Unity 3D & AR Developer

Duties & Responsibilities: Build the interactive 3D plant walkthrough in Unity, with free navigation and equipment search by tag number. Import and optimize large industrial 3D models (AVEVA ED to Navisworks/FBX), using LODs, mesh decimation, batching, and Addressables so they run smoothly on standard computers. Develop the AR application for tablets and smartphones: scan equipment to retrieve service history, specifications, maintenance schedules, and repair guides, and overlay safety zones and inspection data. Integrate the Unity applications with the EDMS through REST APIs (ASP.NET Core backend), including role-based access to documents. Prepare for later integration with live data sources (SCADA, historians, loT sensors). Build and test on Windows and Android, and work with the 3D modelling and EDMS teams. Conduct site visits to the client's plant to test the AR application on real equipment, validate the walkthrough against the actual plant, and support deployment and acceptance. Deliver training sessions to the client's personnel on using the Digital Plant, the interactive 3D interface, and the AR application (the proposal includes a training programme covering several client departments), and prepare the training material and user guides. Qualifications: Bachelor's degree in Computer Science, Software, or Computer Engineering, or a related field. 1 to 5 years of hands-on Unity 3D development, with strong C# and shipped projects. Proven AR experience with AR Foundation and ARCore (ARKit and Vuforia or similar are a plus), including marker, image, or object-based tracking. Experience optimising heavy 3D scenes (profiling, LODs, occlusion culling, draw calls, memory), with URP or HDRP. Experience importing CAD/BIM/plant models (FBX, Navisworks or similar) into Unity. Solid experience consuming REST APIs and working with SQL databases (MSSQL/MYSQL). Experience with Git or Azure DevOps. Willingness to travel for site visits, comply with plant safety requirements, and present and train nontechnical users with confidence. Send your CV to [redacted email] Show more Show less
