Junior Digital Twin Engineer

Title: Junior Digital Twin Engineer (Fresh Graduate)

Team: Surbana Technologies Pte. Ltd.

Role Overview

As a Junior Digital Twin Engineer, you will contribute to the design, development, and deployment of intelligent Digital Twin solutions for smart buildings and infrastructure. You will work closely with engineers, designers, and domain experts to build real-time, data-driven 3D environments that bridge the physical and digital worlds.

Digital Twins are dynamic, data-rich models that integrate real-time sensor data, simulations, and analytics to monitor, predict, and optimize real-world systems across their lifecycle. This role provides hands-on experience across the full Digital Twin stack—from visualization to IoT integration and intelligent automation.

Key Responsibilities

1. Digital Twin Development (3D & Applications)

• Develop and maintain Digital Twin applications using Unity (primary) and explore other technologies such as Unreal Engine and Three.js where required

• Implement interactive and responsive user interfaces (e.g., Unity UI Toolkit)

• Integrate real-time data into 3D environments for visualization and control of smart building systems

2. System Integration, Data Pipelines & Real-Time Communication

• Integrate Digital Twin applications with backend systems, APIs, and databases to support real-time data flow between physical and digital systems

• Work with IoT data streams and implement real-time communication using messaging systems (e.g., NATS) and protocols such as WebSocket for live updates

• Assist in debugging and maintaining data pipelines, ensuring reliable data synchronization, latency handling, and system stability

3. Deployment & Onsite Support

• Assist in deploying Digital Twin solutions in production environments (e.g., buildings, facilities)

• Support testing, debugging, and optimization of systems under real-world conditions

• Collaborate with stakeholders (e.g., facility managers, engineers) during deployment and handover

5. R&D and Automation

• Conduct research and experimentation to improve:

  • Development workflows

  • Project operations and delivery pipelines

  • Knowledge management systems

• Build automation pipelines using tools such as n8n, scripting, or AI-assisted workflows

• Prototype new capabilities to enhance Digital Twin scalability and performance

What You Will Gain

• Hands-on experience building end-to-end Digital Twin systems (3D + IoT + backend + analytics)

• Exposure to Smart City and Smart Building technologies (BIM, GIS, IoT, AI)

• Real-world deployment experience in production environments

• Opportunity to work with multidisciplinary experts across engineering, construction, and operations

Career Growth & Learning Opportunities

You will gain exposure to the full maturity spectrum of Digital Twins, which evolve across five levels of capability:

• Descriptive Twins – 3D visual models and centralized data

• Informative Twins – Integration of real-time IoT and operational data

• Predictive Twins – Analytics and forecasting insights

• Comprehensive Twins – Simulation and “what-if” scenario modelling

• Autonomous Twins – AI-driven systems capable of decision-making and automation

Requirements

• A degree in Computer Science, Software Engineering, or related field

• Familiarity with one or more programming languages (C#, JavaScript, Python, etc.)

• Basic understanding of software engineering principles and problem-solving skills

• Interest in one or more of the following:

  • Real-time 3D (Unity, Unreal, WebGL)

  • IoT systems and data integration

  • AI, computer vision, or data analytics

• Strong willingness to learn and adapt in a fast-evolving technology space

Good to Have

• Experience with Unity or other 3D engines

• Exposure to REST APIs, backend systems, or cloud platforms

• Familiarity with BIM/GIS concepts or tools

• Interest in workflow automation (e.g., n8n, scripting, AI tools)

Why This Role is Different

Unlike a typical junior software engineer role, this position blends:

• Real-time 3D development

• Systems engineering (IoT + backend)

• Data + AI

• R&D and automation

You won’t just build features—you’ll help shape how Digital Twin systems are built and deployed.
