We are seeking a highly experienced ML/AI Architect to design, build, and scale enterprise-grade AI/ML and GenAI solutions within our Digital Transformation Practice.

The role requires strong technical leadership across ML system architecture, LLM-based solution design, MLOps automation, and cloud-native data engineering.

The ideal candidate will drive innovation, establish best practices, and deliver production-ready AI solutions at scale.

Roles & Responsibilities :

- Architect end-to-end ML systems covering data ingestion, feature engineering, model training, deployment, and monitoring.

- Design scalable ML pipelines for classical ML, deep learning, and GenAI workloads including LLMs, RAG, embeddings, and semantic search.

- Select optimal algorithms, frameworks, and cloud platforms to address complex business and technical challenges.

- Implement model optimization strategies such as quantization, pruning, distillation, and LoRA/QLoRA fine-tuning.

- Build LLM-powered solutions using prompt engineering, knowledge grounding, agents, and retrieval-augmented generation.

- Work with top LLMs (GPT-4/5, Llama 3/3.5, Qwen, Claude, Gemini) and integrate vector DBs like Pinecone, Weaviate, Chroma, Milvus.

- Evaluate and improve LLM and ML model performance, reduce hallucinations, and ensure security and compliance.

- Lead development of ML, NLP, NER, and deep learning models using Transformers, CNNs, XGBoost, and other advanced architectures.

- Drive data science workflows including EDA, feature engineering, statistical modeling, and explainability (SHAP/LIME).

- Architect MLOps pipelines (CI/CD/CT), enabling model versioning, monitoring, drift detection, and automated retraining.

- Deploy models at scale using Kubernetes, Docker, Terraform, serverless components, and GPU-based environments with strong observability.

- Collaborate with cross-functional teams, lead technical discussions and POCs, and mentor ML/AI teams to deliver enterprise-grade solutions.
