Hands-On Engineering

• Design, implement, and operate core IAM platform services.
• Build integrations between identity providers, API gateways, authorization systems, secrets management platforms, and SaaS products.
• Develop services supporting user lifecycle management, machine identity management, delegated administration, access reviews, and compliance reporting.
• Implement secure token exchange, service-to-service authentication, and federated identity workflows.
• Build APIs, automation, and self-service capabilities for onboarding, provisioning, and access governance.
• Troubleshoot and resolve complex scalability, reliability, and security challenges across the platform.

Security & Governance

• Design authorization models supporting RBAC, ABAC, delegated administration, and multi-tenant environments.
• Define controls for least privilege, separation of duties, credential management, and privilege escalation prevention.
• Ensure complete auditability of access grants, modifications, reviews, and revocations.

• Experience designing and implementing RBAC, ABAC, policy-based authorization, entitlement management, and access governance solutions.
• Experience building and operating secure API platforms, service-to-service authentication, and machine identity systems.
• Strong software engineering skills with modern backend technologies, cloud-native architectures, and infrastructure automation.
• Experience designing highly available, scalable, and secure distributed systems.
• Proven track record of leading large cross-functional technical initiatives while remaining deeply hands-on in architecture, implementation, and operational ownership.

Preferred Qualifications

• Direct experience implementing or operating Zitadel or similar in a production environment.
• Experience integrating IAM platforms with enterprise identity providers including Microsoft Entra ID, Okta, Google Workspace, Ping Identity, and Active Directory.
• Experience with policy engines and policy-as-code frameworks such as Open Policy Agent (OPA), Cedar, or similar technologies.
• Experience with machine identity lifecycle management, secrets management, certificate management, and workload identities.
• Experience designing audit, compliance, governance, and entitlement review systems.
• Familiarity with compliance frameworks such as SOC 2, ISO 27001, HIPAA, PCI-DSS, NIST, or FedRAMP.
