About DayOne

Behind every app, every AI tool, every connected experience, there is a data center. DayOne builds them. In Malaysia, DayOne is already doing exactly that at scale. As Johor's largest LEED-certified data center operator, we run two campuses at Nusajaya Tech Park and Kempas Tech Park, at the heart of the SIJORI cross-border digital corridor connecting Singapore, Johor, and Batam. Backed by US$4.5B+ in Series C funding, we are operational, growing, and building the team to match.

About The Role

You'll own day-to-day operations across multiple data centers within the Johor Bahru cluster — accountable for uptime, team performance, compliance, and the operational standard that DayOne's SLAs are built on. This is a senior leadership role. You manage the shift teams, own the maintenance program, drive compliance across ISMS, SOC2, and PCI DSS, and support the Campus Director on strategic initiatives that shape how the cluster performs long term.

Track operational metrics, analyze performance data, and identify risks before they affect operations or client commitments.
Implement and continuously improve operational policies, procedures, and best practices across all sites.

Team Leadership

Lead, mentor, and develop a team of operations and technical staff across the cluster, building a culture of technical excellence and continuous improvement.
Coordinate with shift teams to ensure seamless 24/7 coverage and effective handovers across all operational periods.
Conduct regular training sessions and performance evaluations to strengthen team capability and accountability.

Maintenance and Vendor Management

Plan and oversee preventive and corrective maintenance across all equipment and systems, ensuring servicing meets manufacturer and DayOne standards.
Coordinate with vendors and contractors for maintenance and upgrade works, delivering projects with minimal impact on live operations.

Safety and Compliance

Ensure all cluster operations comply with health, safety, and environmental regulations and maintain audit-ready documentation at all times.
Maintain active compliance with site accreditations including ISMS, SOC2, and PCI DSS across all cluster sites.

Customer and Strategic Support
