Construction Manager, Electrical

About the Role

DayOne is building Thailand's first 1-gigawatt data center campus in Chon Buri. Phase 1 (60MW) is already energized. The full program runs through 2028. We need an experienced Electrical Construction Manager to own all electrical deliverables — from design through to commissioning — and see them through to the end.

You'll report to the Project Director and lead engineers, technicians, consultants, and subcontractors on-site. Design work is a mix of in-house technical ownership and consultant-managed delivery work. You'll be the senior technical authority directing and reviewing output, not starting from scratch.

Responsibilities

What You'll Own

Design & Planning

• Own electrical design plans, specifications, and schematics in compliance with Thai codes and international standards (NEC, IEC)
• Evaluate systems for Tier-level compliance, N+1 and 2N redundancy requirements
• Use BIM to manage MEP coordination and catch clashes at design stage, not on site

Construction & Oversight

• Lead all electrical construction — HV/LV, critical power, UPS, generators, switchgear, and substation
• Manage subcontractors, site teams, and LLE sequencing to protect program and cost
• Conduct site inspections; troubleshoot issues before they escalate

Budget & Cost Control

• Own cost estimates and budget proposals for all electrical packages
• Monitor spend and drive cost efficiency without compromising quality or safety
• Support tender evaluation and contract negotiation

Compliance & Safety

• Ensure full compliance with Thai regulations and EHS standards throughout
• Manage local permitting and coordinate with Thai regulatory authorities

Testing & Commissioning

• Lead CxM, integrated systems testing, and sign-off across all critical electrical infrastructure
• Ensure SOO, QA/QC, and all documentation are audit-ready at every phase

Reporting

• Keep the Project Director informed with accurate, timely progress and technical reports
• Maintain complete project records — changes, approvals, costs, and defects

Requirements

• Bachelor's degree in Electrical Engineering
• 5–7 years on mission-critical projects — data centers, pharmaceutical, hospital, or cleanroom
• Hands-on experience with DC delivery cycles, Tier standards, N+1/2N redundancy, and critical power
• Proven track record leading CxM and integrated systems testing
• Proficient in AutoCAD, Revit, and MS Project or Primavera
• Comfortable with BIM coordination and MEP clash detection
• Budget and cost control experience on EPC projects
• Familiar with Thai permitting and regulatory requirements
• Fluent Thai · Strong business English

Nice-to-Haves

• Advanced degree or professional engineering certification (PE license or equivalent)
• Experience with DCIM platforms and BMS integration
• Familiarity with prefabrication and long-lead equipment management
• BIM experience and exposure to multi-phase program delivery
