AI Engineer — Voice & Language 4+ Years · Full-Time· Jaipur ·Competitive Salary About the Role We're hiring a senior AI Engineer to design, build, and ship production AI systems — with strong emphasis on Voice AI. You'll own the full lifecycle: architecture, training, deployment, and monitoring across language and voice modalities. What You'll Do LLM & GenAI: Fine-tune and deploy LLMs; build RAG pipelines and agentic workflows (LangChain, LlamaIndex). Voice Pipelines: Architect real-time ASR → LLM → TTS pipelines with Voice Agents: Build production voice agents with turn-taking, barge-in handling, and emotion-aware dialogue. Speech Fine-Tuning: Adapt ASR/TTS models for domain-specific accents, terminology, and speaking styles. MLOps: Build reproducible ML pipelines (Kubeflow / MLflow); maintain CI/CD, monitoring, and model versioning. Inference Optimization: Apply quantization (GGUF, GPTQ), distillation, and hardware-aware inference (TensorRT, vLLM) to cut cost and latency. APIs & Services: Ship high-performance inference APIs in Python (FastAPI) or Go on Kubernetes. Data & Evaluation: Curate text + speech corpora; define eval harnesses covering WER, MOS, latency P95, and safety.
