Callisto Team is looking for smart-contract security auditors. Security auditors should check smart contracts for errors and publish reports. Smart-contract security auditors are paid depending on the result of their audit reports.
Security departments of Callisto operate through github. The workflow is described here. We aim to develop a self-sustaining, self-governed structure of security auditing organization, which provides free-of-charge security audits for end users (smart-contract developers or 3d party investors).
