Key Responsibilities

• Develop and enhance interactive 3D digital twins for data centers, buildings, industrial facilities, and physical infrastructure.
• Design and implement browser-based 3D applications using Three.js, WebGL, and JavaScript/TypeScript.
• Integrate real-time telemetry, sensor data, asset health, equipment status, and alarms into 3D environments using REST APIs and WebSockets.
• Implement interactive capabilities including navigation, object selection, filtering, highlighting, and asset-level drill-down.
• Import, process, and integrate 3D models from GLTF/GLB, OBJ, FBX, BIM/IFC, and CAD-derived formats.
• Optimize rendering performance, scene complexity, memory utilization, and browser responsiveness.
• Collaborate with product, UI/UX, and backend engineering teams to deliver scalable, production-ready solutions.

Required Skills & Experience

• 3+ years of relevant software engineering or 3D application development experience.
• Strong hands-on expertise in Three.js, WebGL, JavaScript/TypeScript, and modern web development.
• Solid understanding of 3D rendering concepts, including scene graphs, meshes, materials, lighting, cameras, coordinate systems, and transformations.
• Practical experience developing and optimizing complex, interactive browser-based 3D applications.
• Strong debugging, analytical, and problem-solving capabilities.
• Ability to independently manage technical deliverables and produce high-quality, maintainable code.

Preferred Experience

• Experience developing Digital Twin solutions for data centers, industrial facilities, smart buildings, or complex physical infrastructure.
• Exposure to NVIDIA Omniverse, OpenUSD, or comparable 3D simulation and Digital Twin platforms.
• Experience with React, React Three Fiber, BIM/IFC, CAD, GIS, or 3D asset optimization workflows.
• Familiarity with large-scale 3D environments, infrastructure simulation, and physics-based visualization.
