Guitarist/backing vox needed for pre-established metal band

Hi looking for a guitarist/backing vocalist to as a 4th to join a metal band (bass, drums and harsh vox already covered).

Will involve remote writing sessions every week/fortnight and once established practices in London.

Backing vocalist able to cover live gigs during the vocalists period of absence would be a huge bonus - (vocalist will be remote only for a period of time)

Influences:
Messugah
Opeth
Mastadon
Lamb of God

We have a decent amount of songs which are partially and fully written - this is an example of one using midi guitars for our current project.

And here is one from a different previous project from two of the bandmates (using actual guitars).
