• Build self-serve data systems that allow teams to explore, transform, and analyze data with minimal engineering effort
• Develop modular, event-based pipelines across AWS environments, combining cloud flexibility with custom open frameworks
• Automate ingestion, enrichment, and fusion of cybersecurity data including logs, configs, and CTI streams
• Collaborate closely with AI engineers and researchers to operationalize LLM and agent pipelines within the CLM ecosystem
• Implement observability, lineage, and data validation to ensure reliability and traceability
• Scale systems to handle complex, high-volume data while maintaining adaptability and performance
• Own the data layer end-to-end including architecture, documentation, and governance
  
  

• 3+ years of experience as a Data Engineer or Backend Data Developer
• Strong experience with Python, SQL, and modern data frameworks such as Airflow, Spark, or dbt
• Practical understanding of LLM pipelines or agent orchestration frameworks (LangGraph, LlamaIndex, or similar)
• Familiarity with various database systems such as Postgres, MongoDB, Elasticsearch, and vector databases
• Experience building scalable data systems in AWS (EC2, S3, EKS)
• Solid grasp of data modeling, schema evolution, and pipeline observability
• Experience working closely with AI and ML teams
• Strong problem-solving mindset, curiosity, and the ability to move fast while keeping systems clean and reliable
