Culture + Values

A startup person: you aren't driven by titles or hierarchy, and prefer efficiency to excess process.
Motivated: you are self-motivated and bring an enthusiasm to the team that goes beyond clocking in and clocking out.
A team-player: Oklo genuinely is a team; we aren't about taking credit for ourselves or pushing blame to others.
An excellent communicator: technically competent and a clear, upbeat communicator.
Creative: able to identify and invent solutions when things fall outside clear scopes or processes without micromanagement.
Detail-oriented: focus on excellence, consistency, quality; even grammar and spelling matter.
