Infrastructure Engineer – Server & Cloud Operations | Major Enterprise in Tokyo

One of our best clients, a large and well-established enterprise in Tokyo, is looking for an Infrastructure Engineer to join its internal IT Operations team.

The company is currently undergoing a major digital and IT transformation, investing significantly in modernizing its internal technology environment and moving from traditional infrastructure operations toward a more cloud-oriented, standardized, and automated IT platform.

As part of this transformation, they are strengthening their internal infrastructure capabilities and are looking for an engineer who can support both the stable operation of the existing environment and the development of the company’s next-generation IT infrastructure.

This is not a position focused only on traditional server maintenance.

You will work across a hybrid environment combining on-premise infrastructure and cloud technologies, with opportunities to gain hands-on experience with modern enterprise solutions such as Microsoft 365, Entra ID, Intune, ServiceNow, Tanium, Azure, AWS, VMware, and automation technologies.

About the Team

The core team currently consists of 1 Manager and 1 Engineer, giving you the opportunity to take broad ownership rather than being limited to a narrow technical area.

The company is actively improving infrastructure visibility, standardization, and automation using solutions such as ServiceNow, Tanium, Microsoft 365, and Entra ID.

Responsibilities

Your responsibilities will include:

• Operation and administration of Windows Server and/or Linux environments
  
• Server, network, and authentication infrastructure operations
  
• Maintenance and modernization of data center and cloud environments
  
• IT asset and configuration management
  
• Improving visibility across the company’s IT infrastructure
  
• Standardization and optimization of IT operational processes

• Exploring the use of AI tools to improve IT operations
  
• Supporting infrastructure-related projects and new system implementations
  
• Vendor coordination and management
  
• Supporting the company’s transition toward a more cloud-native IT operating environment
  

The exact scope of responsibilities can be adjusted based on your experience and technical strengths.

You will take ownership of specific infrastructure areas and independently handle:

• Infrastructure operations
