Help build the security layer for AI agents.
Founding cohort — ~20 builders.
Every serious team now filters prompts. Almost nobody governs what an agent can actually do.
Prompt filters stop text. A hijacked agent still acts — it runs shell commands, writes files, calls tools and moves data, with your credentials and your systems. OWASP now ranks it #6: Excessive Agency. That gap is one of the biggest unsolved problems in AI, and it's what we're here to close.
About Hermes Shield
We're building the action firewall for AI agents. We assume the model will be fooled — and make sure the dangerous action still can't execute.
Where we are today (no hype):
- A scanner that maps every action your agent's code can take, traces it to a real entry point, and proves which are reachable by untrusted input
- Already catches a real CVSS 9.8 CVE at the exact line
- 12 agent frameworks audited (361k+ GitHub stars); independently security-assessed twice
- Runs 100% local; built and battle-tested on our own live agents
- Pre-seed, in private beta, raising to accelerate
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What you'll do
- Ship real security features for AI agents
- Shape the roadmap and product direction with the founding team
- Run it against your own agents and make it sharper
- Break it, challenge it, and improve it
- Help define an entirely new security category
Who we're looking for
Experienced people who've built AI agents — or broken them
Especially:
- AI agent / LLM engineers
- Agent-framework developers (LangChain, LlamaIndex, crewAI, AutoGen…)
- AI security researchers
- Full-stack & backend engineers
- Product & technical designers (UX/UI)
- AI solution architects & consultants
- Open-source contributors in the agent ecosystem
What you'll get
- Access to the employee option pool — real equity, genuine skin in the game
- Early access to the technology and real influence on key product decisions
- First in line for full-time engineering & product roles as we fund and grow
- A small, ambitious community building at the frontier of AI security
