AI Data Engineer

We are looking for an AI & Data Engineer to build and scale next-generation intelligent systems. This role goes beyond traditional model development, you will design agentic workflows that can reason, remember, and act autonomously.You will bridge the gap between data engineering, machine learning, and LLM-based systems, creating robust pipelines and integrating them with modern AI frameworks. This role is ideal for someone who enjoys working at the intersection of AI, data infrastructure, and system architecture.

Key ResponsibilitiesAI & LLM OrchestrationDesign and implement agentic systems capable of multi-step reasoning, planning, and tool usageBuild state and memory management systems for maintaining context in LLM workflowsImplement Model Context Protocol (MCP) to enable structured interaction between models and external tools/dataDevelop and optimize RAG (Retrieval Augmented Generation) pipelines using vector databasesData Engineering & Machine LearningWrite complex analytical SQL queries for data transformation and analysisDesign and maintain data warehouse models (fact and dimension tables)Build scalable ETL/ELT pipelines to ensure data availability and qualityPerform exploratory data analysis (EDA) to support model developmentImplement supervised and unsupervised learning modelsDevelop solutions such as:classification and regression modelsrecommendation systemsclustering and segmentationNatural Language Processing (NLP)Implement and fine-tune NLP models for tasks such as:named entity recognition (NER)intent classification and translationWork with transformer-based architectures (e.g., BERT) to improve text understanding

KPIsSuccessful implementation of agentic workflows and LLM-based systemsPerformance and scalability of data pipelines and ML modelsAccuracy and effectiveness of AI-driven features (RAG, NLP, recommendations)Data quality, reliability, and availability across pipelinesEfficiency of data processing and feature engineering workflowsContribution to product intelligence and data-driven decision-making

Must-Have Skills & ExperienceStrong proficiency in Python (FastAPI, Pydantic, Pandas, Scikit-learn, PySpark)Hands-on experience with LLM/AI frameworks (e.g., LangChain, LangGraph)Experience building or working with agentic workflows or AI-driven systemsStrong experience with relational databases (PostgreSQL, Snowflake, BigQuery)Experience with vector databases (Pinecone, Milvus, Weaviate, pgvector, etc.)Solid understanding of data warehousing concepts (star/snowflake schema, fact/dimension modeling)Experience building ETL pipelines (Python, Airflow)Strong SQL and data modeling skillsExperience with machine learning fundamentals (classification, regression, clustering)Experience working with NLP models and Hugging Face ecosystem

Nice-to-Have SkillsExperience with graph databases (e.g., Neo4j) for GraphRAG or knowledge graphsFamiliarity with MLOps/DevOps practices (Docker, Kubernetes, CI/CD)Experience with DBTUnderstanding of JSON-RPC or MCP architectureExperience building advanced RAG pipelines or AI applications in production

TraitsStrong systems thinker with ability to connect data, AI, and infrastructureCurious and experimental mindset, especially in AI and agentic systemsHigh attention to detail in data quality and model performanceComfortable working in a fast-paced, evolving technical environmentStrong problem solver with ability to work across multiple domains (AI, data, backend)
