What the job involves

• We’re looking for a Senior Security Software Engineer to provide technical leadership within Security Operations
• You’ll own and evolve foundational platforms that help Pinterest govern cloud infrastructure, identify and remediate vulnerabilities, automate security compliance and integrate security reviews into engineering workflows
• You’ll translate complex and sometimes ambiguous security requirements into scalable controls, services and paved paths across AWS, CI/CD and the software-development lifecycle
• This role combines hands-on software and infrastructure engineering with architectural ownership, cross-functional influence and responsibility for the reliability and adoption of security-critical capabilities
• Own the architecture and technical direction of critical Security Operations systems, automation and developer-facing security capabilities
• Design and build reliable production services, infrastructure-as-code and policy-as-code that govern Pinterest’s cloud resources and software delivery workflows
• Develop scalable guardrails and paved paths for areas such as identity and access, infrastructure changes, cloud configuration, service hardening and CI/CD security
• Improve how Pinterest identifies, prioritizes and remediates security issues by integrating vulnerability signals, automating triage and creating clear accountability
• Lead complex, cross-functional initiatives from problem definition and technical design through implementation, adoption and operational maturity
• Establish engineering standards and provide technical guidance that improve the quality, reliability and effectiveness of security systems and partner teams, using AI responsibly to accelerate this work
• Apply AI to accelerate engineering and security analysis while defining appropriate validation, data-handling and accountability practices
