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. 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 Preferred Qualifications Experience with workload identity technologies such as SPIFFE/SPIRE, Kubernetes service accounts, or cloud workload identity. Experience securing identities and authorization for AI agents and other autonomous systems. Experience with just-in-time access, zero-standing-privilege, or privileged-access management platforms. Familiarity with identity threat detection and response. Experience building IAM controls for multi-account cloud environments. Familiarity with NIST SP 800-63, NIST SP 800-207, CIS benchmarks, and relevant identity-security guidance. Experience supporting compliance programs such as SOC 2, ISO 27001, or FedRAMP. Security certifications such as CISSP, CCSP, or equivalent. Contributions to the identity or security community through open-source projects, publications, or conferences. Durable Skills AI fluency means using these tools to amplify human judgment, not replace it. We believe people with these skills will thrive as work and technology continue to evolve: Awareness: Understand
