I’ve been out of the metal scene for a little more than 10 years and need some new bands. I’m liking Gojira, do you have any other suggestions? I was really into early All That Remains, As I Lay Dying, A Life Once Lost, and bands like Dead to Fall.

Most of my stuff is of a similar age, although as mentioned Jinjer is great.  I'd throw some songs you love into pandora or Spotify and see what related music they can find for you.  Some of my other similar favorites are meshuggah, lamb of God, Ghost, mastodon, children of bodom, etc. You could also try looking into some subgenres to see if you can find which ones you enjoy more, be it mathcore, doom metal, jazz metal, prog, symphonic, black metal or one of the three hundred others. Wiki is decent for this listing sort of foundational acts for most genres if just start at the heavy metal entry. Generically the guys you listed are probably what I'd call new wave american heavy metal (a huge umbrella) or maybe metalcore.
