Full Time SENIOR ENGINEER Jobs, Salary up to SGD 6,000 in UK ENGINEERING CONSULTANCY PTE. LTD. Islandwide (Singapore) - Maukerja

Lead design and engineering of UPW generation and distribution systems for semiconductor fabs.• Develop process design basis, PFDs, P&IDs, hydraulic calculations, and specifications.• Oversee design of pretreatment (RO/UF), primary purification (EDI/IX), and polishing systems (UV, mixed bed, membrane degasification).• Define distribution loop design including constant recirculation, velocity control, and dead-leg elimination.• Perform flow, pressure drop, and loop balancing calculations.• Interface with tool engineers to ensure UPW quality requirements are met at point-of-use.• Review vendor design packages and manage EPC contractors.• Drive optimization of water usage and recovery efficiency.
Design multi-stage UPW systems (Pre-treatment → RO → EDI → Polishing Loop).• Ensure high purity standards: Resistivity 18.2 MΩ·cm, TOC < 1 ppb, particles < critical limits.• Control ionic, organic, and microbial contamination.• Develop loop design ensuring continuous recirculation and temperature control.• Implement redundancy (duty/standby trains) for 24/7 operation.Distribution System Design• Design UPW distribution loop with high purity PVDF piping.• Maintain flow velocity (1–2 m/s typical) to prevent stagnation.• Eliminate dead legs and maintain sanitary design practices.• Integrate point-of-use filters, UV oxidation, and TOC monitoring.• Ensure pressure stability at tool interface.
