There's plenty of great artists with more high oriented harsh vocals in their repertoire, hell, vast majority of some genres are like that, but that's too much variety for good recommendations (essentially, vocal style is fairly poor as the sole basis for recommendations). Since you did mention death metal though, you should probably give the "originals" a spin. The band Death does not have exactly this type of highs, but highs nonetheless, and their music is some quality death metal
EDIT: also might wanna avoid using "screamo", as it will trigger quite a few connoisseurs of metal (myself included), since screamo typically refers to specific small emo subgenre of that name ¯\_(ツ)_/¯
