Senior Full Stack Developer, Cyber

Qohash is building the zero copy data security control layer, enterprises need to adopt AI safely.

Our platform, Qostodian, helps large organizations discover, classify, govern, and remediate sensitive unstructured data across their most critical data sources without moving or copying the data. This zero copy architecture reduces exposure, preserves data sovereignty, and allows enterprises to secure data directly where it lives.

This matters because AI adoption is increasing the risk, complexity, and urgency of enterprise data security. Before organizations can safely deploy AI agents, copilots, retrieval systems, or automated workflows, they need to know where sensitive data lives, who and what can access it, and how to enforce controls at scale.

Our 5 core values are more than just words, they are a way of life for us. We know that companies with a strong culture and a higher purpose perform better in the long run.
