Castlight – Why Work With Us?

When Dr. Giovanni Colella's beloved mother passed away after a long illness, helping Americans get the best possible care for themselves and their loved ones became very personal.

Despite being a trained physician, Giovanni experienced first-hand how difficult it is to navigate the system, to understand healthcare options as well as the cost and quality of care. This led to the founding of Castlight and our mission: to empower people to make the best choices for their health, and help companies make the most of their health benefits.

Today, we’re proud that the best engineers, economists, clinicians and product developers in our industry are improving our customers’ businesses, the lives of American families and the healthcare system, one day at a time.

    Average Interview


    I applied online. I interviewed at Castlight.


    One interviewer called me an hour before scheduled time, next interviewer forgot I was coming in and had no idea who I was. Last interviewer spent 20 minutes. I felt that their hiring practices were scattered.
