Customer Success Specialist, Data Center

About DayOne 
DayOne builds and operates hyperscale data centers across nine markets in APAC and Europe. We raised US$4.5B in Series C funding and are in active build across the region. In Malaysia, that means real scale on the ground. 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. Across both campuses, the infrastructure supports some of the world's most advanced AI and digital technology, and the client partnerships behind it need the same precision as the build itself.
