What You’Ll Do

We are seeking a skilled and hands-on Data Center Facilities Manager 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.
