In alignment with Microsoft’s values, we are committed to cultivating an inclusive work environment for all employees to positively impact our culture every day—and we need you as a CE Lease Operation Manager (CELOM). In this role, you will lead and develop a team of Critical Environment Field Service Engineers (CE FSEs) and ensure safe, compliant, and reliable operations of mission-critical mechanical and electrical infrastructure across assigned datacenter sites. You will serve as a key operations leader across sites—driving standardization of maintenance execution, change/risk management rigor, audit readiness, incident response excellence, and continuous improvement. This opportunity will allow you to strengthen operational resilience, improve cost/energy efficiency, and grow a high-performing technical team in a highly regulated, always-on environment. Microsoft’s Cloud Operations & Innovation (CO+I) is the engine that powers our cloud services. As a CO+I CE Lease Operation Manager (CELOM), you will perform a key role in delivering the core infrastructure and foundational technologies for Microsoft's online services including Bing, Office 365, Xbox, OneDrive, and the Microsoft Azure platform.
Job Responsibility:
Lead, coach, and develop CE FSEs by setting clear expectations, driving accountability, supporting career growth, and sustaining strong engagement and performance
Define and track clear performance metrics for CE FSE execution quality, including MOP review rigor, maintenance record quality, audit finding closure, and incident recurrence trends
Own workforce planning activities including recruitment, onboarding, training, development, and succession planning for CE FSE roles
Ensure CE FSEs consistently execute day-to-day operations and maintenance of mechanical, electrical, and plumbing (MEP) systems across assigned sites, protecting availability and operational readiness
Ensure CE FSEs conduct thorough, line-by-line technical and risk-based reviews of EOPs/SOPs/MOPs, validating assumptions, failure modes, critical switching steps and rollback plans prior to execution
Oversee implementation and governance of annual maintenance, break-fix, technical MEP projects and drive improvements (timeliness, accuracy, and execution quality) where gaps exist
Supervise compliance to change management policies by ensuring critical work is properly planned, reviewed, and controlled—especially landlord/site maintenance activities executed under Microsoft governance
Lead risk management across safety, operational, and compliance requirements (e.g., certifications, renewals, readiness gaps), escalating and driving mitigation plans through closure
Promote and enforce electrical/mechanical safety practices for both landlord and Microsoft-owned equipment, ensuring the team is trained and consistently operating to expectations
Ensure regular emergency drills are planned, executed, reviewed, and improved, validating role clarity, accountability, and readiness across Microsoft and landlord teams
Oversee development and dissemination of RCA (Root Cause Analysis) and incident learnings, driving preventive actions that reduce recurrence risk and improve operational maturity
Drive a culture of continuous improvement, including follow-up on findings from assessments, audits, QA/compliance checks, and insurance/CEP-related requirements
Act as the primary people-manager interface between site CE FSE teams and Regional CE / Engineering functions
Ensure operational feedback (incidents, RCAs, maintenance findings, audit outcomes) is systematically fed into regional engineering and global standards
Ensure quality control of critical maintenance records, validating completeness, accuracy, and audit readiness across all assigned sites
Represent CE operations in cross-functional forums, sharing lessons learned and driving CE-related programs that improve safety, reliability, and consistency
Build and maintain strong partnerships with landlords, site operations leadership and regional/global stakeholders, serving as the primary CE people-manager escalation path
Participate in and maintain structured lessor performance governance, including scorecards, trend analysis, and escalation of recurring operational or compliance risks
Support and coordinate infrastructure upgrades and deployments (e.g., capacity-related changes) by aligning CE readiness, execution dependencies, and operational acceptance criteria
Ensure accurate data management in relevant facility planning tools and support future deployment and capacity planning activities through disciplined operational inputs
Ensure CE FSE participation in design reviews, commissioning activities, and site transitions in line with the Site Transition Program, validating operational readiness prior to BAU handover
Requirements:
Demonstrated experience managing mission-critical physical operations in a Critical Environment infrastructure (e.g., electrical/mechanical plant operations and maintenance) and driving operational rigor across multiple sites
Experience leading and motivating a diverse technical workforce, including performance management, coaching, and team capability development
Working knowledge of change and risk management in critical environments, including reviewing/approving work controls and ensuring safe execution
Willingness to support flexible hours / non-business hours as required by the rhythm of the business and incident response needs
Ability to meet Microsoft/customer/government security screening requirements where applicable (e.g., Cloud Background Check requirements referenced in Microsoft Careers postings)
Fluency in Japanese and English language skills for high levels of engagement and extensive interaction with internal and external stakeholders
Nice to have:
Bachelor’s Degree or Technical College certification in mechanical or electrical engineering and/or services
Experience driving standardization of EOP/SOP/MOP procedures, maintenance calendars, and cross-site best practices
Experience leading audit/assessment readiness and closure, including corrective action planning and verification
Demonstrated success delivering energy efficiency / cost optimization initiatives and tracking outcomes
Strong stakeholder management skills with landlords, site ops leaders, and regional/global partners
