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 Responsibilities
AI & LLM Orchestration
- Design and implement agentic systems capable of multi-step reasoning, planning, and tool usage
- Build state and memory management systems for maintaining context in LLM workflows
- Implement Model Context Protocol (MCP) to enable structured interaction between models and external tools/data
- Develop and optimize RAG (Retrieval Augmented Generation) pipelines using vector databases
Data Engineering & Machine Learning
- Write complex analytical SQL queries for data transformation and analysis
- Design and maintain data warehouse models (fact and dimension tables)
- Build scalable ETL/ELT pipelines to ensure data availability and quality
- Perform exploratory data analysis (EDA) to support model development
- Implement supervised and unsupervised learning models
- Develop solutions such as:
- classification and regression models
- recommendation systems
- clustering and segmentation
Natural Language Processing (NLP)
- Implement and fine-tune NLP models for tasks such as:
- named entity recognition (NER)
- intent classification and translation
- Work with transformer-based architectures (e.g., BERT) to improve text understanding
KPIs
- Successful implementation of agentic workflows and LLM-based systems
- Performance and scalability of data pipelines and ML models
- Accuracy and effectiveness of AI-driven features (RAG, NLP, recommendations)
- Data quality, reliability, and availability across pipelines
- Efficiency of data processing and feature engineering workflows
- Contribution to product intelligence and data-driven decision-making
Must-Have Skills & Experience
- Strong 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 systems
- Strong 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 skills
- Experience with machine learning fundamentals (classification, regression, clustering)
- Experience working with NLP models and Hugging Face ecosystem
Nice-to-Have Skills
- Experience with graph databases (e.g., Neo4j) for GraphRAG or knowledge graphs
- Familiarity with MLOps/DevOps practices (Docker, Kubernetes, CI/CD)
- Experience with DBT
- Understanding of JSON-RPC or MCP architecture
- Experience building advanced RAG pipelines or AI applications in production
Traits
- Strong systems thinker with ability to connect data, AI, and infrastructure
- Curious and experimental mindset, especially in AI and agentic systems
- High attention to detail in data quality and model performance
- Comfortable working in a fast-paced, evolving technical environment
- Strong problem solver with ability to work across multiple domains (AI, data, backend)
