Principal Mechanical Operations Engineer – Data Centers
This is a full-time exempt (40+ hours/week), remote role within the United States with travel as required.
Summary
We are seeking a Principal Mechanical Operations Engineer to serve as the senior technical authority for mechanical and cooling infrastructure across a rapidly expanding portfolio of hyperscale AI data centers. This role will provide operational leadership for critical cooling systems, establish mechanical readiness standards, and ensure successful transition of facilities from commissioning into steady-state operations.
The successful candidate will drive operational excellence across chilled water plants, cooling towers, liquid cooling systems, CDUs, pumps, CRAH/CRAC infrastructure, and other mission-critical mechanical systems. This position will also play a key role in evaluating site readiness, conducting operational audits, supporting future facility designs, and developing scalable operational standards as the data center portfolio continues to grow.
