Security Engineer, IAM

Role Description

Security Engineers at Dropbox safeguard our digital ecosystem alongside a diverse team of professionals dedicated to protecting our products and users. Trusted by millions, our mission is to integrate security seamlessly into Dropbox, empowering confident collaboration.

In this role, you'll build and operate the identity and access controls that help Dropbox employees, services, and AI agents access what they need securely. You'll combine security engineering and automation to strengthen authentication and authorization, enforce least privilege, and simplify identity lifecycle management across our infrastructure. Working closely with Infrastructure, Corp Engineering, Developer Platform, and Incident Response, you'll make secure access easier to use and maintain reliable IAM services as Dropbox adopts new AI tools and agentic workflows.

Responsibilities

• Design, deploy, and operate IAM controls across Dropbox's cloud and on-premises infrastructure.
• Design and implement secure identity, authentication, and authorization controls for AI agents and other non-human actors.
• Implement least-privilege access using RBAC, ABAC, permission boundaries, service control policies, and just-in-time access.
• Design secure integrations using SAML, OAuth 2.1, OpenID Connect, SCIM, and SPIFFE/SPIRE.
• Automate identity lifecycle processes to ensure access is granted, modified, and revoked promptly.
• Develop identity guardrails using infrastructure-as-code and policy-as-code.
• Build monitoring and alerting for anomalous authentication, privilege escalation, credential misuse, and unauthorized access.
• Partner with Incident Response to investigate identity-related incidents and rapidly revoke compromised access.
• Conduct security reviews and threat modeling for new identity architectures and integrations.
• Maintain IAM services with strong reliability, documentation, operational ownership, and on-call support.

Many teams at Dropbox run Services with on-call rotations, which entails being available for calls during both core and non-core business hours. If a team has an on-call rotation, all engineers on the team are expected to participate in the rotation as part of their employment.
