Job description

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.

About the Role

DayOne is building its flagship hyperscale data center campus in Lahti, on a former industrial site in Kiveriö. The campus is designed to use Finland's naturally cool climate for free cooling, with air-cooled chillers that remove the need for freshwater cooling. Join the Lahti team early and help shape how a campus of this scale is built, commissioned, and run.

As a Shift Manager, you will be responsible for ensuring the efficient and reliable operation of the data center facility. You will lead shift teams, oversee equipment inspections and operational reviews, analyze critical systems, and ensure consistent execution of operating procedures and incident management processes.

We operate in a 24/7 environment. This is not a shift role, but occasional out-of-hours response and coverage will be required.

• Ensuring smooth coordination and execution of daily operational activities.

Equipment and Operational Review

• Reviewing facility equipment inspections completed by shift teams.
• Verifying operational and maintenance data for accuracy.
• Overseeing shift handover information, including event, fault, alarm, capacity, and redundancy reviews.

Systems Analysis

• Analyzing usage and interface issues within BMS, building automation, high-voltage monitoring, inspection PDA, and data center management systems.
• Identifying improvement opportunities related to BMS and low-voltage control systems.

Training and Procedure Compliance

• Coordinating and monitoring training activities according to established plans.
• Evaluating training outcomes and ensuring compliance with SOPs and EOPs.
• Supporting the development of operational readiness and technical competency.

Incident Management

• Recording and analyzing abnormal operating conditions and incident reports.
• Identifying root causes, documenting solutions, and sharing lessons learned across teams.
• Supporting the continuous improvement of emergency response practices.

Requirements
