About this role

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. Company culture is at our core 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. Do our values speak to you? Pursuit of excellence Resilience Mission focus Accountability Embracing conflict About the team We are standing up a new team for the QSIDS (Qohash Sensitive Information Detection System) launch, dedicated to the detection engine. A central focus of this team is the integration of embedded AI, machine learning models that run directly on the device and in-system.

It is about high-performance, low-resource, on-device inference, embedded into the detection engine itself. The engine is built in Go, with a strong emphasis on performance and minimal resource footprint. Who you are You're a hands-on Go developer who likes living close to the metal - profiling hot paths, trimming allocations, and making concurrent systems behave predictably under load. You enjoy integration work: wiring components, native libraries, and models into a coherent engine, and making the seams disappear.

You take pride in owning what you ship, watching how it behaves in production and iterating to keep it fast and reliable. You bring strong engineering fundamentals, write tests as a matter of course, and collaborate naturally, helping the team converge on quality decisions. You're comfortable with the pace and ambiguity of a startup, and you care about the outcome, not just the code. What you will do Design and build a highly efficient cross-platform detection engine for Windows, macOS, and Linux.
