The Cloud Travel group builds web travel portals for B2B partners, expanding into a B2C offering soon.

A successful candidate will demonstrate a high sense of ownership of outcomes and consistently look for creative ways to deliver results quickly, being able to tell between what has to be right from the start and what can be iterated on.
