Senior AI Security Engineer

Some people accept the internet as it is. We see what it could be.

At bunny.net, we don’t wait for change. We make it happen. You won’t find layers of red tape or play-it-safe thinking here. You’ll find people who move quickly, take ownership, and push ideas all the way to the edge. Literally.

You’ll build things that solve actual problems, not add to them.

We’re not perfect, and we don’t pretend to be. But we’re always improving. We’re looking for people who want to do the same, who take pride in their work, and aren’t afraid to challenge what’s possible.

Because everyone deserves a better internet. And we’re here to help it hop faster.

AI agents are changing how software gets built and operated, and they’re opening a whole new attack surface. Security is racing to catch up.

We’re building a new security layer for AI traffic at the edge: it inspects what goes into an LLM and what comes back, detects threats in real time, and stops them without getting in the way.

You’ll join a small AI team with a lot still to define. From prompt injection and data leakage to agent security and real-time detection, you’ll take hard problems from idea to production, and help shape the playbook others will follow.

If you like building in fast-moving territory where your decisions actually matter, you’ll feel right at home.
