You’ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles.

Data center equipment that supports mission-critical servers must maintain better than 99.999% uptime. As the 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.

This equipment includes, but is not limited to, stand‑by diesel generators, switchgear, UPS’s, PDU’s, AHU’s, chillers, cooling towers, chemical treatment systems, pumps, motors, VFD’s, and building automation systems. Oversee the day‑to‑day operations and maintenance of mechanical and electrical equipment in a data center. Operate independently with limited direct management. Act as an escalation point for all facilities‑related issues within the data center, escalating to the Data Center Facility Manager as needed. Perform root cause analysis of equipment failures. Troubleshoot and report facility and data sever‑level events within internal SLA. Create and deploy new standard practices for Engineering Operations Technicians, Chief Engineers, and vendor support teams. Provide training and guidance to Engineering Operations Technicians. Ensure all safety procedures are adhered to by vendor and Amazon staff. Utilize internal CMMS to manage building workflows. Communicate complex technical information to a non‑technical audience. This role is carried out in an operational site environment and may involve working at height, moving around uneven surfaces, and handling tools or materials in line with HSA manual handling guidelines.
