## About the role

SID trains AI that can retrieve and reason over any data source. Intelligence and skills are inconsequential without context. Today, AI is blind to information that is not on the internet. If we want AI to solve real problems, we need to change that. SID.ai is backed by Y Combinator, Canaan, Rebel, and General Catalyst – as well as a great set of angels.

## What they're looking for

- Not afraid of formulas – a technical major 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 RL pipelines for language models
- Comfortable with torchrun/accelerate/multi-node training
- Clever about getting the data needed – or synthetically generating it
