About the Role
We are a bootstrapped, profitable company of 130 people, all working remotely to build an AI-powered CRM. We are spinning up a new Backend Platforms team and you would be one of the first hires, offering unusual influence over the team's ownership and direction.
You will build for other engineers, focusing on:

- The transition path from Flask to FastAPI.
- Production observability standards.
