Head of Social

Marketing

NYC Full-time

About the Role

AI agents are getting hijacked, tricked, and turned against the companies that deploy them. Zenity stops that, and our research proves it by breaking agents that the biggest companies in the world use. Our online presence doesn't yet sound like our research. That's why this role exists.

This isn't a Social Media Manager role where you schedule posts and report on impressions. You'll be the first person whose whole job is to get Zenity's name out there and make us one of the loudest, sharpest, and most-shared voices in AI security. You'll run our social channels day to day, build a B2B employee advocacy program, and come up with the creative ideas that put Zenity on the map at the biggest conferences in security.

This role reports to the CMO.

About Zenity

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 Soft Bank Vision Fund 2 and Microsoft's M12, Zenity is trusted by Fortune 500 and Global 2000 enterprises worldwide.

Gartner named Zenity a Market Shaper in its inaugural Emerging Market Quadrant for AI Application Security, Startup Vendors, one of only two vendors placed in the Market Shapers quadrant among nearly 20 startup vendors assessed. This follows Gartner naming Zenity the Company to Beat in AI Agent Governance earlier this year.

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

What You've Done

Must-haves

• You've spent 4+ years building an audience for a B2B tech, security, or developer brand, or for yourself, and you can show us the numbers: what took off, what flopped, and why.
• Your portfolio makes us smile and makes us think "wait, that's smart."
• You write sharply, think visually, and edit video fast. Cap Cut, Figma, Canva, or whatever you use; we care about output, not tools.
• You've turned a technical topic into something people actually share, and you can show us. Think "indirect prompt injection via MCP tool poisoning," made human.
• You've reacted to breaking news within hours, and you can tell a meme that lands from one that's three weeks stale.
• You've gotten employees, or yourself, to show up on social in a way that worked, and you can explain how you got people to post and what happened when they did.
• You use AI tools and agents in your workflow every day and can tell us which ones are overrated and why.
• You ship 10 ideas to find the 1 that takes off, and you can point to the other 9 without getting precious about them.

Bonus points

• You've built a following of your own: a channel, newsletter, community, or account.
• You've created a brand character, recurring series, or campaign people still remember.
• You've turned a conference or live event into social content that traveled beyond the venue.
• You've worked in cybersecurity, or at an early-stage startup where the role wasn't scoped for you.

• You take ownership of outcomes, not just activity, and you don't need a detailed brief on what to create.
• You move fast and hold a high bar for your own work.
• You're comfortable building where the playbook is still being written.
• You work easily with researchers, executives, and the field team, and pick up technical topics quickly.
