An Insider's view of Ranker

How does your team reward individual success?

What I love about being a part of Ranker's Audience Development team is that one person's success is celebrated not just as a personal victory, but as a triumph for our whole team. Every day we are encouraged to step outside of the box and speak our minds; to be creative and analytical without fear of rejection.

What projects are you most excited about?

The best part about working at Ranker is the wide variety in the types of projects we might work on. We could be working on site optimization one week and creating big data management systems the next. Our latest project is a soon-to-be-released TV recommendation app that utilizes the latest in web development and machine learning tech.
