Senior Critical Environment Technician

Overview
As a Senior Critical Environment Technician (CET) within Microsoft’s Cloud Operations & Innovation (CO+I) organization, you will play a key role in maintaining the critical infrastructure that keeps Microsoft datacenters operational, safe, and reliable. Senior CETs are trusted technical specialists who operate with a high degree of autonomy and are expected to lead through expertise, strong operational judgment, and disciplined execution.
In this role, you will work hands‑on with critical environment systems while coordinating closely with site leadership, engineering teams, vendors, and other critical facilities professionals. Responsibilities range from advanced maintenance activities and real‑time incident response to mentoring junior technicians and supporting risk, safety, and operational decision‑making. You will use telemetry, building management systems, and other monitoring platforms to assess equipment performance and ensure operational stability.
Cloud Operations & Innovation (CO+I) is the engine that powers Microsoft’s global cloud services, delivering the foundational infrastructure behind products such as Microsoft Azure, Microsoft 365, Bing, Xbox, and OneDrive. CO+I operates a global portfolio of more than 200 datacenters across 32 countries, supporting millions of servers and providing services to over one billion customers and 20 million businesses worldwide.
Microsoft’s datacenters are designed and operated with reliability, safety, and sustainability as core principles. Senior CETs contribute directly to these goals by ensuring systems operate within defined standards, identifying risks early, and supporting continuous improvement of operational practices as Microsoft continues to scale as a world‑class cloud provider.
Microsoft’s mission is to empower every person and every organization on the planet to achieve more. We work with a growth mindset, collaborate across teams, and act with respect, integrity, and accountability to create an inclusive environment where everyone can thrive.
