• Instrumentation & Control Systems: Oversee installation of BMS, EPMS/power monitoring, DCIM, field instruments and sensors (temperature, humidity, pressure, flow, leak detection), PLC/control panels, and integration with mechanical systems.
• ELV & Network Infrastructure: Supervise grounding and lightning protection, fire alarm systems, CCTV, access control, and structured cabling (fiber and copper) pathways for data center network architecture.
• Construction Quality & Safety Compliance: Ensure all works comply with Thai electrical codes (EIT), utility requirements (PEA/MEA/EGAT), and international standards (e.g. IEC, NFPA 70/70E), including lockout/tagout and energization safety procedures.
• Testing & Commissioning: Witness insulation resistance and cable tests, protection relay testing, loop checks and instrument calibration, load bank testing, and Level 1-5 commissioning, including Integrated Systems Testing (IST) for power redundancy (N+1 / 2N).
• Technical Review & Problem-Solving: Review single-line diagrams, cable schedules, control philosophies, I/O lists, and vendor submittals; resolve design and installation issues with consultants and contractors.
• Material & Equipment Management: Track, foresee, and address the availability of long-lead equipment (transformers, switchgear, UPS, generators), from factory acceptance testing (FAT) through delivery and installation.

Job Qualifications

• Bachelor’s degree in Electrical Engineering, Instrumentation & Control Engineering, or a related field. A Thai Professional Engineer license (COE) is a plus.
• Minimum 3-10 years of experience in electrical and instrumentation works for large-scale infrastructure, power plant, industrial, or commercial projects (experience in data center projects is a plus but not required).
• Strong technical knowledge of power systems (MV/LV distribution, UPS, generators, protection), control and monitoring systems, and network architecture.
• Understanding of data center reliability concepts (Tier/redundancy design, power quality) and their interfaces with cooling systems.
• Strong leadership, problem-solving, and cross-cultural communication skills.
