Site EHS Manager – BESS Project (Dual Civil & High-Voltage Focus)

Location: Ako, Hyogo Prefecture, Japan (100% Site-Based)

Position Type: Full-time, Project-Based

Reports To: Project Director

Language Requirement: Native or Fluent Japanese & Business-level English

Job Purpose

The Site EHS Manager will lead all safety operations for the utility-scale Battery Energy

Storage System (BESS) project in Ako. This complex infrastructure project demands a rare

dual-expertise: managing high-risk heavy civil works and deep foundation engineering

during the initial phases, and seamlessly transitioning to supervise high-voltage (HV)

electrical installation, substation integration, and energization phases. The candidate

ensures a zero-incident environment across both engineering disciplines.

Key Responsibilities:

Civil Works & Structural Infrastructure Safety
- Oversight of Earthworks & Excavation: Monitor heavy excavation, slope stability,

retaining wall construction, and deep trenching. Enforce strict shoring requirements

to prevent soil collapse.




- Heavy Equipment & Traffic Segregation: Manage a high volume of heavy

machinery (excavators, piling rigs, concrete trucks) and establish foolproof traffic

plans to separate heavy plant machinery from ground workers.
- Foundation & Structural Civil Works: Supervise the structural integrity of deep

piling and the pouring of massive reinforced concrete pads engineered to support

heavy battery enclosures.
- Heavy Lifting Operations: Review and approve critical rigging and heavy-crane lift

plans for placing high-tonnage battery containers, transformers, and electrical

skids.

High-Voltage Electrical & Commissioning Safety

• Lock-Out/Tag-Out (LOTO) Governance: Establish, audit, and strictly enforce the

site’s LOTO and Permit-to-Work (PTW) systems during electrical fit-out and testing.
- Arc Flash & High-Voltage Hazards: Enforce personal protective equipment (PPE)

compliance, safe approach distances, and boundary con
