Key Responsibilities
Machine Learning Model Development
- Design, develop, and optimize end-to-end machine learning models for classification, regression, NLP, computer vision, and recommendation tasks.
- Conduct feature engineering, model selection, hyperparameter tuning, and performance evaluation using industry-standard frameworks.
- Ensure models meet production-grade accuracy, latency, and scalability requirements.
Training Pipelines & Data Infrastructure
- Architect and implement scalable ML training pipelines with robust data ingestion, preprocessing, augmentation, and validation stages.
- Design and manage distributed training workflows (single-node and multi-GPU/TPU clusters) using frameworks such as PyTorch, TensorFlow, and JAX.
- Build automated experiment tracking and reproducibility systems using tools like MLflow, Weights & Biases, or DVC.
MLOps & Production Engineering
- Deploy, monitor, and maintain ML models in production using containerized (Docker, Kubernetes) and cloud-native infrastructure.
- Establish CI/CD pipelines for model training, evaluation, versioning, and automated re-training triggers.
- Implement model performance monitoring, drift detection, and alerting systems to ensure sustained model health.
- Manage model registries and artifacts using platforms such as SageMaker, Vertex AI, Azure ML, or open-source MLOps stacks.
Generative AI Development
- Build and deploy production-grade Generative AI applications using leading platforms and open-source models.
- Proprietary: OpenAI GPT-4/o, Anthropic Claude, Google Gemini, Amazon Titan, Cohere
- Open-source: Meta LLaMA 2/3, Mistral, Falcon, Mixtral, Phi-3, Gemma
- Design prompting strategies including zero-shot, few-shot, chain-of-thought (CoT), and structured output prompting for diverse task types.
- Evaluate LLM outputs for hallucination, toxicity, relevance, and faithfulness using automated and human-in-the-loop evaluation frameworks.
RAG, Agentic AI & Fine-Tuning
- Design and implement Retrieval-Augmented Generation (RAG) pipelines with semantic chunking, hybrid search (dense + sparse), reranking, and document parsing strategies.
- Build and orchestrate Agentic AI systems with memory, planning, tool use, and multi-agent collaboration using LangChain, LangGraph, AutoGen, CrewAI, or similar frameworks.
- Apply parameter-efficient fine-tuning (PEFT) techniques, particularly Low-Rank Adaptation (LoRA) and QLoRA, for domain adaptation and instruction tuning of large language models.
- Implement Reinforcement Learning from Human Feedback (RLHF) and Direct Preference Optimization (DPO) pipelines where applicable.
Required Qualifications
- 6–8 years of professional experience in machine learning and AI development.
- Strong proficiency in Python and ML libraries: NumPy, Pandas, Scikit-learn, PyTorch, and/or TensorFlow.
- Proven experience designing and training ML models across supervised, unsupervised, and self-supervised learning paradigms.
- Hands-on experience building and maintaining ML training and inference pipelines at scale.
- Solid MLOps experience: containerization, orchestration, CI/CD, model monitoring, and cloud deployment (AWS, GCP, or Azure).
- Demonstrated experience with at least two major Generative AI platforms (proprietary or open-source).
- Deep understanding of Transformer architecture and large language model internals.
- Practical experience implementing RAG systems with vector databases (Pinecone, Weaviate, ChromaDB, Qdrant, pgvector, Milvus etc.).
- Hands-on experience with Agentic AI frameworks and multi-step reasoning pipelines.
- Working knowledge of Low-Rank Adaptation (LoRA/QLoRA) and other PEFT fine-tuning methods.
