“Build, what matters. Grow, without limits. Power, the future with Hanwha Ocean EPU.”

Position Overview

The Lead Process Engineer leads and governs process design basis, PFD/P&ID development, heat and material balance, process simulation inputs, equipment process datasheets, safety review inputs, and start-up/commissioning process support for FPSO, FLNG, fixed platform, offshore renewable, onshore power, petrochemical, LNG, hydrogen/ammonia, CCS, and other complex plant projects. This role contributes to safe, constructible, compliant, and cost-effective project delivery by defining technical requirements, verifying calculations/specifications, resolving technical queries, and safeguarding design integrity.

The position works in a multidisciplinary FEED/EPCI environment with engineering, procurement, vendors, fabrication yards, construction, commissioning, and project management teams. The role manages discipline scope, model/deliverable schedule, resource priorities, client and subcontractor interfaces, review close-out, and progress/risk reporting for assigned project areas.

The position supports safe, operable, and efficient plant design by integrating process requirements with equipment, piping, safety, control, and commissioning considerations across concept, FEED, detailed engineering, and execution phases. It is expected to maintain technical consistency across calculations, simulations, data sheets, process diagrams, and design interfaces while supporting project teams in managing performance, risk, and change.

At this level, the role provides day-to-day leadership for assigned scopes, coordinates resources and interfaces, reviews deliverables, and ensures that work is executed in line with schedule, quality, and technical expectations. The position is expected to guide more junior team members, proactively address risks, and maintain alignment between discipline work, project priorities, and stakeholder requirements.

Key Responsibility

• Lead and coordinate process design basis, PFD/P&ID development, heat and material balance, process simulation inputs, equipment process datasheets, safety review inputs, and start-up/commissioning process support in accordance with project specifications, client requirements, class/regulatory expectations, international codes, and company standards.
• Prepare, update, check, or coordinate design basis documents, PFDs, P&IDs, HMBs, process simulations, equipment process datasheets, cause-and-effect inputs, HAZOP actions, and commissioning/start-up support notes, ensuring accuracy, revision traceability, constructability, and timely issue for project milestones.
• Define or verify technical requirements, calculations, design basis assumptions, specifications, technical requisitions, vendor document comments, and technical query responses within the assigned discipline.
• Coordinate interfaces with process, mechanical, piping, electrical, instrumentation, structural, safety, procurement, construction, commissioning, vendors, subcontractors, and fabrication yards to close interdisciplinary issues.
• Support 30% / 60% / 90% design reviews, model reviews, layout reviews, constructability reviews, HAZOP/HAZID inputs where relevant, and client/vendor comment close-out.
• Identify constructability concerns, interface gaps, material or vendor data risks, schedule impacts, and management-of-change items; communicate mitigation actions clearly.
• Maintain engineering records, drawing/model data, review comments, calculations or registers, and as-built information in accordance with document control and quality procedures.
• Manage assigned scope, manpower priorities, deliverable schedule, subcontractor interfaces, progress reporting, and recovery actions for late or high-risk deliverables.

Qualification

• Minimum: Bachelor’s degree in Chemical Engineering, Process Engineering, or a related engineering discipline. Preferred: Master’s degree for Principal/Lead roles or complex process technology assignments.
