Senior Process Engineer (RO Plants & Water Treatment Systems)

■ Design Engineering

Lead the overall process design of RO plants, covering intake, pretreatment, RO systems (BWRO / SWRO), and post-treatment.

Prepare technical documentation, including Process Flow Diagrams (PFD), Piping and Instrumentation Diagrams (P&ID), specifications, and calculation sheets.

Select appropriate RO membranes and design pretreatment processes such as UF (Ultrafiltration) and MF (Microfiltration).

Design and evaluate water quality balance across the entire plant.

(Preferred) Experience in designing and implementing water reuse systems using treated wastewater as RO feedwater.

■ Project Management

Manage design schedules and monitor progress.

Coordinate with domestic and international engineering partners.

Collaborate with internal departments for technical alignment and integration.

Conduct design reviews and ensure quality control.

Engage in technical discussions with clients, gather requirements, and propose Value Engineering (VE) solutions.

■ Technical Sales Support

Support technical planning and process selection during proposal stages.

Prepare technical sections of bid documents.

Provide technical presentations and respond to client inquiries.

Optimize process proposals based on cost and schedule considerations.

Note : Technical sales responsibilities will be assigned based on the candidate’s aptitude and experience.

We are looking for a senior process engineer to join our design / engineering team. Work experience : 10+ years, the more the better.

The candidate should have extensive design experience for large-scale RO (more than 5MLD as permeate).

We are not looking for a site person or a construction person.

They should be comfortable managing the design work for the full process.

• Intake
• Pretreatment
• Main BWRO and SWRO
• Post Treatment

Ideally, we would like someone familiar with reuse water system design (using the treated effluent of a sewage treatment plant as the feed for the RO plant).

But it is nice to have, rather than a hard requirement.

Benefits :

HMO, 13th month, SL / VL, others

Work schedule : Monday to Friday 8 : 00~17 : 00

Interview process : 2~3 times
