Operations technician
Summary
Field technician installs, maintains, and troubleshoots Hydroleap’s electrocoagulation and electrooxidation water-treatment systems on customer sites across Singapore.
About Hydroleap
Hydroleap is a Singapore-based clean technology company reinventing how industrial wastewater is treated. Instead of relying on heavy chemical dosing, our electrocoagulation (HL-EC) and electrooxidation (HL-EO) systems use electricity to remove contaminants — cutting chemical use, sludge volumes, and operating costs while enabling customers to reuse far more of their water.
Our systems are deployed across data centres, cooling towers, pharmaceutical and semiconductor plants, agrifood facilities and construction sites. Backed by investors such as Real Tech Holdings, Mitsubishi Electric, Wavemaker Partners and Seeds Capital, we are scaling rapidly across Singapore and the wider Asia-Pacific.
As we grow, our field operations team is what keeps these systems performing for customers every day — and that's where you come in.
About the Role
As an Operations Technician, you'll be responsible for the day-to-day operation, maintenance, and troubleshooting of Hydroleap's water/wastewater treatment equipment on-site. You'll work hands-on with mechanical and electrical systems, support plant operations, and help ensure our equipment runs smoothly for our clients. This role is ideal for someone who enjoys hands-on technical work, takes ownership of equipment reliability, and is comfortable working independently in the field.
