## About the role

We are looking to grow from a team of three (we've accomplished a lot as just two engineers and one designer!) to a clan of around eight, so you'll be anywhere from engineer #3 to #7. You'll be tasked with bringing Poly to life as a robust platform, shaping our cloud architecture to store files at breathtaking speed and scale, and improving our AI architecture to become the "search engine for your life".

## What they're looking for

- Core AI principles and fundamentals around training, inference, loss, gradient descent, embeddings, tokenization and a strong baseline in multivariate statistics
- Extensive experience with modeling / inference tools such as pytorch and CUDA
- Ability to build data pipelines for loading and transforming data with high throughput to a training or inference platform
- Familiarity with modern LLM-based development fundamentals including prompting, function calling, and agentic workflows
- Knowledge of Python is a must, and enthusiasm for Rust is highly encouraged
- An extreme appetite for learning that you've honed through recursive self-improvement. You should be able to demonstrate an exceptional aptitude for automating your own development processes
