About DayOne

DayOne builds and operates the data centers that AI, cloud, and digital economies run on. Our Hong Kong campus sits at the centre of one of Asia-Pacific's most connected cities — a global financial hub with some of the world's densest submarine cable landings. The infrastructure you maintain here supports critical digital services that businesses and communities across the region depend on every day.

Why DayOne

The team here knows what they're doing, the facility runs to high standards, and the work is genuinely significant — the infrastructure you look after keeps critical digital services online for enterprises and communities across the region. That's a different kind of shift work.

Good technical performance is recognised and rewarded. Strong technicians move into Senior Technician, Shift Supervisor, or regional engineering roles as DayOne grows. We back that with real investment: 40+ training hours per person per year, REW upgrade support, and vendor-led technical programmes.
