We'd love to see... 

  • Familiarity working with Client-server protocols such as SOAP, REST

The FlexScore® is the result of a rigorous 2-step verification of a company’s flexibility

First we assess the flexibility options Blip provides and then we anonymously survey a statistically significant proportion of their employees to make sure Blip is as flexible as they say they are. Our assessment is based on the six key elements of flexibility: location, hours, autonomy, benefits, role modelling and work-life balance.

We ask the hard questions so you don’t have to.
