Network Engineer (IoT) - 18 months Contract

Contract Period: 18 Months Working Location: Central / 2 days WFH Role Overview  We are seeking an experienced Network Engineer with strong IoT and telemetry systems expertise to support the design and implementation of a technology platform. The role will focus on field device connectivity, open-standard data protocols, edge communications, and reliable data transmission from environmental sensors and data loggers into a central ingestion platform.  The ideal candidate has hands-on experience working across the full telemetry lifecycle, from sensor and data logger integration to operational device monitoring, buffering, and bidirectional communication with cloud or central data systems.  Key Responsibilities  • Serve as a technical lead for IoT connectivity, telemetry integration, and field-to-platform communication design.  • Design and implement communication flows between automatic weather stations, data loggers, and the central ingestion platform.  • Work with environmental telemetry equipment, commercial data loggers, and equivalent field instrumentation systems.  • Develop integrations using open-standard IoT protocols such as MQTT or equivalent messaging protocols.  • Implement edge-side data buffering and retry strategies to handle intermittent cellular or field network connectivity.  • Support device state monitoring, sensor inventory tracking, calibration offset handling, and operational management workflows.  • Perform low-level data manipulation, including byte stream parsing, bitwise operations, and Big-Endian/Little-Endian data handling.  • Collaborate with data engineers, service designers, field technicians, and project stakeholders to validate end-to-end system behaviour.  • Contribute to technical documentation, integration specifications, and operational handover materials.  Required Skills and Experience  • Strong experience designing or implementing IoT, telemetry, SCADA-adjacent, or sensor data communication systems.  • Hands-on experience with data logger integration and environmental sensor platforms.  • Proficiency in scripting or programming for device communication, data parsing, and protocol handling.  • Practical experience with MQTT or comparable IoT communication protocols.  • Good understanding of cellular network reliability issues, offline buffering, retries, and edge connectivity patterns.  • Ability to troubleshoot field-to-cloud data flows across hardware, network, protocol, and application layers.  • Strong technical communication skills and ability to work with both engineering and operational teams.  Good to Have  • Experience with meteorological, environmental monitoring, utilities, transport, industrial IoT, or mission-critical operational systems.  • Familiarity with time-series data ingestion, device health monitoring, and calibration workflows.  • Experience contributing to early-stage platform builds that later transition into production-grade platforms.
