• Fulfill process safety accountabilities by supporting and participating in HAZOPs, Management of Change (MOC), hazard analyses, and incident investigations.
• Support the development and execution of capital projects, and unit turnarounds, including early project scoping, technical input, startup support, and post‑implementation verification.
