What We Build

Our mission is to build the future of cyber defense. We are the architects of autonomous security agents and agentic pipelines, creating a new class of resilient systems that can intelligently detect, analyze, and remediate threats with minimal human intervention. We are moving beyond traditional cybersecurity to build a platform that anticipates, learns, and acts on its own.

What You'll Do

• Design and build the core components of our autonomous security agents, from data ingestion and analysis to automated response frameworks.
• Architect and implement scalable "agentic pipelines" that allow multiple AI agents to collaborate on complex security tasks and remediation flows.
• Lead the technical design of new, large-scale systems, writing design docs and breaking down complex problems into solvable parts.
• Write clean, high-performant, and secure code, setting the standard for quality on the team.
• Conduct thorough code reviews and provide critical technical feedback to your peers to maintain our high engineering bar.
• Mentor other engineers on the team, sharing your expertise in system design, AI, and secure coding practices.
• Research and prototype LLM applications, and agent-based technologies to solve cutting-edge cybersecurity challenges.
• Own the full lifecycle of your services, from ideation and development to deployment and operational excellence.
• Collaborate closely with product management and security research teams to translate complex security requirements into scalable, autonomous solutions.
• Drive optimization of our CI/CD pipelines, testing frameworks, and development processes to improve velocity and reliability.
