AI Developer

Job Summary

We are building Kyra -an AI-powered health and fitness coach that provides personalized nutrition advice, analyzes medical and lab reports, scans food for nutritional information, creates workout and wellness plans, and interacts with users through a speaking 3D avatar with real-time lip sync.

We are looking for an AI Developer who can build and fine-tune custom AI models, integrate multimodal AI pipelines, and bring Kyra to life as an intelligent conversational health companion.

Key Responsibilities

• Design and develop the core AI engine for Kyra with context-aware, multi-turn conversations covering nutrition, exercise, supplements, sleep, stress, and overall wellness.
• Build a food recognition pipeline using computer vision models such as YOLO , EfficientNet , or custom CNNs to identify food items and estimate nutritional values.
• Develop a medical and lab report analysis module using OCR technologies like Tesseract and PaddleOCR , combined with NLP for extracting biomarkers and generating health insights.
• Create a personalized recommendation engine for workout plans, diet suggestions, wellness challenges, and habit tracking based on user goals and historical data.
• Fine-tune and deploy Large Language Models (LLMs) using Python , PyTorch , TensorFlow , and Hugging Face Transformers .
• Develop Retrieval-Augmented Generation (RAG) pipelines using vector databases such as Pinecone , Weaviate , or ChromaDB .
• Build a real-time 3D avatar speech and lip-sync pipeline by integrating Text-to-Speech engines, phoneme extraction, and viseme mapping.
• Implement voice interaction using Speech-to-Text technologies like Whisper , natural language understanding, and conversational AI workflows.
• Design prompt engineering frameworks, AI guardrails, and safety filters to ensure medically responsible responses.
• Develop evaluation frameworks to measure model accuracy, response quality, hallucination rates, and user satisfaction.
• Optimize inference performance through model quantization, batching, caching, and GPU/CPU resource management.
• Collaborate closely with backend, frontend, and 3D development teams to integrate AI services into the product.

Requirements & Qualifications

• 2-4 years of experience in AI/ML development with expertise in NLP, Computer Vision, or Conversational AI.
• Strong Python programming skills with extensive experience using PyTorch or TensorFlow .
• Hands-on experience fine-tuning Large Language Models such as GPT, LLaMA, Mistral, or similar foundation models.
• Experience designing and deploying Retrieval-Augmented Generation (RAG) architectures and vector databases.
• Strong understanding of computer vision techniques including image classification, object detection, and OCR.
• Experience with speech technologies including Text-to-Speech (ElevenLabs, Coqui, Azure TTS), Whisper, and audio processing.
• Knowledge of 3D avatar animation pipelines, lip-sync technologies, viseme mapping, and blend shapes.
• Experience with LangChain, LlamaIndex, or similar LLM orchestration frameworks.
• Strong understanding of prompt engineering, structured output generation, and AI safety practices.
• Experience deploying machine learning models using FastAPI, model versioning, monitoring, and A/B testing.
• Familiarity with cloud-based ML services such as AWS SageMaker, Google Vertex AI, or Azure Machine Learning.
