• Coordinate with Laboratory and Operations on sampling protocols, analytical accuracy, and pilot/benchtest validation.
• Collaborate with DCS and Controls Engineering to review and update control logic, participate in HAZOPs,PHAs, and ensure interlocks and safety systems are current.
• Provide hands-on troubleshooting for critical plant disruptions and support operational stabilization andreliability.

2.Process review and optimization

• Oversee the development and continuous improvement of process monitoring tools (e.g. PI Datalink,DataParc, PCS7, LIMS (Laboratory Information Management System), downtime tracking) for lime andslurry operations.
• Standardize and review daily control room plans and alarm management to ensure optimal operationalresponse and system stability.
• Conduct material and energy balances, efficiency calculations, and root cause investigations to identifyimprovement opportunities across milling, crushing, calcining, and ancillary systems.
• Issue formal technical memoranda and troubleshooting guides; lead structured plant audits andperformance reviews.

3.Project support and implementation 

• Act as the primary technical custodian for the Management of Change (MOC) process for bulk commodityoperations.
• Identify, prioritize, and support the implementation of plant modifications or projects aimed atperformance improvement or risk mitigation.
• Provide technical guidance to project teams to ensure alignment with operational priorities andequipment integrity standards.
• 
  

4.Coaching and training

• Mentor Process Engineers & control room supervisor on technical career progression, performanceexpectations, and best engineering practices.
• Deliver structured training programs and coaching for Supervisors, Control Room Operators, and FieldOperators, particularly in areas of milling, slaking, and calcining.
• Strengthen operational competency at all levels through daily engagement, process walkthroughs, andpractical upskilling.
• Develop, implement, and maintain standardized operating procedures (SOPs) and training materials

•  over 8–10 years of hands-on experience in continuous process industries, the candidate brings deep operational and technical expertise in bulk solids handling, pyroprocessing, and hydrometallurgical systems, particularly in lime, cement, and mineral processing operations.

• Wet milling operations: closed-loop ball mill systems, density control, cyclone classification, and lime slaking via vertical mills.
• Crushing and screening: operation of impact crushers, double-roll crushers, and vibrating screens.
• Calcination systems: rotary kilns and preheaters, including combustion control and lime quality management.
• Ancillary systems: mechanical conveying, lime storage & aeration, dust collection.

• Execution of mass/energy balances, throughput modeling, and efficiency analysis across comminution circuits.
• Advanced troubleshooting and RCA leadership to restore stability under upset conditions.
• Experience in technical change management processes (HAZOP, PHA, MOC).

• Proficient in Siemens PCS7, PI Datalink, DataParc platforms.
• Skilled in process loop tuning and diagnostics of key instrumentation (flow, pressure, control valves, etc.).

• Developed and delivered SOPs and training modules for operators and engineers using simulators and plant walkdowns.
• Strong written and verbal communication in French, with proficient English for international collaboration.

• Prior roles in lime, cement, and related heavy industrial sectors (pyroprocessing, kiln systems) offer a direct advantage for similar environments.
