350 jobs could be created at the Amazon fulfilment centre in Rugeley, after the firm applied for planning permission to expand the building.
The jobs at the Towers Business Park will only be created however, if the application is successful.
If approved, there will be a new entrance to the building, and improved infrastructure around the site. The interior of the building will also be reconfigured so the capacity will be doubled.
The company has also said it plans to create about 2,500 seasonal roles in Rugeley this Christmas.
