Ultra-Pure Water+ division of Ecolab (former Ovivo Electronics), is a global provider of advanced equipment, technology, and systems to produce ultrapure water (UPW). We are dedicated to innovation, offering energy-efficient and environmentally sustainable solutions to the world’s most challenging water and wastewater issues.

As a Hydraulic Modelling and Simulation Intern, you will develop a dynamic hydraulic model of a water treatment system and connect it to a PLC and SCADA simulation platform for process validation.

Joining Ecolab means being part of a global team of innovative and passionate professionals who are committed to preserving water, our planet's most critical resource. It also means combining our efforts and talents towards a more sustainable future – together.

How You’ll Make an Impact:

· Hydraulic modelling: Develop a representative dynamic model of a water treatment system, including key hydraulic behavior and process constraints.

· Real-time deployment: Prepare the model for real-time or near-real-time execution within the simulation environment.

· PLC and SCADA connectivity: Implement communication interfaces between the hydraulic model, PLC application, and SCADA application.

· Process validation: Use the integrated platform to validate process sequences, operating scenarios, alarms, and control responses.

· Optimization and analysis: Analyze model results and support optimization of simulation performance, stability, and usability.

· Documentation and collaboration: Document model assumptions, interfaces, test scenarios, and results while working with automation and process engineers.

Qualifications:

· You are completing a Bachelor's or Master's degree in automation, industrial computing, electrical engineering, computer science, robotics, or a related field.

· Knowledge of modelling, real-time simulation, optimization, communication protocols, and software programming is expected.

· Experience with hydraulic modelling tools, Python, MATLAB/Simulink, Modelica, OPC UA, or industrial APIs is an advantage.

· You enjoy diversified tasks and hands-on work in technical workshops and on industrial systems.

· You show initiative and creativity, and you are flexible, structured, and able to work independently with guidance from experienced engineers.

· You have strong team-working and communication skills and can collaborate with international departments, suppliers, and customers.
