred.

• Minimum of 3 years of experience in facilities management or data center operations.

• Hands-on experience with mechanical systems, cooling technologies, and electrical systems.

• Strong troubleshooting and problem-solving abilities.

• Excellent communication skills for effective collaboration with team members and subcontractors.

• Ability to work independently and manage multiple tasks efficiently.

• Relevant certifications in HVAC, electrical systems, or facilities management are a plus.

• Proficiency with "filling and infilling" (often referred to as commissioning and topping off) using specialized equipment like the Liquid Cooling Cart. This includes:

• Performing full rack fills, drains, and air purges to remove trapped air.

• Handling 60-liter reservoirs and managing separate "new" vs. "used" fluid to prevent contamination.

• Experience with PG25 specifically, which is often dyed fluorescent yellow-green for rapid visual leak detection. Technicians must monitor pressure drops and flow rates, as PG25’s viscosity can sometimes mask small leaks.

• Awareness of "wetted materials" like copper cold plates, brass, and polymer piping (PP or PVDF) to prevent corrosion or biofouling.

• Ability to service Coolant Distribution Units (CDUs) and rack manifolds, including the use of Quick Disconnect (QD) or LQC connectors for spill-free maintenance.

Bonus points

• Ideally 2–6+ years in data centers, high-performance computing (HPC) facilities, or industrial cooling.

• Certificates:

• EPA 608 Universal Certification: Standard for handling refrigerants and cooling systems.

• Familiarity with standards like NFPA 110(emergency power) and ASHRAE.

• Hands-on experience with plumbing, pump maintenance, and troubleshooting integrated electrical/mechanical systems.
