About SID

AI research lab for retrieval. Backed by Y Combinator.

About the role

If you don't match all of the requirements, we still encourage you to apply. We care much more about potential and the rate of improvement than achievements. We train and invest in our people!

What they're looking for

  • Not afraid of formulas – a BSc/MSc/PhD is an indicator of this (but isn't the only one)
  • Thinks they can learn anything in 2 weeks, but isn't arrogant about it
  • Prefers .py to .tex
  • Familiar with vLLM/SkyRL/Megatron/etc
  • Comfortable with torchrun/accelerate/multi-node training
  • Clever about getting the data needed – or synthetically generating it
