• Lead the development of technically and commercially optimized treatment solutions for water, wastewater, and industrial wastewater applications.
• Evaluate raw water, wastewater, effluent, and product water requirements, proposing practical and effective solutions to complex treatment challenges.
• Establish design criteria, process guarantees, design margins, technology selection, and overall process philosophy.
• Perform detailed process design during proposal preparation and engineering stages.

1. 2. Process Design, Calculations & Simulation

• Prepare, review, validate, and approve manual process design calculations, mass balances, hydraulic profiles, equipment sizing, PFDs, P&IDs, control narratives, and process datasheets.
• Perform and review biological process simulations, primarily using BioWin, as well as membrane projections for brackish water RO, seawater RO, ultrafiltration, EDI, and related systems.
• Verify consistency between manual calculations, software outputs, vendor selections, and contractual performance requirements.

1. 3. Team Management & Deliverable Control

• Plan, assign, monitor, and review the work of process engineers and drafting personnel.
• Ensure the quality, accuracy, traceability, and timely issuance of process deliverables in accordance with the engineering schedule.
• Mentor and develop the process engineering team, enhance technical capabilities, and standardize calculation methods, templates, and design practices.

1. 4. Equipment Selection & Multidisciplinary Coordination

• Select, size, and specify process equipment, including pumps, air blowers, fans, pressure and process vessels, safety valves, control valves, orifices, cooling towers, absorbers, strippers, disc filters, and sludge dewatering equipment.
• Coordinate process requirements and technical interfaces with mechanical, piping, civil, structural, electrical, instrumentation, automation, proposal, procurement, construction, and commissioning teams.

1. 5. Client, Vendor, Risk & Performance Management

• Lead technical meetings, design reviews, value engineering exercises, and HAZOP/HAZID activities.
• Manage technical clarifications and coordination with clients, consultants, authorities, vendors, and technology providers.
• Review vendor proposals, technical submissions, and process guarantees.
• Identify and manage technical risks, support commissioning and troubleshooting activities, and verify plant performance against approved design requirements.

Necessary Knowledge and Experience:

• Minimum 15 years of experience in process engineering and design for water, wastewater, and industrial wastewater treatment projects, including substantial experience in process leadership or management roles.
• Proven experience in leading process engineering teams, managing multidisciplinary project interfaces, and overseeing process engineering activities throughout the project lifecycle.
• Extensive technical knowledge of water treatment processes, including brackish water RO, seawater RO, softening, de-aeration, gas stripping, adsorption, media filtration, ultrafiltration, high-purity water treatment, EDI, disinfection, and remineralization.
• Extensive technical knowledge of wastewater treatment processes, including conventional activated sludge, MBBR, MBR, SBR, trickling filters, odor control systems, anaerobic digestion, industrial wastewater treatment, tertiary treatment, sludge handling, and sludge dewatering.
• Expertise in process equipment selection, sizing, specification, and technical evaluation, including pumps, air blowers, fans, control valves, pressure and process vessels, safety valves, orifices, cooling towers, absorbers, strippers, disc filters, and sludge dewatering equipment.
• Ability to independently prepare, review, and validate manual process design calculations, including mass balances, hydraulic profiles, biological treatment, membrane systems, chemical dosing, air demand, sludge production, equipment capacity, and utility consumption.
• Hands-on experience in process simulation and projection software, primarily BioWin and recognized RO projection tools. Experience with additional water and wastewater modelling software is an advantage.
• Ability to diagnose process and treatment performance issues and develop practical, reliable, and cost-effective solutions for complex water, wastewater, and industrial wastewater challenges.
• Extensive experience across all project stages, including conceptual design, proposal preparation, FEED/basic engineering, detailed engineering, vendor technical reviews, commissioning support, troubleshooting, and plant performance evaluation.
• Strong knowledge of process guarantees, design margins, process operability, maintainability, energy optimization, lifecycle costing, process safety, and applicable international standards and local regulatory requirements.
