Job Description

Decarb Engineering & Construction Pte Ltd is a Singapore-based M&E EPC contractor specialising in Fire Protection, ACMV, and ELV systems, holding bizSAFE Star and ISO 9001/14001/45001 certifications. We are seeking a Mechanical Engineer to lead the design, engineering, and delivery of water-based and special hazards fire protection systems — including clean agent gas suppression, across commercial, industrial, data centre, and process facility projects.

Roles & Responsibilities

• Design and engineer fire protection systems: wet/dry riser, sprinkler, hose reel, hydrant, fire pump, and water storage systems.
• Lead design and delivery of special hazards systems — clean agent gaseous suppression (FM-200/HFC-227ea, Novec 1230/FK-5-1-12, inert gas/IG-541/IG-55), CO₂ systems, water mist, and aerosol/condensed aerosol suppression.
• Perform hydraulic calculations, enclosure integrity assessment, and clean agent concentration/quantity design calculations to NFPA 2001 / ISO 14520.
• Prepare design drawings, schematics, BOQs, technical submittals, and method statements for consultant and SCDF/authority approval.
• Conduct system sizing, equipment selection, and vendor/OEM coordination (e.g. cylinder banks, nozzles, detection-actuation interface).
• Oversee installation, testing, and commissioning — including room integrity (door fan) testing and discharge testing where applicable.
• Coordinate the detection-and-release interface between gas suppression and fire alarm systems.
• Ensure full compliance with SS CP 52, SS 575, SS 578, NFPA 13/14/20/2001/12/750, and SCDF requirements.
• Liaise with clients, consultants, main contractors, and authorities through design, submission, delivery, and handover.
• Provide site technical support, fault diagnosis, and resolution during execution and defects-liability periods.

Requirements

• Degree or Diploma in Mechanical Engineering or related discipline.
• 3–6 years' experience in fire protection design/engineering within the M&E or building/construction industry.
• Demonstrated experience with clean agent / gaseous suppression and special hazards systems.
• Proficiency in hydraulic calculation software (e.g. HydraCAD, Pipenet, AutoSPRINK) and AutoCAD.
• Working knowledge of Singapore fire codes (SS CP 52, SS 575, SS 578) and NFPA standards (13/14/20/2001).
• Familiarity with SCDF submission and approval processes (Qualified Person coordination, FSSD requirements).
• Strong calculation, technical documentation, and problem-solving skills.
• Experience in data centre, semiconductor, or process/industrial facilities an advantage.
• Valid Class 3 driving licence a plus.
• Good communication and coordination skills for multi-disciplinary project delivery.
