• Design, deploy, and manage vector database solutions (Databricks Vector Search, Pinecone, or similar) for semantic search and retrieval across enterprise documents.
• Lead LLM fine-tuning and customization initiatives, training models like Claude or open-source alternatives with CIM proprietary data while ensuring data privacy and compliance.
• Develop and optimize document processing pipelines including PDF parsing, chunking strategies, and embedding generation for RAG applications.
• Implement prompt engineering best practices and LLM evaluation frameworks to ensure output quality, relevance, and factual accuracy.
• Build guardrails and safety measures for GenAI applications, including hallucination detection, output validation, and source attribution.

Automation & CI/CD Pipelines

• Design and implement extensive automation across the ML workflow, covering model training, testing, validation, and deployment using Databricks Workflows and Asset Bundles.
• Set up robust CI/CD pipelines for both traditional ML models and GenAI applications, leveraging GitHub Actions, Azure DevOps, or similar tools.
• Automate complex data and model workflows utilizing orchestration tools such as Airflow, Prefect, or Databricks Workflows.

Monitoring, Performance & Reliability

• Implement comprehensive monitoring and alerting systems for real-time tracking of model performance, data quality, and GenAI output quality.
• Utilize specialized tools (Evidently AI, WhyLabs, Prometheus/Grafana) to proactively detect model drift, data quality anomalies, and RAG retrieval degradation.
• Develop evaluation frameworks for GenAI applications including relevance scoring, faithfulness metrics, and human feedback loops.
• Troubleshoot issues within production environments, including debugging model deployment failures, RAG retrieval issues, and LLM response quality problems.

Data & Feature Engineering Support

• Build and maintain sophisticated feature stores on Databricks, ensuring precise alignment between training and inference data pipelines.
• Collaborate with data engineers and information architects to build robust ETL pipelines that feed into the Databricks Lakehouse.
• Design embedding pipelines and vector index management strategies for RAG applications, including incremental updates and versioning.

Security, Compliance & Trustworthy AI

• Integrate robust security measures directly into ML Ops and GenAI pipelines, including access controls via Unity Catalog and data encryption.
• Implement Trustworthy AI guardrails addressing bias detection, explainability, prompt injection prevention, and responsible AI practices.
• Ensure GenAI applications handling sensitive fund and investor data comply with regulatory requirements and internal policies.
• Collaborate with Legal and Compliance to establish AI governance policies and audit trails for model decisions.

Collaboration & Business Partnership

• Engage in extensive collaboration with data scientists, platform engineers, information architects, and DevOps teams to ensure seamless ML/AI integration.
• Partner with business teams (Fund Accounting, FP&A, Investor Relations, Sales, Investments) to identify high-value AI use cases and translate business needs into technical solutions.
• Communicate complex AI concepts in business terms, managing expectations and demonstrating ROI of ML/GenAI initiatives.
• Provide technical mentorship to team members, including refactoring data scientist code for production readiness.
