Workday specialist

Our partner Verama, need for a resource to support with structuring our Workday knowledge base. In the knowledgebase we store all information related how to operate in our Workday system. Our WiKi site have around 8-10.000 visits every month. We are currently using a sharepoint WiKi solution and it has grown over the years to become rather extensive. We lack a bit of structure and commonalities between process areas and documents. We have several persons updating the documentation from their best ability but we need a way of working and guidelines. What type of documentation is needed for our readers, detail level, training material and/or information etc. This person need to have enough skills in Workday to be able to edit content and make the different documents consistent in terms of structure, language, content. There are also instruction movies to be recorded and we are also open to e.g eLearnings and other good input. The person must be fluent in English.
Since Workday is the system we are using we need someone with knowledge within Workday but more importantly someone who really knows how to structure the documentation around how to operate in the system. Also important to have good knowledge in Sharepoint or at least be familiar with it and learn the missing pieces.
We believe we need a resource full time, or at least close to, for 3 months. Start date to be discussed but sooner rather than later.
