Construction Manager

Amazon's Data Center Construction Manager (CM) supports the delivery of hyperscale data center projects from feasibility through commissioning handover — contributing to scope, schedule, and budget management across new builds and capital upgrades in the Greater Kanto region. Amazon designs and procures its most advanced infrastructure in-house and builds data centers purpose-built for our own servers. As part of a dedicated, self-perform construction team, you will operate in a global environment, developing hands-on expertise across the critical infrastructure chain: HV substations, fiber, generators, switchgear, UPS, chillers, cooling towers, AHUs, and servers. Working under the guidance of senior Construction Managers, you will help hold general contractors (GCs) accountable to quality standards and support efforts to maintain schedule without sacrificing safety or resilience. Once construction is complete, you will support the facility's transition to the commissioning team through to handover. You will work within a high-velocity, multi-disciplinary team — owning defined project areas end-to-end while building your technical foundation across the broader program.
