Backend Systems Engineer - IOT/Smart City
Summary
Build backend systems that connect industrial IoT devices to a digital twin platform, handling real-time data ingestion, protocol translation, and integration using OPC-UA, MODBUS, and MQTT.
Role Overview
Join the Software Engineering team on a physical Operations Technology (OT) integration project. You will build and maintain the backend systems that connect OT field devices to the digital twin platform — handling real-time data ingestion, protocol translation, and system integration across industrial communication standards.
Key Responsibilities- Develop and maintain backend services and middleware for OT/IoT data ingestion using OPC-UA, MODBUS, and MQTT protocols.
- Build data pipeline components that normalise, process, and route telemetry from field devices to platform services and 3D visualisation layers.
- Integrate AI coding tools (e.g. Claude, Copilot) into daily development workflows for code generation, unit testing, and validation — this is an expected practice, not optional.
- Write and maintain automated test suites covering protocol adapters, data transformation logic, and integration endpoints.
- Collaborate with frontend Unity engineers and systems architects to define and implement API contracts (REST/WebSocket).
- Participate in code reviews, contribute to technical documentation, and support deployment through CI/CD pipelines.
- Troubleshoot field connectivity and protocol issues; work with OT/hardware teams on device commissioning and debugging.
- Hands‑on experience with OPC-UA, MODBUS, and MQTT — protocol implementation, not just conceptual familiarity.
- Proficiency in backend development (Python, Node.js, Go, or Java — at least one).
- Active use of AI tools for coding, testing, and validation in prior roles or personal projects.
- Experience writing integration and unit tests; familiarity with test automation frameworks.
- Comfortable working with message brokers (MQTT brokers, Kafka, or similar) and time‑series or event‑driven data.
- Exposure to digital twin platforms or industrial IoT stacks.
- Familiarity with OT security considerations (network segmentation, secure protocol configuration).
- Experience with containerisation (Docker/Kubernetes) and CI/CD tooling.
- Knowledge of BACnet, DNP3, or other industrial protocols.
- 2–5 years in backend or systems software engineering, with at least some exposure to OT/IoT environments.
- Degree in Computer Science, Engineering, or equivalent practical experience.
