About DayOne Data Centers

Why DayOne?
The Chonburi campus is one of the most significant data center builds in Southeast Asia right now, and this role has full end-to-end ownership of it — from initiation through to live handover. You’ll work inside a technically demanding, multi-contractor environment, on infrastructure that will run for decades. DayOne is a well-funded company at an active growth stage — the people who deliver well here build their careers here too.
About the Role
You’ll lead data center construction projects end to end, from initiation through commissioning and handover — owning scope, budget, schedule, and the full contractor and vendor ecosystem on site. This is a senior delivery role for someone who has run mission-critical construction before and can operate fluently within a technically demanding, multi-contractor environment from day one.
Project Leadership

• Lead end-to-end data center construction projects from initiation through commissioning and handover.
• Develop detailed project scopes, budgets, schedules, and resource plans.
• Manage internal teams, external vendors, contractors, engineers, and consultants across the full project lifecycle.

Delivery and Quality Control

• Monitor construction progress against design specifications, codes, and standards.
• Oversee quality control, health and safety, and change management processes throughout the build.
• Ensure all permitting, inspections, and regulatory requirements are met on schedule.

Commissioning and Handover

• Coordinate commissioning and integration of electrical, mechanical, and IT systems.
• Track and report on project milestones, deliverables, and risk factors.
• Manage financial tracking, budget adherence, and cost optimization across the project.
• Ensure project documentation, closeout reports, and handover to operations are completed to standard.

Requirements
Technical Skills

• 8 or more years of project management experience in data center, semiconductor, or comparable high-precision, high-availability construction environments — this is a hard requirement, not a preference.
• Proven experience managing large-scale construction projects with significant mechanical and electrical complexity.
• Experience working with Japanese contractor or EPC firms is required given the contractor ecosystem in Thailand’s Eastern Economic Corridor.
• Strong working knowledge of MS Project, Primavera P6, AutoCAD or Revit, and BIM tools.
• PMP or equivalent certification is preferred.
• Bachelor’s degree in Construction Management, Engineering, Architecture, or a related field.
• English required. Thai strongly preferred for site-level coordination and local authority engagement.

Soft Skills

• Explains their own project experience with enough technical specificity to be assessed on it, not just described in general terms.
• Leads multi-contractor teams with the authority to resolve conflicts and keep schedule without escalating every issue upward.
• Manages competing project priorities in a fast-paced, high-stakes construction environment without losing quality discipline.

Nice to Have

• Experience with hyperscale or colocation data center construction specifically.
• Understanding of IT, networking, and cabling requirements in data center environments.
• Experience managing multiple concurrent projects in parallel.
