About the Engagement

We are seeking a talented Backend Software Engineer to join the Software Engineering team on a Smart City initiative. You will play a hands-on role in the systems engineering of a data platform that integrates IT and OT devices — bridging field hardware with digital services in a live operational environment.

Role Overview

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. This is a delivery-focused engineering role; you will be expected to ship production code, write tests, and actively use AI coding tools as part of your standard workflow.

Key Responsibilities

  • Develop and maintain backend services and middleware for OT/IoT data ingestion, with hands-on implementation across OT protocols (e.g. OPC-UA, MODBUS, and MQTT).
  • 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, GitHub 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).
  • Support deployment through CI/CD pipelines; contribute to technical documentation and code reviews.
  • Troubleshoot field connectivity and protocol issues; work alongside OT/hardware teams on device commissioning and debugging.

Requirements

MUST HAVE

OPC-UA, MODBUS, and MQTT — hands-on protocol implementation experience, not just conceptual familiarity.

MUST HAVE

Backend development proficiency in at least one of: Python, Node.js, Go, or Java.

MUST HAVE

Active use of AI tools (Claude, Copilot, or similar) for coding, testing, and validation in prior roles or personal projects.

MUST HAVE

Experience writing integration and unit tests; familiarity with test automation frameworks.

MUST HAVE

Comfortable working with message brokers (MQTT brokers, Kafka, or similar) and time-series or event-driven data architectures.

GOOD TO HAVE

Exposure to digital twin platforms or industrial IoT stacks.

GOOD TO HAVE

Familiarity with OT security — network segmentation, secure protocol configuration.

GOOD TO HAVE

Experience with containerisation (Docker/Kubernetes) and CI/CD tooling.

GOOD TO HAVE

Knowledge of additional industrial protocols: SCADA, BACnet, DNP3, or similar.

Experience & Qualifications

  • At least 4 years in backend or systems software engineering, with exposure exposure to OT/IoT environments.
  • Degree in Computer Science, Software/Systems Engineering, or equivalent practical experience.
