Project/System Overview
Connecticut’s Criminal Justice Information System (CJIS) is the umbrella term for the activity among agencies with criminal justice responsibilities to bring greater cohesion and effectiveness by improving the way they communicate and share information across system components, and how they manage data on crime and criminal offenders. As part of ongoing CISS initiatives, CJIS-CT is expanding into building a product called CISS Analytics as per the CISS legislation.
The key purpose of the CISS Analytics is for the CJIS Analytics sub-committee to utilize it to help make changes in laws and policies to serve the interests of Connecticut residents and relevant state agencies. To support this effort, CJIS-CT seeks a Data Scientist who can transform data into actionable insights and scalable machine learning solutions. You will work cross-functionally with CJIS SQL DBA, Business, Source data owners, and the Analytics sub-committee teams to solve complex problems and create data that would be used for informed decision-making.
