Objective

The Project Engineering Manager (Thailand) holds ultimate accountability for the engineering design, technical execution, and physical commissioning of the Thailand plant. Operating as a critical functional leader under Group guidance (reporting to Sirius Project Delivery Director), this role bridges global engineering standards with local execution and supports the Project Delivery Director in the execution of the project.

The successful candidate will manage multi-million dollar capital budgets, coordinate Tier-1 contract engineering firms, oversee equipment suppliers, and drive the cross-functional coordination required to deliver a high-performing, compliant, and operationally ready industrial plant.

Scope of Work (SOW) & Boundaries

Lifecycle Ownership: Complete end-to-end ownership of the plant's lifecycle, balancing strategic project management with active, hands-on site involvement, direct troubleshooting, and field implementation from Detailed Engineering Design ➡️ Procurement ➡️ Field Construction ➡️ Commissioning.
Organizational Matrix: Operates in a collaborative, operational partnership locally embedded within the Thailand operation, providing active technical support to local teams while ensuring global engineering governance and regulatory compliance.

Responsibilities

Technical Support & Implementation

Design Implementation: Support the execution of established plant capital projects, including technical equipment setup, system design coordination, and engineering schedule tracking based on approved designs.
Technology & Process Expert: Act as the onsite technical point of contact for new manufacturing equipment, automation setups, and industrial process systems to ensure successful field integration.
Design Review: Collaborate with external contract engineering firms and original equipment manufacturers (OEMs) to review and verify detailed engineering drawings (P&IDs, 3D models, layouts) for site readiness and constructability.

Execution, Construction & Field Coordination

Contractor & Vendor Management: Serve as the main technical interface for equipment suppliers, general contractors, and specialized engineering firms to ensure execution strictly aligns with design parameters.
Cross-Functional Alignment: Work alongside cross-functional internal departments—including local Production, Maintenance, Quality, and Safety teams—to safely execute field installations without disrupting local operations.
Commissioning & Startup: Drive mechanical completion, system dry/wet runs, operational training protocols, and final technical project closure.
Supplier Change Management: Proactively address and manage change orders submitted by suppliers.
PMC Coordination: Maintain close and effective coordination with the hired Project Management Consultancy (PMC) company to ensure alignment on project execution and technical standards.

Project Execution & Progress Control

Timeline & Progress Control: Utilize advanced project tracking tools (e.g., MS Project) to ensure engineering milestone dates are rigorously met, mitigating installation delays.
Risk & Change Management: Identify design gaps or execution bottlenecks early, formulating robust technical solutions and managing formal engineering change orders.
