Join DayOne – Shaping the Future of Data Infrastructure

DayOne is a general leader in the development and operation of high-performance data centers. 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.

As we expand into new international markets, we’re looking for talented, driven individuals to join us on this exciting journey. 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 global data infrastructure.

If you're passionate about innovation, technology, and growth, we invite you to be part of DayOne’s next chapter.

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.

We build at hyperscale speed. That means real complexity, real timelines, and real accountability,



alongside the resources and backing to deliver.

The Role

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.
