• 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.
• 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.
