hey i found this additional information on the BBC site.

Additionally your duties will include:

3D/CGI design for: in-programme content, VR sets, real time/live graphics for productions such as Elections, VFX
To prepare, collate and research preparatory material to support the design concept and prepare such initial work as necessary to convey the design intention
To manage time, resources and budgets, efficiently and effectively.
To offer cost effective solutions to meet requirements whilst maintaining creative quality and standards.

Sounds pretty good, hope this helps.
There are so many unemployed in the UK now, that i forget how I am pretty lucky to be in work.

btw, not 100% sure what VR sets were, so i googled it and found this guy.
