The heritage railway, for vintage steam and diesel haul trains, is volunteer-led and open every weekend between Easter and Halloween - attracting around 40,000 visitors a year.
The new catering manager will work approximately 2.5 days a week and will be responsible for maximising profits and providing excellent customer service.
EOR is on the hunt for a catering professional who is a strong leader, communicator and team player, and who also has a sense of humour and is flexible.
Dean Walton, EOR business development manager, said: "We employed a full-time catering manager on a fixed term contract to transform our catering services. That transformation is done and the focus this year is on delivery - via a new part-time post.
“All our staff and volunteers come with bags of humour - working in an intense and high-profile visitor attraction, I think it can help you get through the day and, more importantly, will help them fit in!"
