Security Engineer

• Security at METR is becoming its own dedicated team, and you would be one of its first hires.
• Managing endpoints and securing development environments, cloud platform security, safely sandboxing agents and evaluations.
• Run targeted red-team exercises against our own systems and build automated AI red teaming.
• Build AI systems that can quickly triage and respond to threats, both from internal agents and external attackers.
• Detection engineering, telemetry pipelines, incident response, and hardening across our cloud infrastructure, endpoints, and identity systems.
• Securing a unique attack surface: METR's evaluation infrastructure runs frontier AI agents, executing untrusted, model-generated code at scale.
• Work closely with researchers to make dangerous-capability experiments safe to run.
