Unity 3D Frontend Engineer - Contract - Part-Time

ROLE OVERVIEW

We are looking for a Senior Unity 3D Frontend Engineer to lead the design and development of cutting-edge interactive 3D visualisation interfaces. You will play a pivotal role in delivering real-time digital twin dashboards, operational technology (OT) views, and geospatial systems that power smart city, industrial, and operational environments.

This role bridges advanced frontend engineering with deep IoT/OT integration expertise, working alongside robotics, IoT, and OT engineering teams to translate live sensor and telemetry data into compelling real-time 3D experiences.

KEY RESPONSIBILITIES

1.3D Visualisation & Interface Development

• Lead the design and development of interactive 3D visualisation interfaces using Unity 3D, including real-time digital twin dashboards and OT operational views.

• Drive technical decisions around rendering performance, level-of-detail (LOD) strategies, shader optimisation, and scene management for large-scale operational environments.

• Build and maintain reusable UI component libraries within Unity, aligned to UX guidelines and design system standards.

2. Geospatial Systems

• Architect and implement geospatial rendering systems — integrating map layers, coordinate systems, and spatial data into Unity-based frontends.

3. Systems Integration & Data Pipelines

• Design and deliver seamless integration between Unity frontend components and backend systems, middleware, IoT/OT data pipelines, and REST/WebSocket APIs.

• Collaborate with IoT, OT, and robotics engineering teams to translate telemetry, sensor, and asset data into real-time 3D visualisation.

4. Engineering Leadership & Standards

• Define and enforce frontend engineering standards, coding conventions, and review practices.

• Engage with product owners, systems architects, and client stakeholders to ensure frontend solutions meet functional and non-functional requirements.

• Contribute to CI/CD pipeline integration for build artefacts, automated testing, and deployment workflows.

EXPERIENCE & QUALIFICATIONS

1. Core Engineering Experience

• Minimum 5 years of software engineering experience, with at least 3 years focused on Unity 3D development in a production environment.

• Demonstrated delivery of Digital Twin or 3D visualisation solutions for operational, industrial, or smart city domains.

• Track record as a subject matter expert — driving architecture decisions, conducting code reviews, and managing delivery risk.

• Strong understanding of systems engineering principles; able to design frontend components with awareness of full-stack integration constraints.

2. IoT / OT & Integration Knowledge

• Understanding of IoT integrations such as OPC-UA, Modbus, and MQTT.

• Experience with middleware integration and Building Management System (BMS) integration.

• Hands-on experience integrating real-time IoT/OT sensor data into interactive 3D or geospatial frontends.

• Understanding of Command and Control (C3) systems.

3. Education & Mindset

• Bachelor's degree or higher in Computer Science, Software Engineering, Geospatial Science, or equivalent discipline.

• Comfort using AI to accelerate coding, testing, and validation is a must.
