0–5 years of experience in commissioning, start-up, process engineering or industrial project environments.
A good understanding of process equipment, instrumentation and industrial automation; familiarity with PLC/SCADA systems is an advantage.
The ability to read and interpret P&IDs, electrical schematics and functional descriptions.
A proactive, hands-on mindset with strong analytical and problem-solving skills.
Excellent communication skills and the ability to collaborate in multidisciplinary and international teams.
A customer-focused attitude and the confidence to build strong relationships on-site.
A willingness to travel internationally and work on customer sites for extended periods.
Fluent in English; additional languages are a plus.

Exposure to innovative water treatment projects across the globe.
