This position offers an exciting opportunity to join a team dedicated to the reliability and availability of AWS critical infrastructure, serving millions of customers worldwide.

AWS Infrastructure Services (AIS)
AWS Infrastructure Services is responsible for the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we are the people who keep the cloud running. We support all AWS data centers as well as all the servers, storage equipment, networks, power systems, and cooling systems that ensure our customers have continuous access to the innovations they rely on. We work on the most complex problems, with thousands of variables impacting our operations, and we are looking for talent who want to help us tackle these challenges.

You will join a diverse team of software, hardware, and network engineers, critical systems specialists, security experts, operations managers, and other essential roles.

• Record state changes in critical infrastructure as part of corrective and preventive maintenance operations.
• Perform quality, performance, safety, and reliability testing of products, equipment, and processes.
• Serve as first-line responder for troubleshooting electrical and mechanical equipment: air handling units (AHUs), chillers, cooling towers, chemical treatment systems, pumps, motors, variable frequency drives (VFDs), and building management systems (BMS).
• Define and maintain the highest safety standards, and actively promote a world-class safety culture in all aspects of operational procedures.
• Drive continuous improvement efforts for infrastructure through standardization of procedures and policies, while ensuring performance against defined metrics.
• Enable the operations organization to achieve 100% uptime across all customer-supporting infrastructure.
• Collaborate effectively with internal and external stakeholders to ensure operational excellence for all AWS customers.
• Ensure the planning and execution of preventive maintenance on critical infrastructure according to AWS procedures.
• Ensure facility supervision and monitoring (via BMS, PMS, surveillance rounds, etc.).
• Actively participate in the delivery of construction and renovation projects for data center infrastructure.
• Ensure the organization's ability to respond appropriately to any event that may impact customers, on any electrical or mechanical component.
• Analyze incident reports, document periodic trends, and formulate recommendations to management.
• Write, update, and maintain operating procedures, standard operating procedures (SOPs), emergency procedures, preventive maintenance programs, and all technical documentation related to DCEO.
