# Founding Full Stack Staff Engineer - Frontier Cyber Security

Hiring for Lean SuperIntelligence — via Flexiple, the recruiting partner on this role. ABOUT US Lean SuperIntelligence (LSI) is an AI lab building self-improving cybersecurity foundation models for enterprises. LSI publicly announced LSI-Offense-1 and LSI-Defense-1 on October 9, 2026, alongside the closing of its initial pre-seed financing. LSI-Offense-1 discovers, exploits and validates vulnerabilities; LSI-Defense-1 detects, investigates and responds to threats. The models improve through an offense-defense feedback loop inside LSI Cyber World Models, simulated enterprise environments that turn attack and defense outcomes into training signals. The models are designed for enterprise-controlled deployment, including on-premises and air-gapped environments, with customization on private enterprise data. Access is currently limited to selected design partners. Founded by Chandra Khatri, LSI brings together foundation-model builders and security researchers. Its announced backers include investors and angels with AI and security leadership experience at OpenAI, CrowdStrike, SentinelOne, Zscaler, Commvault and Gruve AI.
