Join DayOne – Shaping the Future of Data Infrastructure

DayOne is a global 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.

• Lead end-to-end delivery of DayOne's data center development — from site development and design through commissioning and handover.
• Drive project schedules, budgets, and quality standards; hold GCs and engineering partners accountable to milestones.
• Build and maintain relationships with local authorities, utilities, and regulatory bodies to ensure permits, grid access, and compliance — particularly critical in Japan's complex power procurement environment.
• Embed a culture of safety across all construction sites that reflects DayOne's values and meets the highest international standards.

• Oversee day-to-day operations of live data center facilities, ensuring maximum uptime, SLA compliance, and customer satisfaction — meeting DayOne's standard of precision-engineered performance.
• Build and scale the Japan operations team; recruit, develop, and retain the talent that will define DayOne Japan's culture.
• Implement and continuously improve operational processes, leveraging the latest innovations in data center technology — from advanced cooling systems to software-driven uptime management.

• Own Japan's full P&L — revenue, cost management, and margin accountability. You are the senior decision-maker in market.
• Act as DayOne's primary point of contact for hyperscale customers and strategic partners in Japan; resolve escalations, deepen relationships, and exceed expectations.
• Collaborate with the CEO and global leadership on Japan's pipeline strategy, land acquisition, and long-term growth roadmap — positioning Japan as a cornerstone of DayOne's APAC network.
• Monitor market trends, competitive dynamics, and technology developments to inform business decisions and stay ahead of Japan's rapidly evolving digital infrastructure landscape.

• 15+ years of experience in data center construction, development, or critical infrastructure — with meaningful time in a senior leadership role with full P&L or budget accountability.
• Proven track record delivering large-scale construction or development projects on time and within budget. You have built something significant and can show it.
• Deep familiarity with the Japan market — local authority relationships, utility negotiations, permitting processes, and the nuances of operating in Japan's business environment.
• Experience building and leading cross-functional teams that include contractors, engineering partners, and vendors across complex, multi-stakeholder environments.

• Entrepreneurial mindset — you thrive in lean, fast-moving environments where you can make decisions and see results. You do not need a committee to move.
• Results-oriented and hands-on. You set the standard by doing, not just directing.
• Strong communicator and influencer — equally effective with site teams, hyperscaler C-suites, Japanese government officials, and DayOne's global leadership.
• Bilingual in Japanese and English (written and spoken). Based in Japan or willing to relocate.
• A passion for building something lasting — DayOne's mission of sustainable, zero-carbon data center infrastructure is not just a strategy; it is how we build.

DayOne is proud to be an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
