EIRE Systems is working with an international Data Center Services company, a recent entrant shaping the future of the Tokyo hyper-scale data center market.

We’re seeking to hire a consultant Network Engineer to design and build network infrastructure from the ground up—supporting corporate IT, facility systems, and physical security platforms in a brand-new DC environment.
This is not BAU. This is a true greenfield project where you’ll own design decisions and see your work go live.

What You’ll Do

• Design core, access, and OOB network architecture for a new data center platform
• Build networks supporting IT, BMS, access control, and security systems
• Work closely with vendors, carriers, and construction teams to deliver the build
• Lead design reviews, validate installations, and support commissioning
• Ensure everything is ready for handover into operations

What We’re Looking For

• Solid experience in network engineering (L2/L3, routing, switching)
• Experience in data center environments (design or deployment)
• Ability to work in project-based, multi-vendor builds
• Strong communication skills; able to coordinate across stakeholders

Why Join

• Greenfield build in a high-growth hyperscale market
• Full lifecycle exposure: design → build → go-live
• Work on critical infrastructure beyond IT (facilities + security systems)
• Opportunity to make a real impact in a new DC platform in Japan

Location: Tokyo area
Language: English required; Japanese a strong plus

***Applicants must presently be residing in Japan with permission to work full-time in Japan.
