Location/Hours of Working

Anywhere. Although ISC is located in the United States, most ISC's staff work from their homes throughout the world.

With staff working from many time zones, there are no set hours of work. We require that staff work forty hours a week, but within parameters set by their manager (e.g., available for meetings, having some overlap with other team members), staff can choose their own working hours. Many of the ISC staff have small children at home, so we understand there might be some volatility in working hours.

This position is suitable for home working. Note that occasional international travel will be required to attend company and team meetings and/or conferences. In the past, these have been held in the USA and Europe.
