Permanenet Wordpress Admin

I require someone who can work on wordpress on a part time permanent basis
a mixed skillset of Digital Marketing, SEO and to be tech savvy. i am not looking for full experience in all roles but should be able to know their way around a complex wordpress website.
some of the duties involve
1. Banner Creation, Image design
2. Product Listing & Creation ( images, text, placement)
3. On Site SEO
4. Merchandising ( low level) involving product placements based on their ratings within analytics engine
5. General housekeeping of the wordpress website
6. Social media posts and management

a minimum of 20 hours per week required with a maximum of 35 hours a week depending on work needed to be completed

This is an ongoing role that is paid weekly in advance and should the website pick up will look to push this into a more permanent position and full time.
