    DEFINITION:

    Under general supervision, leads the development and application of methods to identify, collect, process, organize, and analyze structured and unstructured data using advanced statistical prediction, inference, and optimization; effectively communicates results to County, departmental, and divisional decision makers and provides ongoing support to strengthen data-driven program design and management.

    CLASSIFICATION STANDARDS:

    Positions allocable to this class typically report to a Data Scientist Supervisor or a higher-level position responsible for the data analytics, research, or statistical function of a department, and serve as data science project leads and subject matter experts assigned to large and complex data science projects. Incumbents utilize advanced expertise in data science, including standard software tools and programming languages, advanced statistical design and modeling, predictive and prescriptive analytics, and visualization; and are conversant in the principles of data engineering and architecture, contributing to the design of systems to be used by their teams. Senior Data Scientists work collaboratively with both technical and nontechnical partners to develop and complete large-scale projects in response to identified business needs and oversee teams of data scientists and analysts as part of a large-scale project. Incumbents coordinate and contribute to complex projects that require using advanced methods of data science such as cloud-based data design; data extraction, transformation, and loading; statistical analysis and machine learning; data visualization; and placement of predictive models, automated dashboards, and other data science products into production. Incumbents present their findings to technical and nontechnical stakeholders to support data-driven program design and management; and provide and/or delegate ongoing consultation services to client programs to assist with implementing recommendations as necessary.

    Senior Data Scientist is distinguished from Data Scientist in that Senior Data Scientists apply advanced methods of data science to identify new and emerging business problems within their assigned departments and may lead project teams of Data Scientists and other analyst staff.

    Positions in this class differ from those that plan, design, conduct and evaluate research projects involving complex experimental designs and data analysis, programming and processing of data, and preparing reports and recommendations based on research findings, in that these classes do not employ machine learning or big data as part of their analyses.
