## About Rift

Rift is the universal filesystem for agents. It keeps everything a person's agents produce in one encrypted filesystem, on all of that person's machines.

## The role

You will own how Rift decides who can read what. Your work is the reason we can say that we cannot read a user's files.

## What you will do

- Design key management for folders shared across many people and agents.
- Define what granting, approving and removing access guarantee, and test each guarantee against an attacker.
- Write the threat model and keep it current.
- Review every change that touches access or encryption.

## You may be a good fit if you

- Have written the cryptography in a product people used.
- Have worked on secure messaging, access control or encrypted storage.
- Write designs that engineers outside cryptography can follow and challenge.
