It sounds like grindcore with post-rock/hardcore influences, I don't think doing so will result in making grindcore "post". I think post-grindcore would be something more similar to technical death metal (Pyrrhon?)
If I had to put it in just a genre, I'd say some bullshit like "melodic grindcore", but that doesn't sound cool.

There is no post anything. Talk talk - spirit of eden is almost 30 years old, f#a# infinity almost 20.

Pig destroyer are post grindcore.

Grindcore mixed with post-rock has already been done, and way better

you know we have threads for you to shill your bandcamp in right you don't have to do this

also this is some pretty bad shit
playing generic arpeggios for 30 seconds before you play hardcore at like 100bpm for a minute doesn't make you "post-grindcore"
