About the Company

Our client is building infrastructure required to secure and control the most powerful forms of artificial intelligence.

The company helps large enterprises observe, secure, and optimize their internal AI usage at massive scale, providing visibility into what models and agents are doing, what they access, what they cost, and the risks associated with their actions.

The company is operating at an extremely early stage with a very small founding engineering team and is already working with major enterprise customers.

The platform is focused on securing the emerging world of cloud-based AI agents by combining real-time telemetry, identity, security infrastructure, behavioral analysis, and AI-powered detection and enforcement.

The founding team brings deep experience across AI security, enterprise software, infrastructure, and high-scale engineering organizations, with the company backed by leading technology investors and experienced enterprise technology operators.

As a Founding Engineer, you'll have significant ownership over the platform's architecture and technical direction while building systems that secure AI agents and enterprise AI infrastructure at unprecedented scale.

This is an opportunity to work directly with enterprise customers, build real-time AI security infrastructure, solve difficult distributed systems and machine learning problems, and operate as one of the earliest technical members of a highly ambitious company.
