he Principal Data Center Infrastructure Engineer serves as a trusted technical authority within Amazon's global Infrastructure organization, specializing in availability assessment and system modeling across our worldwide data center network. This role combines deep analytical expertise with strategic leadership to evaluate complex infrastructure interdependencies and provide critical guidance on availability impacts, while setting the standard for engineering excellence across the organization.
The Principal DCIE serves as the technical authority for critical infrastructure availability analysis, developing comprehensive availability models based on system architectures, failure rates, and complex interdependencies between mechanical and electrical systems. You will assess the availability impacts of proposed Basis of design (BoD) design changes, equipment selections, and system architecture modifications through sophisticated modeling techniques, providing crucial insights that inform design decisions across the global data center engineering organization. Your expertise in calculating and understanding the intricate relationships between cooling systems, power distribution, controls infrastructure, and supporting mechanical systems will be essential in evaluating how changes in one domain affect overall facility availability and reliability, driving the development of new products.
Working closely with Global Design teams and partner organizations, you will analyze equipment failure modes, performance data, and unique challenges faced by our global expansion to provide strategic recommendations on availability optimization. Your comprehensive analysis will guide critical decisions on basis of design, Long Lead Equipment specifications, redundancy strategies, and system integration approaches that balance availability requirements with operational complexity.
