This role is open to the US only, and does require 3 days per week in-office in San Francisco, California.

- Fine-tuned models for our specific needs.
- Developed new processes to speed-up how we migrate to new AI models.
Show off in your application! (Important)
When applying, include a quick demo of something you made with LLMs that you’re really excited about. It should showcase your fit for the role. Include it in any form you’d like (such as a link to a short video or a repo).

WHY YOU SHOULD JOIN US

- We embrace being fully remote. We schedule meetings sparingly and instead heavily use async comms (Slack, Notion, Loom)
ABOUT THE INTERVIEW
- You’ll meet the entire team. We think it’s important that you get to meet everyone you’ll be working with.
- No bullshit. Ask us anything you like. We’ve never understood why companies pretend they’re something that they’re not in the hiring process - you’re going to find out eventually so we’d rather you know who we are up front so we can both make sure this is a good fit for all involved.
- Quick turnaround time. We know you have lots of options so we move fast usually in less than a week from start to finish.
