About Us

Data Works, an E3/Sentinel Company, is a Big Data software services company primarily supporting the Intelligence Community. Our core competency is in the technical stack between collection and analysis.

Founded in 2006, we have grown over the years by hiring top-notch talent and providing them with great compensation, benefits and career opportunities. We favor a high quality workforce over aggressive growth and provide opportunities on programs that fill mission-critical needs.

Our flat structure with constant employee outreach and interaction has yielded a satisfaction rating of 97% with less than 3% annual turnover. Outside of the customer we connect with employees and their families via happy hours, charity events, and family outings.
