Jobbeschreibung

Senior Field Engineer (Based in Klang Valley & Johor)

Is a high-level technical expert responsible for the hands-on (i) commissioning, (ii) troubleshooting, and (iii) optimization of complex industrial water treatment plants.

Unlike entry-level engineers, a senior engineer serves as the primary technical authority on-site, mentors junior staff, and solves the most critical systemic failures.

Job Summary

The Senior Field Engineer acts as the technical anchor during plant startups, major overhauls, and emergency system failures. Operating at the intersection of process chemistry, HVAC and mechanical systems, electrical and control system

You will ensure systems filtration systems and water treatment plants/systems meet stringent design specs and regulatory compliance.

Core Responsibilities

Advanced Troubleshooting & Process Optimization

Diagnose complex process deviations, mechanical failures, and electrical and control system anomalies that standard field technicians cannot resolve.

Optimize plant chemistry and operating parameters (e.g., anti-scale/corrosion dosing, micro-organism control, chemical configurations, etc.) to extend water system lifespans and reduce operating costs.

Lead emergency root-cause analysis (RCA) for major system upsets, implementing immediate corrective actions to minimize client plant downtime.

Commissioning & Plant Start-Ups

Direct the pre-commissioning and commissioning phases of newly installed water treatment systems.

Perform loop testing, instrument calibration, and control system functional checks alongside automation teams.

Execute formal plant handovers, verifying that treated water quality strictly meets client requirements and contractual obligations.

Provide technical consulting to clients, recommending system retrofits, upgrades, or chemical program changes.

Collaborate with design and sales engineering teams to feedback real-world performance data, helping refine future equipment blueprints.

Author comprehensive engineering reports, detailing site audits, performance logs, and recommended mechanical improvements.

Mentorship & Safety Leadership

Train and mentor junior field engineers, site operators, and technicians on advanced diagnostics and safe operating practices.

Champion high-risk safety protocols, ensuring all site activities strictly conform to OSHA, confined space entry, etc.

Required Skills & Qualifications

Category/Requirements

Education

Bachelor’s Degree in Chemical, Environmental, or Mechanical Engineering.

Experience

4+ years of direct field engineering experience in industrial water treatment, with a proven track record of leading large-scale system commissioning.

Technical Expertise

Mastery of advanced filtration systems, HVAC and heat exchange processes, biological treatments, chemical properties and their applications, and instrumentation (sensors, control valves, VFDs).

Automation Skills

Strong proficiency in reading control and electrical schematics, with basic competency in modifying or troubleshooting PLC logic.

Soft Skills

Decisive leadership under pressure, high-level analytical problem solving, and the ability to articulate complex technical jargon to non-technical clients.

Logistics

Valid driver's license and flexibility to travel to client sites and ability to travel and adapt to demanding site environments.
