Why DayOne

At DayOne Japan, technical excellence is the foundation everything is built on. You will work on infrastructure held to the highest standards of precision and reliability, with a clear path for development: structured training, meaningful scope, and career progression that is earned and respected. We are building here for the long term and growing the people who will carry that forward.

Construction & Development

• 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.

Operations

• 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.

Business & P&L

• 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.

Experience

• 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.

Leadership & Character

• 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.
