Build optimized data pipeline to support AI applicationsDevelop multi-agent workflows using tools like LangChain, LlamaIndex, LangGraph, Azure, and AWS Bedrock
Integrate MCP tools, APIs, and function-calling into AI systems
Design prompting strategies, embeddings, and vector search pipelines using Milvus / FAISS / Pinecone
Implement structured output generation for LLM responses (JSON/schema-driven outputs)
Apply machine learning techniques (classification, clustering, predictive modeling) for telecom and enterprise use cases
Perform data preprocessing, feature engineering, and model evaluation
Optimize solutions for performance, scalability, cost, and latency
Develop backend APIs using FastAPI for serving AI/ML models
Containerize applications using Docker for scalable deployment
Implement monitoring, logging, and observability using Grafana and ELK stack
Enable LLM traceability and observability using Langfuse etc.
Collaborate with product and engineering teams to deliver production-grade AI solutionsRequired Skills:
2+ years of experience in Data Engineering / AI / Machine Learning /Gen AI
Excellent proficiency in Python and working knowledge of SQL (PostgreSQL preferred)
Hands on Data Engineering experience with big data tools and technology.Hands-on experience with Machine Learning algorithms and model development
Strong understanding of ML concepts: supervised/unsupervised learning, feature engineering, model evaluation, bias-variance tradeoff
Hands-on experience with LLMs, Generative AI, RAG architectures, and Agentic workflows
