Working closely with the Proposal, Sales, and Project Execution teams, the Process Design Engineer ensures that process designs are technically sound, cost-effective, and tailored to client needs across all project phases — from concept to commissioning.

This role combines deep process engineering expertise with cross-functional collaboration, ensuring that each design reflects Waterleau’s technological excellence and commitment to a cleaner environment.

Responsibilities

Process Design & Development

• Develop and optimize biological, chemical, and physical wastewater treatment desings, including activated sludge, MBR, MBBR, tertiary treatment, sludge digestion, and dewatering.
• Prepare and validate heat and mass balances, process design calculations, and process flow diagrams (P&Ids and PFDs).
• Define and size key process units (reactors, clarifiers, pumps, blowers, filters, etc.) and ensure compliance with internal design standards.

Engineering Deliverables & Documentation

• Produce and review P&IDs, datasheets, and design specifications for process equipment.
• Prepare process design notes, ensuring technical clarity and alignment with project requirements.
• Contribute to interdisciplinary design reviews, providing input to mechanical, electrical, civil, and control teams.
• Ensure design consistency across all project documents and adherence to Waterleau’s quality standards.

Project & Proposal Support

• Provide technical input during proposal and tender phases, validating process assumptions and ensuring cost-effectiveness.
• Collaborate with the Proposal and Sales teams to develop competitive and technically feasible solutions.
• Support project execution teams during nasic engineer and detailed design.

Process Validation & Innovation

• Ensure that all process calculations and simulations follow internal design rules and are properly validated.
• Contribute to continuous improvement by identifying opportunities to enhance efficiency, sustainability, and standardization.
• Stay up to date with emerging technologies and integrate innovative solutions such as resource recovery, energy-neutral operations, and circular water reuse.
