AI Agent Security | Country Manager | Zenity

Country Manager

Tokyo Full-time

Description

Zenity is the leader in AI Agent Security and the first company to bring an agent-centric security platform to market. As enterprises accelerate AI agent adoption, we are establishing the security framework for how AI agents are secured and governed at enterprise scale. We deliver full-lifecycle visibility, governance, detection, prevention, and response for AI agents from build time to runtime, across SaaS, home-grown platforms, and end-user devices.

Backed by $180M+ in total funding, including a $125M Series C led by Norwest, with participation from SoftBank Vision Fund 2 and Microsoft's M12, Zenity is trusted by Fortune 500 and Global 2000 enterprises worldwide.

Join us in shaping how AI agents are secured at enterprise scale.

The Role

We are hiring a Country Manager for Japan who will own all commercial outcomes in the region. This is a player-coach role: in the near term, you will carry a quota and close enterprise business directly. Over time, you will hire and lead a team, build out the partner ecosystem, and shape how Zenity grows in Japan for the long term.

You will report directly to the CRO and operate with significant autonomy. This is not a role that comes with a full playbook. You will need to build one.

Why This Role Matters

Japan is a strategic priority for Zenity. We have existing customer relationships and established partnerships in market; the foundation is in place. What we do not yet have is the local leadership to build on it.

This is a rare opportunity: come into a market where the work has started, own it fully, and build it into something significant. The person in this role will be Zenity's first dedicated leader in Japan, responsible for translating early traction into a scaled, sustainable go-to-market motion.

Working Model

This role is based in Tokyo and works closely with Zenity's global team across sales, customer success, product, and leadership. You will have significant autonomy to drive the Japan strategy, with direct access to and support from the CRO.
