The ideal candidate should have a strong foundation in data engineering principles, understanding of different data pipelines and the ability to optimize and scale data processing and analytics solutions.

Qualifications:

Core Data Engineering Skills

• 7+ years overall experience in Big Data or Enterprise large-scale application development using scalable tools like Databricks, Scala, Java, and the Python ecosystem.
• 5+ years of relevant experience in Technology implementing data-intensive solutions using agile methodologies.
• Deep understanding of data modeling, data warehousing concepts, methodologies, and best practices.
• Strong experience with data processing (e.g., Spark, Starburst, Snowflake, Redshift), storage (e.g., Hadoop, MongoDB, Oracle), and ETL (e.g., Airflow, Ab Initio, Talend) solutions.
• Experience with data engineering techniques such as building data lakes and data warehouses, data mesh architectures, data pipelines, and ETL vs. ELT patterns.
• Strong expertise in Starburst/Trino with deep understanding of data federation and data virtualization architectures.
• Experience with real-time data processing and data virtualization technologies such as Starburst, Snowflake, and Flink (preferred).
• Experience with designing and developing distributed systems, handling structured and unstructured data to store, analyze, and report.
• Experience with developing and maintaining large and complex database systems using relational databases like Oracle, and other big data technologies like Hadoop, Spark, etc.

• Practical knowledge of Model Context Protocol (MCP) servers, including:
  • Setting up and configuring MCP servers to expose data tools, database connections, and APIs as contextual resources for LLM-powered agents.
  • Designing MCP-compatible tool interfaces that allow agents to query, transform, and validate data autonomously.
  • Understanding MCP's client-server architecture and its role in enabling secure, standardized communication between AI agents and enterprise data systems.
• Understanding of Retrieval-Augmented Generation (RAG) principles, including vector databases (e.g., Pinecone, Weaviate, ChromaDB) and advanced retrieval techniques for grounding agents in enterprise data.
• Awareness of Large Language Models (LLMs) (e.g., OpenAI, Gemini, Claude, Llama) and their practical application in data engineering contexts such as automated schema inference, natural language querying, and intelligent data cataloging.

Education:

• Bachelors degree/University degree or equivalent experience
