Pinterest is looking for a Senior Director of Security Engineering to serve as the CISO's operating partner and lead the engineering execution for the entire Product and Cloud Security areas of our information security program. This is not a conventional security‑leadership hire — it is a mandate to run a significant, multi‑domain engineering organization at the intersection of product security, cloud and infrastructure security, and privacy engineering.

Reporting directly to the CISO, you will own approximately two‑thirds of Pinterest's entire information security program: a team of 40+ engineers organized across five direct reports, and a scope that spans from secure product development and platform controls to privacy‑by‑design architecture and AI security. You will translate Pinterest's security and privacy strategy into measurable, durable engineering outcomes — and serve as a trusted partner to Engineering, Product, Legal, Privacy, and Trust & Safety leadership.

• Own the end-to-end security engineering organization spanning product security, application security, identity and access management, vulnerability management, security architecture, supply chain and AI/product‑risk controls, and cloud infrastructure security.
• Define and drive Pinterest's multi‑year security engineering roadmap; translate risk appetite and policy into executable, measurable engineering programs across product and infrastructure life cycles
• Serve as the executive owner of threat modeling, secure design review, and developer security enablement — embedding security as a first‑class capability within Pinterest's engineering culture
• Partner closely with VP‑level engineering, product, and infrastructure leaders and teams to seamlessly integrate security into the software development lifecycle. Leverage relationships with strategic partners such as AWS to operate at the leading edge of cloud security best practices
• Lead Pinterest's security privacy engineering function as a product‑grade capability: privacy‑by‑design systems, data inventory and classification, consent and preference controls, data lifecycle and deletion.
• Drive the maturation of privacy engineering beyond compliance response — building reusable, scalable engineering primitives that make privacy‑preserving development faster and safer across Pinterest's product surface area
• Champion and evangelize foundational security platforms and libraries to ensure a secure production and data infrastructure. This includes adoption of enterprise grade IAM (e.g. machines, workloads, agents, users) systems, secrets management, network security and container security.
• Own Cloud Governance:
  Leads cloud security posture and governance. Define and enforce standards for IaC security, AWS resource provisioning, CI/CD pipeline security, and overall security policies.
• Direct the maturation of the Security Compliance & Accountability platform. Establish and enforce rigorous metrics across multiple focus areas, including AAA (Authentication,…
