The scope of key responsibilities and activities include but is not limited to the following: Full-Stack Development with GenBI/GenAI and AI/ML, and Ongoing M&O

• Effectively apply User Interface (UI)/ User Experience (UX) design principles for designing and building analytics dashboards with technologies such as Chainlit, Streamlit, and React.
• Create interactive reporting and storytelling based on data visualization best practices, and humancentered design.
• Leverage Out-of-Box (OOB) services/functions/APIs (e.g., calling SNOWFLAKE.CORTEX functions via SQL or configuring AWS Bedrock Knowledge Bases) to accelerate the design and implementation of use cases.
• Build automated tests to ensure the platform's Text-to-SQL engine isn't hallucinating incorrect numbers.
• Perform continuous prompt engineering to guide and finetune the platform's system behavior.
• Execute statistical analysis, predictive analytics, optimization; conduct AI/ML model prototyping with ML frameworks such as TensorFlow, PyTorch, scikit-learn.
• Apply expertise in platform-specific semantic layers or dbt (Data Build Tool), advanced SQL and dimensional modeling (Star Schema), and cloud ML platforms (e.g., AWS SageMaker, Azure ML, GCP Vertex AI)
• Implement containerization and orchestration (Docker, Kubernetes).
• Operate CI/CD pipelines for ML and data workflows, data integration, cleaning, and transformation processes.
• Responsible for monitoring, tuning, and logging for AI/ML and GenBI solutions, Extract, Transform, Load (ETL)/ Extract, Load, Transform, (ELT) pipelines (e.g., Airflow, Matillion), cloud data warehouses & lakes (e.g., Snowflake, Redshift, BigQuery, Azure Synapse), and cloud infrastructure automation (e.g., Terraform, Ansible).
• Continuously enhance and verify that the entire IDW ecosystem/solution are cost-effective, secure, and scalable.
• Provide technical leadership, solution guidance to project teams in support of solution design and development, and act as a technical liaison among Investment stakeholders, technical developers, 3rd party vendor teams and tech support.
• Apply vast experience and multidisciplinary expertise in AI Infrastructure & Agentic Workflows/Orchestration, Generative AI Design Patterns, Cloud Strategy & FinOps, and Security & Compliance (AI Governance) to support key Investment's initiatives.
• Analyze solutions and technologies and make recommendations based on knowledge of CalSTRS Investment Branch's current and future needs.
• Proactively monitor and assess strategic direction of solution vendors, technology and market trends, and determine their potential impact and value to the IDW; prepare presentations, documents, diagrams, models, and other artifacts as required to communicate analysis, recommendations, or designs
