Job Purpose

To drive and execute end-to-end engineering projects across the plant lifecycle—managing technical development, layout optimization, equipment integration, planning, on-site installation, and commissioning.

*

Planning & Procurement Support: Establish detailed Work Breakdown Structures and schedules in MS Project, support tendering packages (RFPs/RFQs), and conduct rigorous technical bid evaluations.

*

On-Site Installation & Site Safety: Supervise mechanical, electrical, and facility installation work, strictly enforcing Mars Safety and Quality & Food Safety (Q&FS) policies.

*

Permit-to-Work Oversight: Issue and manage high-risk work permits on-site, including hot works, working at height, and confined space entries.

*

Testing, Commissioning & Handover: Lead and execute Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), ramp-up trials, and final operational handover with complete as-built CAD documentation.

*

Governance & Budget Tracking: Actively track milestone deliverables and capex expenditure against plan, mitigating variance risks and delivering structured reporting to project leadership
