## About the role

Our ultimate goal is to build perfect search over all the world's information, far beyond Google. If you want to build massive-scale ML systems that will define the way the new AI world consumes information, this is the place for you. As a backend engineer, you'd play a critical role in our search architecture. We're pretty flexible on what projects people work on based on their skills and interests. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Graduate-level ML experience (Master’s or PhD with at least 2 years of relevant experience), or an exceptionally strong undergrad
- You can build a transformer from scratch in PyTorch, and you have trained models that then had to be cheap enough to run everywhere
- You like building large-scale datasets and living in the data. Most of the wins here are in the supervision rather than the architecture
- You are comfortable with problems where the ground truth does not exist yet and defining it is part of the job
- You care about the problem of finding high quality knowledge and recognize how important this is for the world
