Job summary

Asymptote is seeking a Founding Security Engineer to build the security infrastructure for the agentic enterprise. You will shape telemetry, detections, and response in a company redefining AI security. You’ll work with founders across security research, detection engineering, product, and infra.

You’ll design, implement, and ship production-grade security capabilities and detections for high-volume agent activity in enterprise environments.

Qualifications

• 5+ years of experience in security engineering, detection engineering, security infrastructure, backend engineering for security products, or adjacent fields.
• Strong software engineering skills and experience building production systems.
• Deep understanding of security fundamentals across identity, authentication, authorization, networks, cloud infrastructure, endpoints, or application security.
• Experience working with security telemetry and turning large volumes of events into useful security signals.
• Ability to think adversarially and understand how attackers abuse complex systems.
• Experience designing and operating distributed systems, data pipelines, or security infrastructure in production.
• Comfort moving between low-level technical investigation and high-level system design.
• High agency and excited to build core infrastructure from the ground up.

Responsibilities

• Build the AI Detection & Response Platform: design and build systems that ingest, normalize, and analyze high-volume AI agent activity.
• Develop the security primitives that turn raw agent telemetry into detections, investigations, and response actions.
• Build infrastructure that operates reliably across developer environments, CI/CD systems, cloud infrastructure, and enterprise AI deployments.
• Design systems that can reason about identities, tools, permissions, resources, and actions across complex agent workflows.
• Build World-Class Detections: translate emerging attack techniques into production-grade detections.
• Develop detections for prompt injection, tool abuse, privilege escalation, credential theft, data exfiltration, malicious MCPs, agent persistence, and other threats.
• Build behavioral detection systems that identify suspicious sequences of agent activity.
• Develop the infrastructure for rapidly deploying, evaluating, and improving new detections.
• Engineer Security Telemetry: determine what security signals need to be captured across AI agents and the systems they interact with.
• Build integrations across coding agents, MCP servers, developer tooling, CI pipelines, cloud environments, and enterprise infrastructure.
• Design schemas and data models representing agent activity across heterogeneous systems.
• Make telemetry collection performant, reliable, and useful for investigations.
• Build Investigation & Response Capabilities: build systems security teams use to understand what an agent did, why, and what was affected.
• Develop investigation primitives for reconstructing complex agent activity across tools and environments.
• Build response mechanisms that allow containment of malicious agents.
• Create workflows that turn detections into actionable security outcomes.
• Work at the Frontier of AI Security: partner with security research to reproduce attacks and turn them into product capabilities.
• Build adversarial environments for testing against real attack techniques.
• Develop evaluation frameworks for detection quality, false positives, and coverage.
• Contribute security tooling back to Beacon where appropriate.
• Shape the Product: work with founders to define architecture and product direction.
• Talk with security teams at enterprise partners to understand AI agent environments.
• Help determine which problems to solve and where to invest technically.
• Own major parts of the product from design to production deployment.
