Role description

Description
AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we’re the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we’re looking for talented people who want to help.

You’ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You’ll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And you’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

AWS is looking for a detail-oriented individual to join our Data Center Engineering Operations (DCEO) Team. This committed group works to maintain the critical physical infrastructure that supports Amazon Web Services. Specifically, this team works to ensure that the data center's MEP operates at 100% availability while maintaining first-class customer service to the teams and groups within the data centers.

As the Data Center Engineering Operation (DCEO) Chief Engineer (CE), you will be responsible for ensuring that all electrical, mechanical, and fire/life safety equipment within the data center is operating at peak efficiency. This involves both planned preventative maintenance of equipment, daily corrective work, and emergency response to emergent issues. You will serves as an expert technical resource reporting to a site’s Data Center Facility Manager and interacting with onsite Engineering Operations Technicians (EOT) and any third party vendors. Being the singular focal point for all facility operations within a given data center, you will support Amazon within its owned and operated data centers. Data center equipment that supports mission-critical servers must maintain better than 99.999% uptime.

As the DCEO Chief Engineer you will manage small-to-medium impacting projects from conception to completion. These projects involve large amounts of independent work as well as collaboration with external support groups including engineering, automation, processing, and finance in both local and global settings. Creating and delivering on key milestones, obtaining and tracking quotes for all necessary costs, and documenting project results for future implementation at other facilities. The goals of such projects are for the CE to drive innovation and resiliency while reducing operational costs in the facilities.

One of the best parts to this role is that you will direct, train and support Engineering Operation Technicians in their role of providing hands-on electrical and mechanical equipment troubleshooting and operations. Implementation and execution of site/equipment-specific training exercises is also expected. This equipment includes, but is not limited to, stand-by diesel generators, MV/LV power distribution and switchgear, UPS’s, PDU’s, AHU’s, CRAHs, chillers, cooling towers, chemical treatment systems, pumps, motors, VFD’s, and building management systems (BMS).

Key job responsibilities

  • Oversee the day-to-day operations and maintenance of mechanical and electrical equipment in data centers
  • Operate independently with limited direct management
  • Assist in the design and build out of new facilities
  • Act as an escalation point for all facilities-related issues within the data center region and work OT hours as needed to support site stability
  • Perform root cause analysis of equipment failures
