Job Description

Position Overview

We are seeking a highly experienced Senior Resource for our Water Systems Engineering Team. The ideal candidate must haveat least 10,000 hours of focused, hands-on experiencein the development, design, and commissioning of water filtration systems. The role requires a professional who has independently worked onpump selection, membrane sizing, filtration architecture, and complete system engineering forindustrial water treatment, wastewater treatment, and drinking-water purification plants.

The selected candidate will play a central role in designing and building our3 MLD advanced water filtration systemfor theXPRIZE Water Solutions Challenge. This is a senior-level engineering position requiring strong analytical abilities, deep domain knowledge in membrane science and filtration processes, and proven experience in working with multidisciplinary teams.

Key Responsibilities

1. System Design and Engineering

• Lead the complete design of a 3 MLD (Million Liters per Day)water filtration system, including pre-treatment, membrane modules, pump architecture, hydraulics, and polishing stages.
• Develop detailed system block diagrams, P&IDs, mass-balance calculations, hydraulic flow distribution models, and energy-use calculations.
• Perform quick, accurate engineering calculations using fundamental equations such as:

Darcy’s Lawfor membrane permeability

• Evaluate filtration limitations, membrane fouling points, flux decline, recovery ratios, and cleaning requirements.

2. Membrane Technology and Formulations

• Work with membrane scientists to evaluate and developnew membrane formulations, including hollow-fiber, spiral-wound, nano filtration, RO, and UF membranes.
• Select suitable membrane materials based on feed characteristics, fouling potential, water chemistry, and target output.
• Define operating windows, cleaning protocols, and long-term performance characteristics.

3. Pump Selection and Hydraulics

• Select high-efficiency pumps for raw-water intake, high-pressure reverse-osmosis, permeate pumping, recirculation systems, and chemical dosing.
• Size pumps based on TDH, suction head, NPSH, viscosity, salt concentration, and fouling factors.
• Optimize pump stages to reduce energy consumption for a 3 MLD system.

4. System Integration and Prototyping

• Work hands‑on with mechanical, electrical, controls, and materials teams to build prototypes and iterate rapidly.
• Develop testing protocols for flow, pressure, fouling rate, recovery, and membrane integrity.
• Troubleshoot issues such as pressure imbalances, scaling, bio‑fouling, pump cavitation, or fouling‑induced flux decline.

5. Cross-Functional Team Collaboration

• Coordinate with process engineers, electrical engineers, membrane developers, chemists, and fabrication teams.
• Translate design concepts into manufacturability systems.
• Mentor junior team members and guide them in calculations, design logic, and engineering fundamentals.

6. XPRIZE Water Challenge Deliverables

• Oversee all engineering efforts for our XPRIZE submission.
• Prepare system documentation, performance data, energy‑efficiency reports, and life-cycle analyses.
• Ensure the 3 MLD system meets XPRIZE scoring criteria on efficiency, cost, reliability, and impact.
