As one of the fastest-growing companies in the industry, we've built a robust presence across Asia and Europe — and we're just getting started. This is more than a job — it's an opportunity to be a key contributor to our dynamic team and help shape the future of general data infrastructure. About DayOne DayOne is a global leader in the development and operation of high-performance data centers, operating across eight markets in Asia and Europe. Backed by US$4.5B in Series C funding, we are one of the fastest-growing companies in the industry, and Spain is central to our next chapter. Data center delivery lives and dies on the schedule. As our Planning Manager for Data Center Projects in Madrid, you own Critical Path Method (CPM) scheduling and schedule integrity across DayOne's active developments and future pipeline in Spain, from early-stage development through construction, commissioning, and operational readiness.



You will set the planning standard our PMCs and contractors work to, surface risks before they become delays, and give project leadership the schedule intelligence to make fast, informed decisions. This is a role for a planner from mission-critical or MEP-intensive construction who wants direct ownership on the client side of one of Europe's fastest-growing data center programs.
