The Process Engineer plays a critical leadership role in the expansion of a growing manufacturing facility. This position serves as the primary technical and operational liaison between project teams and plant operations during the introduction of a new major production asset, and then transitions into full process ownership once operational.

This role offers a unique opportunity to be deeply involved in capital expansion, equipment startup, and long‑term operational excellence, while also developing broad plant expertise across existing assets. The successful candidate will help shape the future of the facility by driving safe, efficient, and world‑class manufacturing performance.

This position owns the technical success of a major manufacturing asset with significant business impact. From construction through steady‑state operation, the Process Engineer ensures that processes are built correctly, operated efficiently, and continuously optimized to meet performance, quality, safety, and cost targets.

The role is ideal for an engineer who thrives at the intersection of project execution, plant operations, and continuous improvement, and who wants exposure to end‑to‑end asset ownership in an expanding facility.

• Serve as the on‑site plant point of contact for all activities related to a new production asset during construction, installation, and startup.
• Provide technical leadership and plant integration support to ensure seamless transition from project execution to operations.
• Support equipment commissioning, startup readiness, and operational validation.
• Partner with internal and external stakeholders to resolve technical issues and ensure alignment with plant standards.

• Act as process owner once the asset is operational, accountable for achieving output, quality, material usage, energy efficiency, and safety targets.
• Establish and maintain robust systems for data collection, auditing, and preventive process control.
• Define and manage process setpoints for all product types and develop associated operational tools (SOPs, setup sheets, management systems).
• Lead root‑cause analysis using structured problem‑solving methodologies (RCCA, 5‑Why, Six Sigma‑based tools) and drive corrective and preventive actions.

• Identify and lead process efficiency, quality, and cost‑of‑poor‑quality improvement initiatives.
• Evaluate and implement new technologies to enhance current and future processes.
• Develop and refine process models in collaboration with technical specialists to optimize operational performance.
• Regularly review and optimize raw material specifications based on performance data.

• Train operators, engineers, and technicians on new equipment, processes, and documentation.
