RSK CFSE PTE. LTD. Hiring! Full Time Field Engineer – IoT - RF Communications in , Earn up to SGD 4,500 - Ricebowl

The Field Engineer is responsible for identifying, investigating, and resolving operational issues associated with IoT network equipment and sensors, with a strong focus on radio frequency (RF) communications and mesh network performance . This role bridges back-office systems and field deployment, ensuring reliable device communication, robust wireless connectivity, and successful implementation of smart metering and smart grid initiatives.

Key Responsibilities:

• Investigate operational issues by performing system checks and validations to determine whether field diagnosis is required.
• Conduct on-site investigations of radio communication equipment and sensors to perform root cause analysis and implement corrective actions.
• Provide on-site technical assistance to troubleshoot and resolve any issues on RF equipment, communication interfaces, and software applications.
• Create work orders and service tickets to ensure remedial works are completed within service levels.
• Escalate recurring RF or network issues for deeper engineering analysis.
• Support deployment of IoT communication infrastructure including collectors, repeaters, antennas, and access points.
• Conduct RF site surveys (RSSI, SINR, coverage mapping) and optimise antenna placement and network topology.
• Commission, register, and test new communication devices, ensuring successful integration into the IoT platform.
• Carry out field testing of RF technologies.
• Maintain technical documentation, field procedures, and troubleshooting guides.

Technical Expertise:

• RF Communications: Strong understanding of RF propagation, antenna theory, RSSI/SINR measurement, and interference mitigation.
• Mesh Networking: Hands-on experience with multi-hop, self-healing RF mesh networks, including node commissioning, routing, and optimisation.
• Standards & Protocols: Familiarity with Wi-SUN or similar open standards for utility mesh networks.
• Routing in Low-Power Networks: Understanding of routing protocols for constrained, lossy networks (e.g. RPL, LOADng).
• Test Equipment: Proficiency with spectrum analysers, network analysers, RF scanners, and signal generators.
• Network Integration: Exposure to multi-tier network architectures).
• Diagnostics: Experience with network health tools (node counters, retransmission rates, hop counts) and identifying systemic issues.
• Utility Technology: Familiarity with smart meters, MIUs, and utility communication modules are a bonus.

Professional Skills:

• Strong analytical and troubleshooting skills, especially for RF and mesh network issues.
• Effective communication with both technical and non-technical stakeholders.
• Ability to document findings clearly and produce accurate technical reports.
• Demonstrated adaptability and capacity to learn new technologies quickly.
