About The Position

AI agents are changing how software gets built, deployed, and operated. They also introduce an entirely new attack surface: prompt injection, secret exfiltration, escalation paths, and insider threat amplification. Most organizations are adopting agents faster than they’re securing them. We’re building the products that fix that. bunny.net is building a new product line focused on AI security: giving customers the infrastructure to route, observe, and control AI traffic at the edge, and the security layer to protect against the threats that come with agent adoption. Detection, prevention, access enforcement, and visibility into what AI systems are actually doing. This role sits at the center of that effort. You'll join the AI team as one of its first members, helping define the security models, controls, and products that help customers safely adopt AI at scale. You'll do it as part of an AI-native team, building, testing, and shipping through AI agents every day rather than writing code by hand. The challenges are real, the playbook is still being written, and many of the best practices haven't been established yet. You'll help define them.

Requirements

7+ years building and architecting complex production systems
Background in application security, infrastructure security, or both
AI-native workflow, meaning you build alongside AI agents every day and know how to turn their output into production-ready systems
Senior-level software architecture skills, including thinking in trust boundaries, failure modes, and system-level risk, not just features
Experience with the failure modes and guardrails of agent-driven development and how to mitigate them

Nice To Haves

Deep understanding of how agents change the attack surface: prompt injection, secret exfiltration, escalation paths, insider threat amplification
Experience building security products such as WAFs, API gateways, or threat detection systems
Experience using AI and agents to build or improve production security tooling
Familiarity with edge computing, CDN infrastructure, or large-scale distributed systems

Responsibilities

Help design the security architecture behind bunny.net's AI security products: the threat models, detection systems, access controls, and enforcement policies that protect customers from AI-era attacks
Build core security capabilities, including prompt injection detection, secret protection, agent auditing, and access enforcement
Work with Product and AI leadership to identify the threats that matter most and decide what to build next
Build security products on bunny.net's global edge network, bringing AI security to a globally distributed platform operating at massive scale
Help secure bunny.net's internal AI platform and apply those learnings to customer-facing products
