Security Engineer, Corporate Security

About the role

Corporate Security protects the environment Anthropic's people work in every day: their laptops and phones, their identities, the tools they collaborate in, and the company data that flows through all of it. We keep company access on devices we manage, make those devices hard to compromise, and right-size what any one of them can reach, while caring a great deal about the day-to-day experience of the people using them. We treat the work as an engineering discipline: controls as code and automation over queues, built to scale with headcount.

As a Security Engineer here you'll drive significant parts of that work end to end, set technical direction, and turn it into shipped tooling. You'll threat-model the environment to surface what matters, fix it, and bring the evidence that shapes what the team prioritizes next. This is a senior, hands-on individual contributor role.

Key responsibilities

• Drive endpoint hardening across macOS, Windows, Linux, and ChromeOS, including device management configuration, application allowlisting, patching, and browser policy, favoring controls that are versioned, reviewable, and repeatable over one-off configuration
• Extend device-trust and zero-trust access controls so company systems are reached from managed devices bound to the right person and carrying the right level of access
• Build the automation and integrations that let the team scale: joiner/mover/leaver automation across identity and device management, exception and expiry workflows, posture-driven policy, and Claude-assisted triage of review queues
• Lead SaaS and identity governance, including third-party OAuth grants, delegated admin access, chat-platform apps, browser extensions, and software security reviews
• Partner across the wider Security team, IT, and Engineering on telemetry, detections, and shared standards, and help define how a company that increasingly runs on AI agents does so securely and at scale

Minimum qualifications

• Hands-on endpoint security engineering on macOS, Windows, Linux, or ChromeOS (e.g., MDM, declarative device management profile engineering, application allowlisting, binary authorization, system extensions, endpoint security frameworks)
• Proficiency in Python and scripting languages generally; experience architecting and building integrations, automation, and internal tooling, as well as detections
• Working depth in identity and access management, SaaS security, and zero-trust access
• Threat-modeling judgment that finds the problems worth solving, with the ability to scope them, define "done," and drive them to completion
• Care for Anthropic's mission and the part corporate security plays in it

Preferred qualifications

• Experience defining the scope and choosing tooling for a security program rather than inheriting it
• Experience shipping an enforcement change to a large user population (staging rollouts, alternative paths, data-informed impact assessments)
• Endpoint depth across multiple platforms (macOS, Windows, Linux, ChromeOS)
• Mobile security across managed and BYOD contexts, including higher-risk settings such as international travel
• Experience bringing security governance to a modern SaaS environment (third-party integrations, delegated access, internally built and AI-generated apps)
• Configuration-as-code, infrastructure-as-code, and CI/CD applied to corporate infrastructure
• LLM-assisted security tooling built to materially expand team coverage
• Track record of getting security controls adopted through influence and partnership
