You will bridge the gap between AI research and production engineering. Your primary focus will be optimizing and scaling core Speech (ASR, TTS) and Language Model (LLM, SLM) pipelines across hybrid cloud and local edge environments.\nKey Responsibilities\nPipeline Deployment & Architecture\nDeploy AI Pipelines:Build production-grade, low-latency pipelines for ASR, TTS, and Small Language Models (SLMs).\nHybrid Deployment:Manage deployment topologies across multi-cloud environments and bare-metal local hardware.\nAPI Development:Create high-performance, asynchronous REST and WebSocket APIs using FastAPI to serve real-time conversational agents.\nMLOps & Infrastructure\nCI/CD Automation:Design automated machine learning pipelines for model testing, versioning, and continuous deployment.\nContainerization:Pack applications using Docker or Podman for consistent execution across dev, staging, and production.\nMulti-Cloud Management:Orchestrate cloud infrastructure across AWS, Azure, and GCP, optimizing for compute efficiency and cost.\nPerformance Tuning & Optimization\nGPU Optimization:Maximize hardware utilization for single-GPU and distributed multi-GPU environments.\nAlgorithm Acceleration:Optimize Python code execution using Numba, NumPy, and specialized CUDA libraries.\nLoad Testing:Conduct rigorous load and stress testing to guarantee system stability under high concurrent traffic.\nRequired Skills and Qualifications\nCore Programming & Frameworks\nLanguage:Mastery of Python and its asynchronous ecosystem.\nML Ecosystem:Deep expertise in PyTorch, Scikit-learn, and NumPy.\nCompilation:Experience accelerating Python code via Numba or Triton.\nConversational AI Experience\nSpeech Technologies:Hands-on experience deploying Automated Speech Recognition (ASR) and Text-to-Speech (TTS) models.\nGenerative AI:Familiarity with optimizing and serving Large Language Models (LLMs) and resource-efficient Small Language Models (SLMs).\nInfrastructure & Operations\nContainers:Advanced knowledge of Docker, Podman, and container orchestration.\nCloud Providers:Practical experience managing AI workloads on AWS (EC2, SageMaker), Azure (Azure ML), and GCP (Vertex AI).\nCI/CD Tools:Experience with GitLab CI, GitHub Actions, Jenkins, or specialized MLOps platforms (e.g., Kubeflow, MLflow).\nPreferred Qualifications\nConversational Context:Experience with dialogue management, prompt engineering, and Retrieval-Augmented Generation (RAG).\nData Analytics:Familiarity with real-time data streaming (e.g., Kafka) and vector databases (e.g., Pinecone, Milvus, Qdrant).\nQuantization:Experience with model compression techniques like quantization (INT8/FP4), pruning, and distillation for edge deployment.","description_format":"text","description_chars":2861,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Professional
