About the Position

We are looking for an experienced Data Center Operations Engineer to join a highly technical group responsible for operating and maintaining our rapidly scaling data center infrastructure.

This is a hands-on role supporting live, mission-critical facilities while additional data halls and buildings are constructed and commissioned on the same campus. This is a role based at our mission-critical data center campus in Chicago. You will support the live portions of the campus, helping us keep live infrastructure operating reliably while bringing new capacity safely into service.

Our team is collaborative in nature, spanning many internal departments and external vendors, contractors, consultants, and operations teams. Your work will cover all aspects of our complex data center environments, including working with advanced power and cooling systems.

Additional responsibilities of the role will include:

Operating and maintaining live data center environments, including regular equipment inspections, alarm response, incident response, and follow-up

Troubleshooting cooling, power, controls, and monitoring issues at the cabinet, pod, and facility levels

Supporting and maintaining CDUs, RDHx units, and direct liquid cooling infrastructure, including hands-on tasks such as filter replacement, valve and hose checks, and leak response

Monitoring operations through internal BMS and monitoring tools, investigating abnormal conditions, and escalating issues with clear technical context

Reviewing, executing, and improving SOPs, EOPs, and MOPs in coordination with internal teams, data center providers, and specialist vendors

Planning and coordinating preventative and reactive maintenance, supervising critical work, and confirming that equipment is returned to service correctly

Acting as the primary day-to-day liaison with the data center provider and coordinating vendors performing work on site for our scope of work

Supporting construction and commissioning activities for new data halls, including site walks, drawing and submittal review, script review, witnessing tests, and construction-to-operations turnover

Have a strong understanding of data center cooling and electrical principles, including redundancy topologies, containment, airflow management, and liquid cooling

Experienced with maintaining and troubleshooting direct liquid cooling systems, including CDUs, RDHx units, valves, hoses, filters, and associated controls

Comfortable using BMS and monitoring tools to investigate alarms, identify trends, and diagnose equipment or system problems

Experienced with writing, reviewing, and executing SOPs, EOPs, and MOPs

Proven able to work effectively with data center providers, contractors, OEMs, and service vendors

A strong problem-solver and communicator with the ability to describe detailed problems with brevity and accuracy

A self-starter who works well independently, prioritizes effectively, and makes sound judgment calls under pressure

Flexible to work nights and weekends in support of 24x7x365 operations and willing to participate in an on-call rotation for critical site emergencies
