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
About You
- Have 5+ years of hands-on experience operating, maintaining, commissioning, or constructing mission-critical data centers, trading floors, or similar 24/7 facilities
- Have in-depth knowledge of MEP systems such as switchgear, UPSs, generators, STSs, PDUs, RPPs, chillers, CDUs, CRAH/CRAC units, pumps, fire protection systems, and BMS/EPMS
- 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
- Have a degree in a relevant engineering discipline (or equivalent critical facilities experience)
- Able to perform physical work, including lifting up to 50 lbs.

About this role
Jane Street's Chicago data center campus is expanding, and this role puts you at the center of that growth—operating live, mission-critical infrastructure while new facilities come online simultaneously. You'll own the day-to-day reliability of power, cooling, and monitoring systems across the campus, handling everything from routine equipment inspections and alarm response to troubleshooting complex MEP infrastructure and managing direct liquid cooling systems. The work is hands-on and collaborative, requiring you to coordinate across internal teams, external vendors, and the data center provider while also supporting construction and commissioning activities for new capacity.
This position demands someone with at least five years of hands-on experience in mission-critical facilities, with deep expertise in electrical and cooling systems, direct liquid cooling maintenance, and BMS/monitoring tools. You'll need to be comfortable writing and executing standard operating procedures, diagnosing problems under pressure, and communicating technical issues clearly to diverse stakeholders. The role includes on-call participation for 24/7 operations and willingness to work nights and weekends as needed.
The ideal candidate combines strong technical fundamentals—ideally a relevant engineering degree or equivalent critical facilities background—with construction and commissioning experience. You should be a self-starter comfortable working independently, capable of lifting up to 50 pounds, and able to make sound decisions when managing live infrastructure.
