About the role

LiquidStack is a fast-growing technology company delivering advanced liquid cooling solutions for mission‑critical data center and high‑performance computing environments.
This highly visible, hands-on role goes beyond break/fix service.
The Senior FST independently executes complex field work, mentors junior technicians, and serves as on-site technical authority during installations, commissioning, outages, and critical events.

Perform advanced troubleshooting across mechanical, hydronic, electrical, controls, and thermal subsystems; isolate root cause across hardware, software, power, fluid quality, or environmental factors
Operate diagnostic instrumentation (multimeters, megohmmeters, manometers, IR cameras, refrigerant recovery, flow meters, pressure transducers); lead pressure testing, flow balancing, fluid fills, leak checks, and acceptance testing during commissioning
Read and work from electrical schematics, P&IDs, mechanical drawings, and sequence-of-operations documents; redline drawings when as-built conditions differ from design
Support customer acceptance testing and formal system handover
Deliver basic operational training and system overviews to customer technical teams; field technical questions and represent product capability accurately
Partner with Engineering, Manufacturing, Quality and Supply Chain to resolve recurring field issues; contribute to service procedures, checklist, and training materials
Use service ticketing systems (e.g., ServiceNow, Salesforce Field Service, or equivalent) to track work, log time against tasks, document resolutions, and ensure timely closure; maintain SLA compliance and clean shift handoffs to ensure continuity of operations

LiquidStack provides product-specific orientation but no foundational trade, certification, or technical-skills training outside of required safety programs.

Prior experience with hyperscale, colocation, or enterprise data center operators (e.g., Equinix, Digital Realty, Flexential, CoreSite, Compass, QTS); NOC/SOC/IOC or DCT II/III experience a plus

OSHA 10 (General Industry) required
OSHA 30 and NFPA 70E (arc flash) strongly preferred and may be required by customer sites before performing energized electrical work
