That's nice, but you're posting on reddit with a throwaway account, so spam is going to happen. You're also asking for a specialized skillset in a niche area. The candidates you would be looking for already would be turned off by a generalized job posting. So the pool you would attract is somewhat desperate new grads with interests in the field. Hemce this has an exploitive vibe.

If good faith: just name your company so your hiring pool knows you're genuine. It'll make your life easier

If bad faith: just remove post before mods do it.

Disclaimer: I don't do graph networks so am uninterested in posting. I'm just over exploitation in tech.
