Job Description
Hybrid Space–Liquid Cooling Mechanical Operations Manager
Location: Spartanburg, SC (On-Site)
The Company
Our client is a privately backed organization operating at the forefront of high-performance computing (HPC) and advanced data center infrastructure. The company designs, builds, and operates mission-critical environments that support next-generation compute workloads, enabling large-scale research, simulation, analytics, and AI-driven innovation.
The Position
The Hybrid Space–Liquid Cooling Mechanical Operations Manager will serve as the senior authority responsible for the operation, maintenance, and performance optimization of advanced liquid cooling systems supporting high-density compute environments within a High-Performance Compute Center (HPCC).
This role leads an internal team of subject matter experts (SMEs), along with third-party service providers, responsible for owner-directed operations and maintenance of hybrid space cooling systems. These systems include direct-to-chip liquid cooling, Coolant Distribution Units (CDUs), Rear Door Heat Exchangers (RDHXs), and associated mechanical and control systems.
The position ensures reliable and efficient thermal performance by coordinating closely with Mechanical, Electrical, and Controls teams that support upstream chilled water, power, and control infrastructure.
This role also owns technical water system chemistry management, ensuring corrosion control, biological stability, and fluid quality in accordance with manufacturer requirements and system design standards. The ideal candidate combines deep technical expertise in advanced cooling technologies and industrial fluid systems with strong leadership capabilities in a 24/7 mission-critical environment.
