Security Engineer Lead, Corporate Security

About the Role: 

We’re looking for a Security Engineering Lead to own and drive Anthropic’s Corporate Security program. This is a player-coach Tech Lead Manager (TLM) role: you’ll be both the most senior technical individual contributor on corporate security and the people leader for a lean, high-impact team of Security Engineers. You will set the technical direction, write code and ship tooling alongside your team, and build the culture and processes that allow the team to scale.

Corporate Security at Anthropic encompasses everything that protects our people, endpoints, networks, SaaS ecosystem, and corporate data—the full surface area outside of production infrastructure. The scope is broad and the team is deliberately small, which means you’ll need deep technical skills across multiple domains, strong judgment about where to invest, and a bias toward automation and engineering-driven solutions over manual process.

You’ll report into Security leadership and partner closely with IT, Infrastructure Security, Detection & Response, and GRC teams. This role is high-visibility and high-autonomy: you’ll be expected to define the roadmap, make architectural decisions, and represent Corporate Security across the company.

Responsibilities: 

Technical Leadership & Hands-on Engineering

• Own the security architecture, tooling, and controls for Anthropic’s corporate environment end-to-end, including endpoint fleets (macOS, Windows, ChromeOS), campus and office networks, SaaS applications, mobile devices
• Design, build, and ship security automation, integrations, and internal tooling—including leveraging Claude and LLMs to accelerate security workflows
• Define and enforce security baselines, hardening standards, and configuration policies across all corporate platforms
• Define what it means to operate safely in an environment where AI agents act more like humans than actual humans
• Evaluate, select, deploy, and operate corporate security tools (EDR/XDR, MDM, ZTNA, CASB/SSPM, email security, DLP, browser security, etc.)
• Drive vulnerability management for corporate assets, including patch orchestration, risk-based prioritization, and exception management
• Lead security reviews of new SaaS adoptions, corporate infrastructure changes, and IT projects

People Leadership & Team Building

• Manage, mentor, and grow a purposefully lean team of Security Engineers; set clear expectations, run effective 1:1s, and create an environment where engineers do the best work of their careers
• Hire and build the team as scope expands—own the hiring bar and pipeline for Corporate Security Engineering roles
• Balance your own IC contributions with the team’s needs; know when to go deep on a problem yourself and when to delegate and coach
• Foster a culture of operational excellence, blameless incident review, and continuous improvement

Strategy & Cross-Functional Partnership

• Define and own the Corporate Security roadmap, aligning investments to Anthropic’s risk profile and growth trajectory
• Partner with IT Operations to ensure security is embedded in endpoint provisioning, network design, and SaaS lifecycle management
• Collaborate with Detection & Response on telemetry coverage, detection engineering, and incident handling for corporate-sourced events
• Partner with Infrastructure and Security Engineering teams to ensure security standards are consistent across all of Anthropic
• Communicate security posture, risks, and investment needs to Security leadership and cross-functional stakeholders clearly and persuasively

You may be a good fit if you:

• Have 8+ years of Security Engineering experience in a corporate/enterprise security domain (endpoint security, network security, SaaS security, identity, or a combination)
• Have 2+ years of experience managing or tech-leading a team of engineers, with a demonstrated track record of developing talent and shipping results through others
• Are a strong engineer who still writes code regularly—you can prototype a tool, write a detection, build an integration, or debug a complex configuration issue
• Have deep experience with macOS fleet security (this is our primary platform) and solid working knowledge of Windows and ChromeOS security
• Have hands-on experience deploying and operating EDR/XDR, MDM, ZTNA/zero trust, and identity security solutions at scale
• Understand modern SaaS security challenges: shadow IT, OAuth token sprawl, data exfiltration paths, SaaS-to-SaaS integrations, and SSPM/CASB tooling
• Can work independently with high autonomy, manage ambiguity, and make sound risk-based prioritization decisions in a fast-paced environment
• Have excellent communication skills and can translate complex security topics into clear recommendations for technical and non-technical audiences

Strong candidates may have:

• Securing corporate environments at high-growth AI, cloud, or developer-tools companies 
• Maturing a Corporate Security function from early stage, including defining scope, selecting the initial toolset, and hiring the founding team
• Advanced macOS security (system extensions, endpoint security framework, MDM profile engineering, Declarative Device Management)
• Network security architecture for hybrid/multi-office environments, including SD-WAN, ZTNA, DNS security, and network segmentation
• Browser security and isolation technologies (e.g., Island, Talon/Palo Alto, Chrome Enterprise)
• Proficiency in Python, Go, or similar languages for building security tooling and automation
• Experience leveraging LLMs/AI to augment security operations, build investigative tooling, or automate policy enforcement
• Familiarity with IaC (Terraform), CI/CD pipelines, and DevSecOps practices as they apply to corporate infrastructure management
• Mobile security for iOS/Android in a BYOD and corporate-managed device environment
• Data Loss Prevention (DLP) program design and implementation across endpoints, email, SaaS, and cloud storage

Deadline to apply: None. Applications will be received on a rolling basis.
