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.

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

Requirements

• 5+ years of security engineering experience, including substantial IAM or identity-security experience
• Hands-on experience with Okta, Okta for AI Agents and Sailpoint, or comparable technologies
• Strong understanding of authentication, authorization, least privilege, zero trust, and identity lifecycle management
• Experience with SAML, OAuth 2.0/2.1, OpenID Connect, SCIM, and MFA
• Experience designing RBAC or ABAC authorization models
• Experience securing human and non-human identities, including services, workloads, automation, and CI/CD systems
• Experience with agentic frameworks and MCP tool integration
• Experience implementing access reviews, privileged-access controls, and joiner/mover/leaver workflows
• Proficiency in at least one programming or scripting language, such as Python, Go, Java, Ruby, or Bash
• Experience with infrastructure-as-code, policy-as-code, APIs, and security automation
• Bachelor’s degree in Computer Science, Information Security, or a related field, or equivalent practical experience
