XR Application Development - Develop, test, and deploy XR applications using Unity 3D, C#, AR Foundation, OpenXR and related frameworks. - Create realistic 3D interactions, physics-based simulations, and immersive user experiences for surgical robotics. - Integrate and optimize shaders using High-Level Shading Language (HLSL) for advanced visual effects, lighting, and rendering. - Integrate XR hardware such as Hololens, Meta Quest, Varjo, and HTC Vive for training and visualization use cases. - Optimize rendering, loading, memory usage, and interaction performance for smooth real-time simulation. - Collaborate with design teams to import, manage, and refine 3D assets, including robotic and anatomical models. 2. Simulation, Training & Visualization Modules - Build XR modules for surgeon training, workflow walkthroughs, digital twins, and procedural simulations for MISSO 4000. - Implement step-based guided instructions, interactive UI/UX, and multi-user collaboration features as required. - Support clinical and product teams during demonstrations, usability studies, and validation sessions. 3. Technical Support & Troubleshooting - Debug application issues across devices, platforms,



and XR environments. - Work with robotics, hardware, and software teams to ensure seamless integration with the MISSO 4000 ecosystem. - Perform continuous testing to identify performance gaps and implement corrective improvements. 4. Documentation & Compliance - Maintain documentation for code, architecture, implementation steps, and development workflows. - Prepare user guides, training materials, and technical notes for internal teams and external stakeholders. - Ensure adherence to company SOPs, data security protocols, and medical device software guidelines. 5. Cross-Functional Collaboration - Collaborate with Robotics, Clinical, R&D;, Product Management, and Quality teams to gather feedback and refine XR modules. - Participate in internal validation, UI/UX reviews, and prototype testing before feature releases. Provide technical insights supporting product development, engineering decisions, and market readiness efforts. 6. Customer & Internal Stakeholder Engagement - Support internal demos, customer presentations, and clinical training initiatives through XR-based tools. - Provide post-demo support, updates, and improvements based on user or clinician feedback. - Ensure a high-quality, reliable XR experience that enhances surgeon confidence and system usability. Qualifications and Experience:



- Bachelor’s / Master’s degree in Computer Science, Game Development, Engineering, or related discipline. - Minimum 3-4 years of hands-on experience in Unity 3D and XR application development. - Strong understanding of AR/VR/MR frameworks, OpenXR, AR Foundation, XR Interaction Toolkit. - Experience working with real-time 3D graphics, shaders, animation systems, and rendering pipelines (URP/HDRP). - Hands-on experience with HLSL shader programming, rendering pipelines (URP/HDRP), lighting, and GPU optimization. - Exposure to medical simulation, robotics, training systems, or industrial visualization (preferred). - Experience with Git, Agile workflows, and cross-platform deployment. Skills and Competencies: - Proficiency in C#, Unity engine, and XR development tools. - Robust analytical, debugging, and performance optimization skills. - Strong experience with HLSL shaders, rendering optimization, and real-time graphics - Excellent communication skills with the ability to collaborate across technical and clinical teams. - Creative problem-solving mindset with attention to detail and usability. - Familiarity with 3D modelling tools (Blender, Maya, 3ds Max) is a plus. - Ability to work on-site and support multi-functional development cycles. Key Performance Indicators (KPIs): - Quality, stability, and performance of XR applications delivered. - Timely completion of modules, prototypes, and feature enhancements. - User experience feedback from surgeons, trainers, and internal teams. - Contribution to product improvement, training efficiency, and simulation readiness. - Reduction in technical issues, rework, and XR integration gaps.
