NONCONFIDENTIAL // EXTERNAL
IT BOA Job Category: Artificial Intelligence
Job Title: Senior Data Scientist
Period of Performance: 6 months
Position Summary
The client is establishing an AI Lab to explore and implement generative AI and machine learning solutions
that enhance staff productivity, improve analytical capabilities, and strengthen the Division's
work in consumer protection and community development. We are looking for a full-stack
Senior Data Scientist to support the AI Lab's research, development, and implementation of
AI/ML solutions, with emphasis on generative AI applications. This role requires end-to-end
ownership, from exploratory research and model development through application deployment
and production maintenance. The ideal candidate is comfortable working across the full
technology stack: building models, creating visualizations, developing applications, and
deploying solutions to on-prem and/or cloud infrastructure.
The AI Lab operates as a small, agile team where practitioners are expected to move between
research, development, and deployment activities. This position will contribute to strategy while
doing hands-on technical work, building models, training systems, evaluating performance, and
deploying solutions. The AI Lab collaborates closely with DCCA's Data Analytics and Risk and
Surveillance sections, and coordinates with the Board's enterprise technology on infrastructure,
governance, and compliance matters.
Responsibilities
AI/ML and Generative AI Development
Research, design, and develop machine learning and artificial intelligence solutions to
support DCCA's mission, with emphasis on generative AI applications
Build and iterate on proof-of-concept AI solutions that demonstrate value for specific use
cases, transitioning successful prototypes into production applications
Design and implement applications leveraging large language models for text analysis,
summarization, information extraction, document classification, and workflow
automation
Develop prompt engineering strategies and retrieval-augmented generation (RAG)
systems to improve AI application performance
Experiment with fine-tuning, model customization, and evaluation techniques to optimize
AI solutions for DCCA use cases
Evaluate emerging AI technologies, frameworks, and models to identify opportunities for
adoption within DCCA workflows
NONCONFIDENTIAL // EXTERNAL
Apply advanced statistical and machine learning techniques including
supervised/unsupervised learning, classification, regression, and deep learning methods
Deployment and Operations
Build, deploy, and maintain AI/ML models and applications in cloud environments
(AWS, Kubernetes, or internal analytics platforms), working collaboratively with AI
Cloud Engineers when available or independently managing end-to-end deployment
Develop interactive dashboards and analytical applications using Python frameworks
(Streamlit, Dash, Flask) or R Shiny; leverage AI-assisted development tools to rapidly
prototype and iterate on data products
Create data visualizations and user interfaces using Python libraries (Plotly, Matplotlib,
Seaborn), R (ggplot2), Tableau, Power BI, or similar tools that translate analytical outputs
into intuitive, actionable insights for non-technical audiences
Manage deployment pipelines including containerization (Docker), CI/CD practices, and
GenAI application deployments with API integrations, rate limits, and cost optimization
Implement monitoring, logging, alerting, and visual dashboards for model performance,
data quality, and system health; establish automated retraining pipelines and model
versioning strategies
Troubleshoot and maintain deployed applications, addressing performance issues,
ensuring scalability, and updating applications as requirements evolve
Support governance requirements including documentation for security assessments,
privacy reviews, and compliance obligations related to deployed systems
Collaboration, Communication and Agile Practices
Work within a light agile framework, participating in sprint planning, standups, and
retrospectives to coordinate work with team members
Break down technical work into manageable tasks, estimate effort, track progress, and
communicate status, blockers, and technical challenges to stakeholders
Work directly with DCCA program staff economists, analysts, attorneys, and senior
leadership to understand business needs, identify AI/ML opportunities, and translate
requirements into technical solutions
Communicate technical concepts effectively to both technical and non-technical
audiences through presentations, reports, and executive summaries

interpretability, and transparency in model development
Maintain awareness of AI ethics, accountability, and appropriate use considerations in
federal regulatory contexts
Support preparation of documentation for system security plans, privacy impact
assessments, and authority to operate processes when required
