About the Job

Requirements

  • At least 10 years of experience in cybersecurity or related engineering disciplines, including substantial experience leading complex technical initiatives at principal, staff, lead, or equivalent scope, with continued hands-on engineering contributions.
  • Demonstrated proficiency in at least one general-purpose programming language, such as Python, Go, or TypeScript, with recent experience writing, testing, debugging, and maintaining production software.
  • Experience building security tools and integrations using APIs, SDKs, and event-driven workflows, including authentication, authorization, secrets management, error handling, and safe failure behavior.
  • A demonstrated record of personally shipping and operating security capabilities that measurably reduce risk or manual effort.
  • In-depth knowledge of cloud security architecture, including AWS or GCP, and SaaS ecosystems such as Google Workspace, Slack, or Okta.
  • Deep implementation and troubleshooting expertise in one or more enterprise security domains, with working knowledge across identity and access management, endpoint security, data protection, network segmentation, and zero trust architecture.

Responsibilities

  • Define and maintain the end-to-end enterprise security architecture blueprint covering endpoint, identity, network, and data.
  • Lead architectural reviews of major enterprise technology initiatives, such as AI adoption, zero-trust modernization, and vendor onboarding.
  • Establish architectural controls and paved paths, and perform periodic maturity assessments.
  • Design, build, and operate security services, internal tools, API integrations, and automation across identity, endpoint, SaaS, network, and data security.
  • Personally implement critical components and reference implementations, then partner with engineering teams to extend and adopt them.
  • Own delivery of key capabilities across technical design, implementation, testing, deployment, monitoring, troubleshooting, and ongoing maintenance.
  • Provide security best-practice, technology, and methodology guidance to engineering teams, and diagnose complex failures across code, APIs, identity flows, endpoints, networks, and cloud services.
  • Review and influence platform and service architecture designs to integrate security from the outset.
  • Provide risk-based architectural recommendations and influence executive stakeholders and investment decisions.
  • Develop reusable infrastructure, configuration, and policy as code to automate control deployment, drift detection, and remediation, reduce exceptions, and shorten adoption time through shared security capabilities.
  • Enable safe, rapid change through peer review, automated tests, and CI/CD for software, integrations, policies, and configuration, with staged rollouts and recovery plans.
  • Work with security teams, engineering partners, product leaders, and principal architects to drive large-scale security initiatives.
  • Serve as the architecture liaison between Corporate Security and Product Security to support a unified security strategy across enterprise and customer-facing environments.
  • Mentor security practitioners and security engineers across seniority levels and corporate domains through implementation, debugging, and secure software development.
  • Lead code and design reviews.
  • Publish an enterprise security architecture vision and reference patterns, and establish clear OKRs and metrics adopted by partner teams.
  • Improve key risk measures, including privileged access, SaaS misconfigurations, device posture, and data exfiltration.
  • Define SLOs for critical controls, improve MTTR and MTTD, and reduce control exceptions and manual toil.
  • Drive adoption of paved-road solutions across multiple teams and shorten implementation time while reducing escalations.

Desired Qualifications

  • Excellent communication skills and the ability to simplify complex security concepts for executives and engineers.
