Reliability Engineer, Mechanical Systems

Location: Dallas, Texas (Headquarters)
Functions: Data Center Operations

The Reliability Engineering Team is responsible for the overall health of critical systems across Stream facilities.  For each of the major systems Electrical, Mechanical, and Controls, the Reliability Engineering team is responsible for ensuring success in the commissioning stages of new construction, evaluating and improving the reliability and performance of existing critical infrastructure, sustaining equipment operational availability through maintenance programming, providing technical support to the Site Operations Teams, and providing systems reliability and maintainability feedback to the Design Engineering teams for future design considerations.

The Reliability Engineer Mechanical Systems is responsible for the overall operational health of critical cooling systems. This responsibility includes oversight of facility acceptance testing, mechanical system maintenance planning, and Facility Operations technical support. Requirements for this position include full familiarity with mechanical systems arrangements, equipment types, system automation and control components.  The Reliability Engineer candidate understands component failures and the extended effects of those failures on the larger cooling system as well as appropriate mitigating actions.  Also required is an understanding of cooling system theory, an ability to read drawings and schematics, and an ability to identify likely failure points in design.  The mechanical reliability engineer acts as an advisor for Site Operations to reference as needed and has enough experience to train technicians to the level of effective troubleshooting.  The mechanical systems Reliability Engineer regularly interfaces the Stream Data Centers Design Engineering team, the Automation Systems Group, and Facility Operations teams.

Stream Data Centers powers, cools, protects, and connects the technology of the world’s well-known hyperscale data companies, cloud providers and large enterprises. Developing and operating across eight markets in North America. Stream has evolved data center design in innovative ways to deliver dramatic gains in reliability, efficiency and sustainability in flexible environments that can scale as quickly as the market demands. Stream’s business is growing exponentially, through a combination of greenfield market expansion and acquisitions across North America.
