Engineering Lead, AI Innovation Hub

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.

Benefits

• Subsidized health, dental, and vision insurance
• Equity (options) in a rapidly growing startup
• 401(k) with 4% employer match
• Unlimited PTO
• Parental leave
• Healthcare and Dependent Care Flexible Spending Accounts (FSA) or Health Savings Account (HSA)
• Commuter benefits
• Team on-sites where all offices come in–person to collaborate
