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.
Must-Have Requirements
- 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.
Good to Have
- 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.
Experience:
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.
