[Remote] Founding AI Engineer

Note: The job is a remote job and is open to candidates in USA. ManticoreAI is an AI-native offensive security company backed by leading US cybersecurity investors. They are seeking a Founding AI Engineer to take ownership of their production platform, enhancing its capabilities and reliability while working closely with the founder.

Responsibilities

• Multi-agent AI that reasons through an attack the way a senior pentester would, plans its next move, and adapts as it goes
• Real exploitation against live targets, not signature matching, including web, API, and network paths
• Browser-driven testing for modern web apps
• Post-exploitation and lateral movement once a foothold is established
• Reliability, cost, and speed of the whole agentic pipeline at production scale

Skills

• 6+ years shipping Python async in production (real asyncio, not just typing async def)
• Real offensive security background — OSCP / OSWE / OSEP or equivalent war stories. You can read a pentest report and know where the real finding is
• Built or heavily modified LLM agent systems in production
• Comfortable owning and navigating large, complex codebases
• Strong systems debugging: async deadlocks, event-loop issues, process trees, signal handling
• You use AI tooling daily (Claude Code, Cursor, or equivalent). If you think AI tools make engineers worse, this isn't for you. We live in this stack
• Strong written English (async-first team across timezones)
• You read documentation and update it. Our internal docs are deep, and how you use them in the take-home tells us a lot
• Hands-on with offensive tooling (the standard Kali toolkit)
• Prompt engineering at scale (many interdependent prompts in production)
• Postgres experience
• AI safety or red-teaming AI systems
• Previous startup or founding-engineer experience
