Summary of the Role

The Sr. Manager, Project HSSE ensures the RGLNG project executes all work with necessary HSSE processes to achieve project goals related to safety, environmental, regulatory permitting, health, security and emergency response. This position manages efforts in HSSE execution‑related contractual expectations of the EPC Contractor, as well as leading the HSSE function for the Owners E&C Site Team. This role requires a close working relationship with the EPC Contractor and will act as a focal point for Project HSSE compliance. The Sr. Manager, Project HSSE will play a critical leadership role in the transition from construction through commissioning, startup, and into early operations (CSU). This includes ensuring that HSSE processes evolve appropriately from construction safety to encompass commissioning and process safety risks, with a clear focus on managing high‑consequence hazards during system energization, introduction of hydrocarbons, and SIMOPS activities.

The role requires a strong understanding of Energy Based Safety (EBS) principles and their application to both construction and commissioning environments, ensuring that controls are in place to manage hazardous energy sources and prevent serious injury and fatality (SIF) events.

The Sr Manager, Project HSSE will support the Corporate HSSE discipline within the company to ensure necessary processes are developed and implemented to support the Project construction phase, through commissioning and startup into operations.

This position is based in Brownsville, TX.
