Key Responsibilities• Voice AI Architecture: Design, build, and deploy low-latency, production-ready Voice AI and real-time conversational pipelines.

• LLM & Speech Integration: Work with STT, TTS, Voice Activity Detection (VAD), LLMs, and NLP frameworks to power natural, real-time voice interactions.
• Backend & API Engineering: Build scalable backend microservices in Python, integrating AI models with enterprise APIs, databases, and third-party platforms.
• Performance Optimization: Fine-tune models and optimize pipelines for latency, high throughput, accuracy, and infrastructure costs.
• Advanced AI Implementation: Implement RAG, vector database retrieval, prompt engineering, embeddings, and function calling into voice systems.
• Deployment & Infrastructure: Manage and scale AI workloads on GPU-based cloud infrastructure or on-premise environments.
• Engineering Leadership: Maintain production system reliability, troubleshoot issues, and mentor junior AI/ML engineers.

Required Qualifications & ExperienceMandatory Requirements• Experience: 5+ years of professional, hands-on experience in AI/ML software development.

• Programming: Expert-level proficiency in Python.
• Frameworks: Strong hands-on experience with PyTorch, TensorFlow, Hugging Face, or equivalent modern AI frameworks.
• LLMs & GenAI: Proven experience building applications powered by LLMs, GenAI, and deep learning architectures.
• Engineering & Deployment: Expertise in building backend APIs, containerization (Docker), CI/CD, Git, and deploying AI workloads on GPU infrastructure.
• Problem Solving: Deep technical troubleshooting, analytical, and architecture design capabilities.

Preferred Experience (Voice AI Focus)• LiveKit / LiveKit Agents experience (Highly Preferred).

• Real-time audio streaming protocols, WebRTC, SIP, and telephony integrations.
• Hands-on work with Voice Activity Detection (VAD), noise suppression, and audio enhancement.
• Voice cloning, custom TTS tuning, and multilingual speech models.
• Engineering low-latency LLM + Voice pipelines for real-time calling/conversational agents.

Additional Advantages• Knowledge of Vector Databases, RAG, Agentic AI, MCP (Model Context Protocol), and Function Calling.

• Hardware acceleration experience: CUDA, TensorRT, GPU memory optimization.
• Infrastructure experience with Kubernetes, AWS, Azure, or on-premise AI deployments.

How to ApplyIf you meet the 5+ years requirement and have hands-on experience building real-time Voice AI systems, please submit your resume along with a summary or portfolio of your production AI projects to hr@infolabsglobal.ai.
