Job Summary
About Simbian AI
Simbian AI is building the worlds first autonomous AI security agent - one that thinks hunts and responds like a seasoned security analyst at machine speed. Were backed by top-tier investors and trusted by security teams who are drowning in alerts. Were now building an AI pentesting agent that autonomously probes exploits and reports vulnerabilities across modern infrastructure. Youll be the adversarial brain behind it. The Role Were building AI that does offensive security work. Not assists with it - actually does it.
Were looking for a Red Teamer who brings deep hands-on attack expertise and wants to turn that knowledge into AI-powered products. This is not a role where you run red team engagements. You are the expert who makes our AI agents think and act like skilled attackers - across whatever domain were building in.
What Youll Do
- Be the offensive security brain behind our AI agents - defining how they reason plan and execute across attack scenarios
- Translate attacker methodology into structured workflows the AI can learn from and act on
- Cover the breadth of offensive security: network and web pentesting phishing and social engineering cloud and infrastructure attacks adversary emulation threat intelligence
- Validate product output against what a skilled human attacker would actually do - close the gap when the AI falls short
- Research emerging techniques across the offensive security landscape and get them into the product - Work closely with engineering to improve agent accuracy realism and coverage
- Document attack logic edge cases and findings in ways that feed back into the product
Requirements
What Were Looking For
- 3-6 years in offensive security red teaming or penetration testing
- Strong offensive security background across multiple domains: web network cloud social engineering or adversary simulation
- Real-world experience: pentesting bug bounty red team engagements CTFs or security research - Ability to break complex attack chains into structured repeatable steps - Someone who thinks in attacker TTPs not just tools
- Curiosity about AI and genuine interest in building with it not just using it
Bonus:
- Experience with LLMs agentic systems MITRE ATT&CK or security automation
- Working knowledge of prompt injection jailbreaking techniques and OWASP Top 10 for LLMs - CEH OSCP or equivalent - preferred not required
Why This Is Different
Most red teamers execute campaigns. Here you build the agent that runs them. Your expertise becomes the product - and scales beyond what any single person could do alone.
Nice to Have
- Experience red teaming agentic AI systems or multi-agent pipelines
- Background in threat intelligence or APT simulation
- Contributions to bug bounty programs (AI/ML targets a plus)
- Familiarity with AI safety and alignment concepts
Benefits
-Work on a problem most security teams havent even defined yet
- Direct impact on product - your findings shape what we build
- Remote-first async-friendly culture
- Competitive comp equity at an early-stage AI security company - Work alongside people whove shipped security products at sc
Required Skills:
3-6 years in offensive security red teaming or penetration testing - Hands-on experience with at least one of: LLM security adversarial ML or AI system testing - Strong fundamentals in web app API and network pentesting (OWASP MITRE ATT&CK) - Scripting proficiency: Python required; familiarity with LangChain LlamaIndex or similar AI frameworks is a strong plus - Working knowledge of prompt injection jailbreaking techniques and OWASP Top 10 for LLMs - CEH OSCP or equivalent - preferred not required - Strong written communication: your POCs need to be readable by both engineers and executives
