About the Role |
The EHS Site Representative (SSR) serves as the on-site client representative for EHS compliance on active data center construction projects. Embedded within the project team and reporting to the Assistant Director of Field Safety, the SSR is the primary safety authority on site — acting as the owner's representative to ensure that all construction activities are executed in strict conformance with applicable federal, state, and local safety regulations, project-specific EHS requirements, and the client's safety standards.
This is a highly visible, field-intensive role requiring sound technical judgment, strong communication skills, and the credibility to influence contractor and subcontractor behavior at all levels. The SSR is expected to build a safety-first culture on site, proactively identify and eliminate hazards before incidents occur, and serve as a trusted advisor to the project team on all EHS matters specific to the unique risks of hyperscale and enterprise data center construction. The candidate must be able to operate effectively in a dynamic, high-intensity environment while supporting the project team in achieving delivery milestones safely. |
