The group has said a number of these roles are “suited to young people both in and out of study, with flexible part time positions available”.
Several new roles have also been created as part of the recruitment drive, including a dedicated training and development manager, head of guest experience and public area manager.
Cameron House said that all its employees will benefit from a “three-day induction programme which will provide a complete introduction to the resort and its core values”.
Jennifer Jurgensen, director of human resources at Cameron House, said: “With the hospitality industry as a whole facing such a tough time at the moment it really is a pleasure to be able to announce that we are now ready to start recruiting for over 300 new positions at Cameron House Hotel.
“Having the right team in place that shares our values is crucial to delivering the five-star Cameron House experience. We look forward to welcoming our new recruits, all of whom will be able to enjoy working at one of the most beautiful resorts in the country, set within the breath-taking Loch Lomond and Trossachs National Park.”
