Engineer, ICOMMS

Key Responsibilities

Plan, design, and implement Distributed Antenna System (DAS), BTS, Remote Units (RUs), fibre optic networks, RF feeders, antennas, splitters, couplers, and passive RF components.

Prepare engineering documents including system design, method statements, installation drawings, RF calculations, testing procedures, and as-built documentation.

Coordinate with Mobile Network Operators on system integration, acceptance testing, and commissioning activities.

Conduct RF site surveys, coverage analysis, drive tests, walk tests, and troubleshooting using industry-standard tools.

Analyse KPIs such as RSRP, RSRQ, SINR, throughput, call setup success rate, handover success rate, ERAB success rate, and interference levels.

Investigate RF issues including Passive Intermodulation (PIM), interference, VSWR, feeder losses, fibre attenuation, and hardware faults.

Support Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), Acceptance Test Procedures (ATP), and Integrated System Testing (IST).

Coordinate night engineering works during MRT engineering hours, ensuring compliance with track access procedures and railway safety regulations.

Liaise with civil, electrical, signalling, and rail operation teams to coordinate installation activities and project interfaces.

Supervise subcontractors to ensure installation quality, workmanship, and compliance with project specifications.

Monitor project progress and prepare technical reports, progress updates, risk assessments, and engineering documentation.

Ensure all works comply with Authority requirements, workplace safety regulations, and project quality management systems.

Support fault investigations and emergency restoration activities when required.
