Senior Project Manager, Data Center Construction

About DayOne

DayOne builds and operates hyperscale data centers across nine markets in APAC and Europe. We raised US$4.5B in Series C funding and are in active build across the region. In Chonburi, we are developing one of Southeast Asia's most significant greenfield data center campuses on a path to Thailand's first 1GW platform. This role leads that build.

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.
