Job Summary:

Looking for an experienced iOS XR Developer to create immersive and intelligent XR applications combining AR/VR, 3D avatars, and AI-driven conversational experiences.

The ideal candidate will be skilled in integrating speech-to-text (STT) and text-to-speech (TTS) technologies, working with large language models (LLMs) to drive avatar interactions, and delivering high-quality 3D animations and lip sync for avatars.

  • Build and implement interactive 3D avatars that respond dynamically to inputs generated by LLMs or scripted scenarios.
  • Integrate speech recognition (STT) and speech synthesis (TTS) solutions using platforms like Amazon Polly, Azure Cognitive Services, or Apple’s native frameworks.
  • Develop precise lip sync and facial animation systems using blend shapes, visemes, and other 3D animation techniques.
  • Collaborate with backend teams to integrate RESTful APIs, GraphQL, and real-time data services for dynamic content delivery.
  • Optimize application performance for real-time XR rendering and smooth user experiences on iOS devices.
  • Work closely with UX/UI designers and 3D artists to ensure immersive and visually compelling experiences.
  • Participate in architectural decisions, code reviews, and testing to ensure robustness and scalability.
  • Stay updated with emerging XR, AI, and speech technologies to continuously improve product capabilities.


Required Skills & Qualifications:

  • 3+ years of professional experience developing iOS applications with Swift and Xcode.
  • Strong expertise with RealityKit, ARKit, and SceneKit for native iOS XR development.
  • Proficient in Unity 3D for XR applications, including scripting with C#.
  • Hands-on experience with 3D character animation, blend shapes, rigging, and facial animation techniques.
  • Practical experience integrating speech-to-text (STT) and text-to-speech (TTS) services such as Amazon Polly, Azure Speech, or equivalent.
  • Experience with lip sync implementation aligned with speech input for avatar realism.
  • Familiarity with backend integration (REST, GraphQL, WebSocket) to support dynamic application content.
  • Understanding of large language models (LLMs) for generating conversational or scenario-based text inputs.
  • Solid debugging and performance optimization skills specific to XR environments on iOS.
  • Good understanding of Apple’s Human Interface Guidelines (HIG) and App Store policies.
