Job Summary

The Senior EHS Specialist will be the primary on-site guardian for health, safety, and environmental compliance during the construction of a large-scale data center. You will ensure that all construction activities—from civil works to MEP fit-out—adhere strictly to local regulations, corporate EHS standards, and OSHA and ISO guidelines. Your goal is to achieve a zero-incident workplace.

Key Responsibilities

1. Site Safety Management

• Implement and enforce the project-specific EHS plan and behavioral safety programs.

• Conduct daily site walkthroughs and safety audits, focusing on high-risk activities: crane lifts, working at heights, excavation, hot work (welding), and scaffolding.

• Lead the permitting process for high-hazard tasks (Confined Space Entry, Hot Work Permits, LOTO/energization).

• Monitor subcontractor compliance; stop work immediately if unsafe conditions are observed.

• Site inspection and audit.

2. Incident Management & Investigation

• Manage the incident reporting system (near-misses, first aid, recordables).

• Conduct thorough root-cause investigations for any safety incidents.

• Track corrective actions to closure and ensure lessons learned are shared across the project team.

3. Training & Induction

• Develop and deliver site-specific safety orientations for all new personnel (including GC, MEP, and security staff).

• Facilitate toolbox talks (TBT) on critical topics such as arc flash prevention, fall protection, and heat stress management.

• Ensure all workers possess valid qualifications (e.g., WAH certification, forklift licenses).

4. Environmental Compliance

• Monitor environmental controls related to erosion, sediment control, and stormwater management (SWPPP).

• Oversee waste management protocols, ensuring proper segregation and disposal of hazardous materials (oil, batteries, chemicals).

• Ensure compliance with noise and dust control measures to minimize community impact.

• Develop, implement, and maintain the Vector Management Control Program​ to mitigate the risk of vector-borne diseases.

5. Reporting & Meetings

• Prepare monthly EHS statistics (TRIR, DART) and present them to senior leadership.

• Chair weekly EHS coordination meetings with General Contractors and key MEP subcontractors.

• Liaise with local regulatory authorities (MOM, OSHA, HSE) during inspections.

Qualifications & Requirements

• Minimum 5 years​ of progressive EHS experience.

• Proven experience in large-scale construction​. Experience in Data Centers, Oil & Gas, or Semiconductor Fab​ is highly preferred over standard commercial building experience.

• Experience managing EHS during high-voltage electrical installations​ (33kV/132kV switchyards) is a strong plus.

• Bachelor’s or diploma’s degree in Occupational Safety, Environmental Science, or Engineering.

• In-depth knowledge of ISO 45001 (Safety)​ and ISO 14001 (Environment).

• First Aid/CPR/AED certified instructor level is a plus.
