    • Risk assessments
    • HAZOP/HCCP and similar reviews
    • 3D model review and coordination
    • Preparing sequences of operations and reviewing functional specifications
  • Participate in cross-discipline and discipline-specific checks for small projects of intermediate complexity, ensuring overall project quality.
  • Mentor junior engineers and design staff.
  • Lead system design programming and planning with support from senior team members.

Qualifications
