Identifies performance bottlenecks and refactor inefficient data processes. Recommends improvements to schema design, data granularity, and source-system integration. Maintains awareness of industry standards for data governance, security, and accessibility. Supports automation of routine data workflows and manual reporting processes. Works closely with analysts, data scientists, application developers, and stakeholders to deliver high-quality datasets. Coordinates with system owners and system administrators to manage source data access and schema changes. Supports QA and testing teams by validating expected output and data quality criteria. Participates in data and AI design reviews, standups, retrospectives, and sprint demos. Communicates technical limitations or trade-offs to business stakeholders in an understandable way. Partners with cybersecurity teams to ensure sensitive data is handled securely and in compliance with County policy. Continues building technical proficiency in cloud platforms, big data tools, and AI frameworks. Stays current with trends in data engineering, streaming pipelines, and ML Ops practices. Contributes to internal wikis, playbooks, and best practices documentation. Mentors junior data engineers or interns on development and testing practices. Participates in knowledge-sharing sessions, communities of practice, or hackathons. Proactively seeks opportunities for cross-training with related disciplines (e.g., AI, Big Data, DevOps and MLOps). Implements robust LLM engineering practices using tools like Langfuse or Weights & Biases for tracing, debugging, and evaluating model outputs. Tracks personal learning goals and reflects on performance improvement opportunities. Communicates progress, risks, and needs to project leads or data managers. Documents data sources, logic, and transformations in data dictionaries or metadata repositories. Supports stakeholder training or onboarding on new datasets and data services. Assists in writing user guides, technical diagrams, and documentation for AI Orchestrations and data pipelines. Participates in requirement gathering and feedback sessions with business users. Supports audit and compliance documentation as needed. Provides timely responses to questions or data requests from supported teams. Coordinates deployment of data updates with impacted teams or systems. Performs other duties as assigned.
