About The Position

Alignment is building the future of team intelligence — a platform that automatically gathers Slack messages and scattered files into one organized knowledge base. It structures information with no manual work, while an AI agent reads raw data, verifies facts across business apps, and delivers reliable, up-to-date answers.
