• Build strong working relationships with stakeholders and communicate complex EHS risks clearly, translating technical findings into practical safety solutions.
• Degree in a relevant engineering, EHS or technical discipline.
• 8+ years' EHS experience supporting engineering projects, construction upgrades or major plant modifications.
• Demonstrable construction and capital project experience, including shutdowns, turnarounds and contractor-intensive work.
• Strong ability to read and interpret engineering drawings, including P&IDs, PFDs, GA layouts, electrical and mechanical drawings.
• Solid knowledge of process safety, technical risk assessment, HAZOP/PHA and design safety reviews.
• Proven experience in contractor management, RAMS reviews, PTW systems, LOTO and high-risk work controls.
