Summary
What you’ll impact
Asymptote is seeking a Founding Security Engineer to build the AI Detection & Response platform that secures AI agent activity across enterprise environments. The role involves designing telemetry, detections, investigation and response capabilities, and shaping product direction while working closely with founders and security researchers.
Responsibilities
What you'll do
- Design and build systems that ingest, normalize, and analyze high-volume AI agent activity.
- Develop the security primitives that turn raw agent telemetry into useful 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.
- 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 emerging threats.
- Build behavioral detection systems that identify suspicious sequences of agent activity rather than relying only on static indicators.
- Develop the infrastructure for rapidly deploying, evaluating, and improving new detections.
- Determine what security-relevant 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 capable of representing agent activity across heterogeneous systems.
- Make telemetry collection performant, reliable, and useful for real-world investigations.
- Build the systems security teams use to understand what an agent did, why it happened, and what was affected.
- Develop investigation primitives for reconstructing complex agent activity across tools and environments.
- Build response mechanisms that allow security teams to contain malicious or compromised agents.
- Create workflows that turn detections into actionable security outcomes rather than another stream of alerts.
- Partner closely with our security research team to reproduce emerging attacks and turn them into product capabilities.
- Build adversarial environments for testing Asymptote against real attack techniques.
- Develop evaluation frameworks for measuring detection quality, false positives, and coverage.
- Contribute security tooling and infrastructure back to Beacon where appropriate.
- Work directly with the founders to define Asymptote's architecture and product direction.
- Talk with security teams at enterprise design partners to understand how AI agents are changing their environments.
- Help determine which security problems we solve, which abstractions we build, and where we invest technically.
- Own major parts of the product from initial design through production deployment.
Requirements
What you’ll bring
- 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.
