About the Opportunity
Oikotechno is a fast-evolving IT infrastructure and data center solutions provider operating across Japan, delivering high-availability network, server, and telecom services to enterprise clients.

- Execute physical layer tasks — cabling (Cat6, fiber), rack mounting, labeling, power distribution, and asset tracking across client sites and colocation facilities.
- Support Layer 2/3 network deployment and validation, including VLANs, routing protocols (OSPF, BGP), and basic security policies under engineer supervision.
- Respond to high-priority infrastructure outages with rapid on-site resolution, documenting root cause and preventive actions for SLA compliance.
- Coordinate with remote network operations center (NOC) and vendors for escalation, parts delivery, and configuration handoff to ensure minimal downtime.
- Adhere strictly to safety, compliance, and change management protocols during all field activities across client and DC environments.
