About the Team
The Enterprise Identity team serves as Workday’s first and most critical line of defense. We own, architect, and evolve the Identity and Access Management (IAM) systems that govern exactly who gets access to internal resources, what they can do with that access, and why.
Operating across one of the most complex enterprise cloud environments in the software industry, our technical scope spans human, non-human, and multi-cloud identity systems. From designing and implementing practical Zero Trust controls and conditional access policies, to engineering automated workflows for seamless onboarding, role transitions, and offboarding across the company, this team is at the forefront of how Workday secures its digital ecosystem.
We are also pioneering work on the AI and agentic frontier, addressing the emerging challenge of securing autonomous AI agents, non-human identities (NHIs), and service-to-service trust models in production. Our work in privileged access governance is focused on hardening system access, reducing long-lived elevated privileges, and driving the transition toward right-sized entitlements and least-privilege models.
At Workday, identity is not a back-office IT support function. It is a core security boundary and engineering enabler. The Enterprise Identity team directly influences how safely Workday builds and ships products, acting as a crucial pillar in protecting the vital data and infrastructure of over 60 million users. If you are energized by meaningful security challenges with real organizational impact, this is the team for you!
About the Role
As a Senior IAM Engineer on the Enterprise Identity team, you will play a central role in modernizing the design, architecture, and evolution of our enterprise identity ecosystem. You will secure digital identities across cloud, hybrid, and on-premises environments while balancing hands-on engineering with technical mentoring of more junior team members. You will also oversee the administration of IAM services in our European Sovereign Cloud.
Responsibilities
In this role, you will be responsible for:
•
Architecture and Design: Contribute to the design, implementation, and scaling of enterprise IAM solutions, including Single Sign-On (SSO), Multi-Factor Authentication (MFA), Lifecycle Management, and Directory Services.
•
Cloud Identity: Define and implement IAM strategies across multi-cloud environments (e.g., AWS, Azure, GCP), focusing on CBAC, RBAC, PBAC, and ABAC as part of a Zero Trust and Zero Standing Privileges security model.
•
Automation and DevSecOps: Champion “Identity as Code” by automating provisioning, de-provisioning, and access review workflows using CI/CD pipelines and scripting.
•
Mentorship and Leadership: Provide technical mentorship to mid-level and junior engineers, establish engineering best practices, and lead incident response for complex identity-related issues.
•
Compliance and Audit: Partner with Risk and Compliance teams to ensure identity practices align with frameworks such as SOC2, ISO 27001, and GDPR.
•
Regional Operations Oversight: Provide SRE oversight of IAM services in the European Sovereign Cloud environment.
•
AI-Driven Development: Use AI tools and techniques to accelerate development and improve engineering workflows.
•
Automation at Scale: Identify and implement automation opportunities to streamline IAM operations and reduce manual effort.
•
AWS IAM Modernization: Contribute to the redesign and modernization of how the team manages IAM in AWS.
